|“||(Pokémon name), I choose you!||”|
–Ash's catchphrase when calling out a Pokémon
Ash Ketchum is the main protagonist of Pokémon the Series. He is a 10-year-old Pokémon Trainer from Pallet Town in the Kanto region who has always dreamed of becoming the world's greatest Pokémon Master. The first human character to be introduced in the series, he is the winner of the Orange League and Kanto Battle Frontier and also the Alola region's Pokémon Champion, receiving the title after winning its first Pokémon League Conference. He is also one of the 8 best trainers in the Pokémon World after defeating Raihan and reached Master Class in the World Coronation Series.
On his 10th birthday, he realized he overslept. Ash rushed to Professor Oak's Laboratory to get his first Pokémon. Originally wanting to choose Squirtle, Bulbasaur or Charmander, but he ended up receiving the Pokémon Pikachu instead, as he arrived late (thus leaving him with no other Starters to choose from even though this was his birthday). At first, Pikachu did not obey Ash and kept running away, so Ash had to tie him up. After getting chased by a flock of Spearow later in the day thanks to Ash's recklessness, Ash attempted to save Pikachu from them. Seeing that Ash was so determined to help him, Pikachu protected Ash from the Spearow by electrocuting the entire flock (which was thanks to being struck by lightning at that exact moment and having his Electric-type move supercharged). From then on, Pikachu and Ash became best friends. As an unskilled Trainer, Ash traveled with Misty and Brock throughout the Kanto region, capturing new Pokémon along the way.
Ash eventually managed to collect every badge from Kanto's Gym Leaders (although some of his badges were earned out of gratitude due to varying circumstances), allowing him to enter in the Indigo Plateau Conference. Since then, Ash has continued to travel, journeying through the various regions and making new friends, from Misty and Brock to Chloe and Goh. With each new region he traveled to, Ash continued to challenge all the Gym Leaders, entering Pokémon League Conferences and catching new Pokémon while still following his goal of becoming a Pokémon Master. Since this goal is so close to his heart, he sometimes acts a bit rash and rushes to the next battle he can as fast as possible without thinking.
While Ash was traveling, he was constantly pursued by Team Rocket's Jessie, James, and Meowth, who wanted his Pikachu. They chased him across all the regions so far, and are still chasing them to this day. Team Rocket never manages to capture Pikachu though, due to Ash's other Pokémon and friends helping him.
Ash is a skinny, slender preteen with dark black hair, slightly tan skin, and brown eyes with two distinctive lightning bolt-like markings (maybe cheeks) underneath each one. Ash's pupils were not visible during the Indigo League and through the Diamond & Pearl series until the Best Wishes series made them more profound and distinguishable.
While Ash wears a few different outfits, he always wears a baseball cap, which changes depending on the region he is in. Without a cap, Ash is shown to have a cowlick and a narrow, triangular, and edgy tuft of hair in the middle of his forehead that comes to a point on the right side.

Ash wore a loose short-sleeved shirt with white and blue stripes, brown capri pants with red outlines, baggy pockets and red folded sleeves at the edge, and blue sneakers. His cap was red, dark blue, and gray, and the Poké Ball design was white. Ash also kept a silver Z-Ring on his left wrist, which was later upgraded into a black Z-Power Ring. Unlike in previous regions, Ash didn't wear fingerless gloves while he was in Alola.
As a member of the Ultra Guardians, Ash wears an indigo and white uniform with light periwinkle accents as the edge of the short sleeves, collar and inlines of his uniform are black. He wears matching indigo gloves.
In "A Young Royal Flame Ignites!", while teaming up alongside Professor Kukui disguised as Masked Royal and Ash Royal, he goes shirtless but retains his capris and sneakers from his primary outfit and dons a red flame designed wrestling mask with green and light blue with blue designs at the back of his mask. The wrestling mask was given by Kukui before they teamed up together at the Battle Royal.
Ash's sided spike hair has decreased a bit and are rounder, his eyebrows and his spike hair tuft is shorter than usually seen in previously. When he is not wearing his hat, his hair remains the same only more smoother and shorter.
Ash's two lighting bolts-like markings are slightly bigger.

Ash wears a blue vest with yellow outlines, a white undershirt with short sleeves and a red stripe, indigo shorts with black outlines, and black sneakers with blue highlights. He also wears a red hat with a black Poké Ball design formed into the letter C. During his second visit to Galar, he wears a Dynamax Band on his right wrist which he obtains from Leon. Also, Ash sometimes wear his Z-Power Ring on his left wrist or his Mega Glove whenever he is battling in an important match, especially World Coordination Series battles of the Ultra Class. During a visit to Kalos, Ash wears a Key Stone embedded to one of his gloves that resembled the ones he wore during his Unova and Kalos journeys that he obtained from Korrina.
Ash's sided spiky hair has increased a bit and are sharper like they were before, his eyebrows and his spiky hair tuft is larger than usually seen in previously. When he is not wearing his hat, his hair remains the same, only smoother and shorter. Ash's two lighting bolt-like markings still remain slightly bigger like they were throughout the entire of the Sun and Moon Series. However, his eyes are a bit wider than they were before.
Ash is very determined to be a great Pokémon Trainer. Personality-wise, Ash is a very strong person, shows confidence when battling and shows a lot of sympathy towards Pokémon, usually helping and befriending them through his long journey. As a result, Ash doesn't like Trainers who mistreat Pokémon, such as Damian and Shamus. Ash also serves as a role model for many people such as May, Dawn, N, Serena, Lillie, and Goh. In fact, he often astounds people with his skills and abilities, and unpredictability. Ash's strategy and tactics in battle are usually problem-solving, including thinking on his feet during special matches or that relate to the special and unique abilities of Pokémon. Also, Ash even takes input from his friends and has always helped him whenever he was stuck in a jam.
Ash is generally kind, brave, enthusiastic, passionate and adventurous. However, he can be stubborn, high-tempered, cocky, and sometimes impulsive at times. During his journey, Ash realized that some of those traits were affecting him, as they had caused him to lose some of his Gym battles. By recognizing this, Ash trained himself for his rematches and keeping those parts of himself in check so they wouldn't not only affect him in battle again, but also outside of it as well. Although those traits still remain, they have been shown to be less of a problem during his Pokémon battles. Thanks to his hard work, Ash has corrected the hot-headed, cocky, and impulsive parts of his personality, though he still shows them if Pokémon were being mistreated, some of his friends teasing him, and various other reasons. Since then, Ash has demonstrated much greater maturity and level-headedness both in and out of battles. In addition, he has shown to give everyone around him good advice in order to better themselves and their goals. Ash also has a fascination with science and technology, even though he cannot understand most of it.
Ash has a hard time opening up to others, as he doesn't like to talk about his feelings and his past. At first, he had difficult times when it came to taking advice or criticism from his peers, especially from his friends, but that has changed as time went on. While Ash has grown to be more open towards talking about his feelings and taking advice or criticism, he still has trouble opening up about his past sometimes. However, Ash does open up about his past with his friends and Pokémon whenever the topic comes up, though it is only if he needs someone to talk to or if he felt like talking about it, since it either reflects a mistake of his or it makes him feels comfortable sharing to anyone who is closest to him. Despite being more open, Ash still shows his stubborn side at times, although it's mostly shown when he is depressed or upset.
Ash is also honest and a Trainer that keeps his word as he usually doesn't break promises to his friends, family, and Pokémon, although he does the same thing for ones that aren't his. Sometimes, Ash makes promises to himself as well, which was shown during his first Pokémon League competition where he decided to not repeat the same mistakes he made in future League competitions. This was shown again after the events of the Kalos crisis, as Ash blamed himself for what happened when he unknowingly revealed one of his abilities to a leader of a villainous organization, which ended up putting himself and his Pokémon, Pikachu and his Kalos Pokémon, in danger. After that event, Ash decided to keep his special abilities, Aura and Bond Phenomenon, hidden from others. However, Ash has only told a few of his friends and Pokémon about his abilities as he has faith in them. So far, Ash has not told his mother, Misty, Tracey, Iris, Cilan, Lana, Kiawe, Lillie, Sophocles, Mallow, Goh and the rest of his Pokémon family about his rare abilities. When questioned or comforted about the skills or powers he possesses and the mysteries he holds, Ash had shown to panic about that or somewhat denies what he can do, which was mainly shown with Gladion and Goh, as he not only sees himself as an ordinary Trainer just on his journey to reach his goals but is also trying to protect the ones he cares deeply for. Despite this, Ash has shown to train his Pokémon that are connected to his abilities. In addition to keeping his abilities hidden, Ash decided to keep his "Alola Pokémon League Champion" reputation a secret from anyone outside the Region, excluding a couple individuals, as he wanted to resume his journey as a Trainer, not as a regional Pokémon League Champion.
On the other side, Ash has a natural, inborn love for battling. He enjoys battling Gym Leaders and anyone who challenges him, especially Trainers with a similar zeal and passion as him. However, while Ash is passionate, a good battler, and has a lot of achievements under his belt, he loses most of the Pokémon Leagues he challenges. So far, Ash has only triumphed over the Orange League in the Orange Archipelago and the Manalo Conference in the Alola region.
Additionally, despite his confidence and zeal, Ash can be modest and humble as he sometimes gets embarrassed when complimented on his skills as a Trainer, but it doesn't happen very often. In addition, Ash doesn't usually admit that he hasn't changed one bit, although it shows that he stays true to who he is, even when everyone around him notices it when he doesn't. Also, Ash has shown an insecure side, as he does worry about what his friends that he travels or travel with and his Pokémon family would think of him as a person, shown when his mother would say embarrassing things about him in front of his friends or Pokémon and when he got defensive by Brock and Misty as they reminded him about how he got their badges for petty reasons over getting them in battle right in front of his classmates along with his teachers, but one of the reasons for that side was because he knows he would get teased or scolded about it, which makes him either upset or defends himself. Although, Ash's main reason for his insecurity side was because he wants everyone around him, especially his friends and Pokémon, to see him for the person they came too known instead of who he used to be. However, Ash has seen that anyone close to him doesn't care about who he used to be, which not only shows that they have great faith in him but also that their true friends towards him. Despite the insecurities he has, Ash at times doesn't care about what anybody thinks of him, which shows how confident he is about being himself. At the beginning of his journey, Ash used to brag about his achievements but overtime didn't say anything about his previous accomplishment that much, although he does mention them sometimes but not as much in a bragging tone.
Despite his wins and losses, Ash knows he has a long way to go to make his dream a reality and continues traveling along with growing stronger to pursue it. Besides the Gym battles and Pokémon Leagues, Ash also enjoy competing in other special challenges and competitions such as the Battle Frontier in his home region Kanto, the Trials and Grand Trials in the Alola region, and the World Coronation Series.
Ash's biggest fear is losing anyone he's really close to, especially his friends and family. However, Ash is afraid to lose his Pokémon family even more, due to Team Rocket's constant attempts to steal his Pokémon away from him. Similarly, Ash is afraid of putting everyone he cares about in danger. Ever since the time Pikachu temporarily had amnesia and sided with Team Rocket, Ash became afraid that his Pokémon might leave him the same way his partner and best friend almost did. Ash is also worried that he won't meet his Pokémon family's expectations or be strong enough for them. Because of his fears, Ash sometimes doubts his Pokémon potential, which also affects his faith and trust in them as well, especially when some of them display a unique kind of power in their strengths. In the XY series, Ash almost lost himself when he let his fears get to him but Serena reminded him of who he is and helped him get his act together. However, Ash does put his fears aside to help his Pokémon become stronger, which in turn helps him get over his fears altogether, albeit slowly. Because of that, Ash is often able to help Pokémon with a rare ability perfect their true power.
Ash has also been shown to have a strong sense of justice. He doesn't hesitate to assist Officer Jenny, the Pokémon Rangers, and the International Police in their missions. He has a hatred for evil organizations, such as Team Rocket, Team Aqua, Team Magma, Team Galactic, Team Plasma, Team Flare, and Team Skull. Also, Ash doesn't like Pokémon hunters, especially J. Ash regularly risks his own life to protect Pokémon and defeat criminals.
Ash has quite a few abilities and skills. First and foremost is his athleticism, despite his young age, as Ash is very athletic and physically able. In fact, Ash was once even called a "human Mankey" because of his skill at climbing. Aside from climbing, Ash can run, swing on vines, carry heavy loads, and swim. Ash can also survive Pokémon attacks for a long period of time without taking too much damage, although it depends on the situation. Additionally, while Ash is a very talented battler, he also has some performing skills due to competing in a couple of Pokémon Contests along with watching May and Dawn's performances. Likewise, Ash has good fishing skills. Also, Ash has some cooking skills and does have good knowledge about Pokémon, due to spending a lot of time around friends who can cook and have deep knowledge about them.
Much like an Aura Guardian, Ash has the ability to sense and control Aura. However, after obtaining a Key Stone, Ash's Aura powers were increased. Also, Ash has shown the ability to use Bond Phenomenon, as showcased in the XY series with his Greninja. Ash even demonstrated great skills in utilizing Z-Moves, as shown in the Sun & Moon series. In addition, Ash even created his own Z-Crystal, Pikashunium Z, and performed an exclusive Z-Move with Pikachu known as 10,000,000 Volt Thunderbolt. Also, Ash even demonstrated some skills in utilizing Dynamax and Gigantamax, as shown in the Journey series. Unlike some Trainers, Ash is able to Gigantamax his Pikachu without having him return to his Poké Ball. In addition, Ash is able to perform Mega Evolution, which he does it with his Lucario.
Much like Dawn, Ash sometimes displays the ability to understand the feelings of Pokémon, due to spending a lot of time around them. His connection with Pokémon is so great that he even sometimes displays the ability to share a connection with Mythical or Legendary Pokémon. This is because of Ash's compassion and his strong will power to protect them; instances of it were shown when Azelf chose to connect with Ash in the Diamond & Pearl series, Battle Dimension and Galactic Battles, and when Victini linked up with him in the movie Black/White Victini and Zekrom/Reshiram.
When Ash has a connection with Mythical or Legendary Pokémon, he can feel their pain, sense if they have been captured, and see their thoughts or memories. On the other side of the link, the Pokémon can appear to Ash in his dreams to ask him for help, show him impending danger, or as a way of asking him to do something for them, as shown with Azelf, Victini, Solgaleo, and Lunala. Ash has also shown the ability to hear what Legendary Pokémon are saying, shown with Solgaleo, Lunala, and Lugia. At times, Ash has shown the ability to sense the presence of Pokémon or people whenever any of them were nearby or if they're in danger.
One of Ash's other ability is that he can learn new things really fast as he picks it up right away, although there have been times that he needed to practice first before figuring it out. Also, during battle, Ash can come up with strategies easily as he would use the environment to his advantages or find a flaw in his opponent's strategies.
Ash's battling tactics skill is, as like other Pokémon Trainers, using type advantages against his opponents, but sometimes, he uses Pokémon that have a type disadvantage. Ash's methods of battling can be overwhelming his opponents by a combination of moves using physical and special kinds of moves. One of Ash's signature traits is his adaptability and creativity, often using unorthodox methods to overcome difficult adversaries, like having his Charizard melt the battlefield during his battle against Gary's Blastoise to trap it and creating the Counter Shield to counter Fantina's Ghost Pokémon.
Since Delia is Ash's mother, they have a healthy, loving relationship, although it does run into rocky spots at times. Ash loves his mother very much and cares about her, but he gets annoyed when she embarrasses him, especially in the original series, where she constantly reminded him to change his underwear every single day. When Delia got kidnapped in The Spell of the Unown, Ash went through great lengths to get her back. Ash appreciates when his mother comments on how much he has grown as a person and as a Pokémon Trainer, and he is very grateful that his mother supports him by watching his Pokémon League battles and helping him get ready to go on another journey. Also, Ash was happy that his mother was there when he first became Champion of Alola.
While their relationship in the TV show is unknown, in the movie Pokémon The Movie: The Secrets of the Jungle, it's revealed that Ash has a close relationship with his father, the latter being the main reason he never gave up on his dreams by always encouraging him whenever other children made fun of Ash's dreams. He mentions this to Koko and talks about how Koko and Zarude's quarreling reminds him of his own relationship with his dad, implying that the two of them argued a lot, but also mentions how eventually, their quarreling will stop and they'll still care about each other, showing how close Ash and his father are.
Ash and Professor Oak have a very strong bond. This is because Oak is a family friend and has known Ash since he was little. In fact, Ash even went to Professor Oak's summer camp when he was a young boy, which was also where he met his friend Serena. Aside from the strong, almost family bond that Ash and Oak share, he also respects him as a researcher and professor. Ash sometimes goes to Professor Oak for advice and calls him whenever he needs one of the Pokémon that he has kept in storage as he trusts him to look after his Pokémon family while he travels. Much like his mother, Ash also appreciates whenever Professor Oak gives him support, whether it's for a Pokémon League tournament or for his new journeys. In addition, Ash was pleased that Professor Oak was a witness that he became the first Champion of Alola.
When Ash first met Misty, they didn't get off on the right foot. Ash was forced to "borrow" Misty's bike to save his partner's life, and he accidentally destroyed the vehicle with Pikachu's Thundershock attack. At first, Ash initially didn't want Misty around and disliked that she kept following him, as she claims that she was going to follow him around until he paid her back for her accidentally destroyed bike, though her reasons changed as she not only forgot about her destroyed bike, but also forgave him, as she understood that he had noble intentions and it wasn't entirely on purpose. Ash eventually changed his opinion about Misty, as she became a mentor to him and helped him become a great Pokémon Trainer. Despite their initial differences, Ash eventually grew to care for Misty and became best friends with her, although they do tease each other from time to time. They have each other's backs and would do anything for each other. Despite their friendship, however, aside from her fried bike, because Misty tries to keep Ash in order to make sure he doesn't flunk his training and battles, the two do argue a lot (whether if it's justifiable or not), with some of their fights leading them to almost losing their friendship and even resorting to violence, but they'll always make up from their flaws in the end. Additionally, they sometimes can be competitive with each other as they have a little bit of a friendly rivalry with one another as they try to show each other up.
After their travels in Kanto, Ash and Misty traveled through the Orange Islands and Johto together. Once their journey through Johto had ended, Ash and Misty parted ways when she was forced to run the Cerulean Gym while her sisters went on an "around-the-world" cruise, which they had won as a prize in a beauty contest. After Misty got her bike back, as it was repaired by the Viridian City's Nurse Joy and returned to her, Ash was happy that his friend would get to her hometown much faster. However, Misty became upset with Ash when he believed that the repayment for her bike was the reason she traveled with him in the first place. Ash was clueless when Misty ran out of the Pokémon Center, but Brock helped him see that she wanted to continue traveling with them. Finding that Misty was in trouble, Ash and Brock rushed to her defense. Also, Ash assured Misty that their journey together was never truly about repayment for her bike. After everything was resolved, Ash and Misty parted ways to go back to their hometowns.
Despite no longer traveling together, Ash and Misty, who decided to run the Cerulean Gym full time, maintained their strong friendship for one another. When Misty and Brock traveled to Alola, Ash was very pleased and enjoyed their time together, showing that their bond had not dwindled.
While Ash and Brock disagreed at first, they quickly became friends. Their bond soon became even stronger, resulting in them becoming best friends when they traveled the Kanto region together. When Brock stayed with Professor Ivy for a while, Ash understood his reasons. After Brock eventually returned, the two boys traveled together from Johto through Sinnoh. Through their travels, Ash grew to view Brock as a big brother figure and one of his mentors, as he would often give him helpful advice to better himself as a Trainer or help him see through his mistakes.
Ash and Brock are always there for each other. They don't usually fight with one another, but whenever they have a small fallout, they make up pretty quickly. However, Ash and Brock almost lost their friendship when one of Team Rocket's tricks got out of hand but they mended it when the truth became clear. In addition, Ash and Brock sometimes practice battles together. Ash trusts Brock to keep his Aura powers a secret. They officially parted ways when their travels in Sinnoh ended, when Brock decided to become a Pokémon Doctor and Ash continued traveling to fulfill his ambitions. After going their separate ways, Ash and Brock maintained their lasting friendships with one another, as shown when he briefly traveled to the Alola region with Misty.
Ash and Tracey are pretty close friends and have a great respect for each other, as they traveled together through the Orange Islands. They hardly disagree with each other, but when they do, they make up pretty quickly. The two boys eventually parted ways when Tracey became Professor Oak's assistant, though they still maintain a strong friendship. While Ash continued traveling, the boys sometimes see each other when the latter comes back home to Pallet Town.
May is one of Ash's best friends. They met when May witness Ash trying to save his Pikachu from danger when he was confused from an Electric build up, after an accident caused by Team Rocket. Like with Misty, Ash and his Pikachu accidentally fried May's bike. However, unlike Misty, May kept her cool and forgave them quickly as not only did she understood it wasn't on purpose, but she also never demanded payback after seeing how much Ash has been taking care of his Pikachu. After May guilt tripped her accidental destroyed bike on him into traveling together, Ash let her come along with him. They traveled through Hoenn and the Battle Frontier together, helping each other along the way. When May chose to become a Pokémon Coordinator, Ash gave her his full support and helped her in any way he could. Ash became a mentor to May and guided her in the ways of a Pokémon Trainer. In fact, they trained together for Ash's battles and for May's contests.
Sometimes, Ash and May have their fights, one of which almost caused them to lose their friendship when their ideas were working against each other as a result of them not cooperating during a battle against another team, but they always make up from their mistakes in the end. Unlike with Misty, however, many of Ash's fights with May (even their most severe one) usually does not resort to violence. Ash has faith in May as he trusts her to keep his Aura abilities hidden from anyone that wasn't their friend. Although they went their separate ways to continue making their dreams come true, their friendship remained intact, as shown when they cross paths again in Sinnoh.
Ash and Max are best friends. They share a common love for Pokémon and liked to do their own things while May and Brock went shopping in towns or cities throughout Hoenn and the Battle Frontier. Ash acts like a big brother figure towards Max and protects him. Also, Ash hardly had any fights with Max and trusts him to know about his Aura abilities. When Max was going to return to Hoenn while May traveled through Johto, Ash promised him that when he became a Pokémon Trainer, they would have a battle together. Although, Ash knows his friendship with Max will remain till the end.
Ash shares an unbreakable friendship with Dawn. As a sign of their bond, they easily get along and often high-five each other whenever something good happens for them. They also stand up for each other and have each other's backs. Similarly to what he did for May, Ash mentored Dawn in the ways of a Pokémon Trainer and helped her as a Pokémon Coordinator. Unlike with most of Ash's other female companions, Ash and Dawn hardly have disagreements with each other and are never judgmental. While Ash can annoy Dawn with his actions and vice versa and they sometimes fight a little, they show great teamwork for each other. Even the argument they had upon starting their journey as well as their most severe argument were nothing when compared to how Ash dealt with either Misty or May, as neither of these arguments were severe enough for either Ash or Dawn to lose their friendship, and they'll easily make up from their mistakes rather quickly. Unlike with Misty or May, Ash didn't find out that his Pikachu accidentally destroyed Dawn's bike until much later, though given the fact that Team Rocket was chasing them on the day they met, Dawn kept her cool with Ash and his Pikachu and quickly forgave them.
Ash also supported Dawn and cheered her on during her Contest, while she cheered him on during his Gym Battles, and she sometimes dressed up in a cheerleader outfit for him. Like with Brock, Ash and Dawn also practiced battles to help their skill levels. Through their time together, Ash sees Dawn a very trusting friend as he told her about his Aura powers. After they went their separate ways, Ash and Dawn remained best friends, shown when they saw each other again in Unova and Sinnoh.
Ash and Iris are very good friends. They respect each other's skills and the love they have for Pokémon. Much like his relationship with Misty, however, Ash and Iris do tease each other from time to time, although he also gets annoyed when she calls him a kid. In contrast to his relationship with Misty though, Ash got off to a much better start with Iris as even though it was a little sour at first when Iris yells at Ash for mistaking her for a Pokémon and throwing a Pokéball at her, he's quickly forgiven after he apologizes and admits that he had no idea where the Pokémon (Axew) was. Ash is also complemented after Iris admits even if he's still a kid, she's still impressed by his will to save Pokémon. On occasions, Ash and Iris do fight sometimes, with one of their fights almost causing them to lose their friendship when they both overreacted towards each other, but they'll always patch things up at the end. These arguments between Ash and Iris are more comparable to how the former dealt with May rather than with Misty, as many of Ash and Iris's arguments usually don't escalate into violence. The two trained for battles together during their journey together. Also, Ash enjoys doing various activities with Iris.
After arriving in Kanto, Ash and Iris went their separate ways to fulfill their dreams. However, they both knew they'd always be friends no matter where they went. After getting a letter from Iris for a battle, Ash decided to not only accept her challenge, but also see her again. Once he reunites with her, Ash was pleased to hear that Iris is the new champion of Unova, which shows how strong their friendship still is, and participating in the World Coronation Series. Ash and Iris had their battle where he emerge victorious in the World Coronation Series then they both agree to battle again one day. Also, Ash was surprised that Iris was in the Master Class in the World Coronation Series.
Ash and Cilan are close friends. Also, Ash greatly respects Cilan as a Pokémon Connoisseur and as a Gym Leader. Much like his relationship with Brock, Ash enjoys Cilan's cooking and doesn't usually fight with him, but when they do, they make up right away. In addition, Ash would be helped by Cilan as he helps him see through his mistakes. Before going their separate ways, Ash was told by Cilan how much he learned from him. Pleased, Ash said he felt the same way about him. Although, Ash and Cilan friendship will remain no matter where their journeys take them.
Clemont is one of Ash's best friends. Like with Iris, they practiced battles with one another during their journey. While Ash respects Clemont as a Gym Leader, he also admires his inventions and cooking. Like with Brock, Tracey, Max and Cilan, Ash and Clemont rarely fought. On the other side, Ash would be looked out by Clemont, as he would sometimes warn him about impending danger. Ash trusts Clemont to know about his Bond Phenomenon ability. After their journey concluded together, Ash went back home to resume his journey while Clemont stayed to run his gym with Bonnie right beside him. However, Ash and Clemont knew that they'll always be friends no matter where they are, which was confirmed by a briefly reunion.
Ash and Bonnie are very good friends. They both have a great love for Pokémon, and Ash cares for Bonnie like a little sister. Like with Max, Ash is protective of Bonnie and would do anything to keep her safe from danger. They both like to have fun with Pokémon and do related activities with them as well. Like with his male companions, Ash hardly had any arguments with Bonnie. Ash knows that Bonnie will keep his Bond Phenomenon ability a secret. When their journey together ended, Ash and Bonnie went their separate ways as he went home to find out his next move as a Trainer while she stayed in Kalos alongside Clemont. Ash also knows that he'll always be friends with Bonnie, which was confirmed by a briefly reunion.
Serena is Ash's childhood friend, though they had an estranged relationship due to being separated for many years. They first met many years ago at Professor Oak's summer camp, where Ash helped Serena with a knee injury that she received when she got spooked by a Poliwag, tripping and skinning her knee. Ash and Serena were separated for many years until she eventually saw the boy on TV one day. Rushing to Santalune City to meet her savior, Serena was initially disappointed to find out that Ash didn't recognize her at first. When he planned to go to his next Gym, Ash asked Serena what she was going to do next, though seeing that she was unsure he asked her if she wanted to travel with him and the group, an offer that she happily accepted. However, after being shown the handkerchief he used on her knee back at Professor Oak's camp, Ash remembered meeting Serena when he was little, calling her the "girl with the straw hat." Although their friendship was mended, Ash's relationship with Serena grew to a close friendship as they would give each other helpful advice and supported each other during their long journey through Kalos.
Ash was clueless to Serena's very strong crush on him during their journey, which she never denied her feelings for when asked or confronted as she would become initially embarrassed and tried to keep it a secret. Much like his relationship with Dawn, Ash hardly has any disagreements with Serena, and the two are never judgmental of each other. However, their friendship is taken to the next level as Ash doesn't immediately annoy Serena with his antics. Serena herself even goes the extra mile in that even when scolding Ash, she's much gentler and doesn't show nor conceal her temper towards him, hinting that she knows some appropriate ways to be firm whilst keeping her cool. Despite all this, however, they did have a fallout with each other when Ash snapped at Serena for not understanding his feelings, after initially losing a Gym battle for his last Kalos badge. This fight wasn't entirely an argument though like with most of Ash's previous female companions as Serena was only trying to help him snap out of his depression. As such, after realizing that she was just trying to help, Ash felt guilty for being so hard on Serena, who in turn, felt guilty believing that she made the scene worse by yelling back at him and that he was out in the blizzard as a result of their argument. As Serena attempted to apologize to him for lashing back, Ash stopped her to show how truly sorry he was for hurting her by thanking her for talking and knocking, due to being thrown a couple of snowballs, some sense into him.
Ash has faith in Serena as he trusts her to keep his Bond Phenomenon power hidden from anyone that isn't their friend. Before going their separate ways, Ash was pleased when Serena said that she was glad that she came with him and that he was going to like the person she grows into the next time they see each other. However, Ash became stunned when Serena leaned forward and kissed him, shocking all of their friends. Also, Ash knows his friendship with Serena will remain strong even when they are apart, which was shown when he briefly reunited with her in Hoenn.
Ash and Lana share a close friendship since they were classmates at the Pokémon School in Alola. However, although they're friends, Ash gets annoyed with Lana's jokes at times, but never truly had any disagreements with her. During Ash's time in Alola, he and Lana went on adventures together, although they were sometimes joined by Mallow. Ash and Lana would also help each other in various tasks or provide assistance whenever their Pokémon were separated from them. Ash appreciates Lana support in becoming the first Champion of Alola. However, Ash and Lana went their separate ways as he decided to return home to continue his journey while she stayed in Alola to go fishing for Manaphy with her dad. Although, they remained friends until the end, shown when he briefly revisited Alola a couple of times.
Ash and Lillie are best friends as they were classmates at the Pokémon School. During their time in Alola, they were often there to help cheer each other up whenever one of them was feeling down. Like with Max and Bonnie, Ash would go through great lengths to protect Lillie from danger. Ash was a big help for Lillie as he never gave up on her and helped her with many things, including getting through her fear of touching Pokémon. Also, Ash helped Lillie and Gladion save their friends and Lusamine from Ultra Space, earning her appreciation even more. In addition, Ash and Lillie share a lot of things in common, including a strong love for Pokémon, excitement about going on adventures, meeting new Pokémon, and a willingness to help others.
Like what he did for Serena, Ash gave Lillie good advice as he helped her perfect her Z-Moves, although she didn't get what meant at first, and supported her. They both didn't have any disagreements as Ash would stand up for Lillie and she has done the same for him. Also, Ash was very happy that Lillie supported him in becoming Champion of Alola. Ash and Lillie parted ways when he decided to continue his own journey while she left to go on a journey to find her long lost father. However, they gave each other thanks for everything they did for one another. Despite being apart, Ash knows his friendship with Lillie will always be with him. Also, during a visit in Alola, Ash was happy that Lillie was doing ok on her journey to find her father and hopes to see her again as she hopes the same for him.
Ash ends up reuniting with Lillie in Galar as he rushed to her defenses when a Shiny Nihilego was going to attack her. Also, Ash helped Lillie in getting her father to remember his family, after finding out that he lost his memory in the accident that separated her family for a very long time. Ash even accompanied Lillie and her family back to Alola.
Sophocles is one of Ash's closest friends since they were former classmates at the Pokémon School. They encourage and support each other as they provide assistance to each other whenever they need it. Although, Ash and Sophocles could disagree at times but get over it quickly. Like how he acted with Clemont, Ash is impressed with Sophocles' know how and his inventions. One special gift that Ash gave to Sophocles was a Charjabug initially meant to be a farewell gift.
After becoming Champion of Alola, Ash was very happy that Sophocles supported him till the end. Ash and Sophocles parted ways when he decided to return to Kanto in order to resume his journey and the latter left for Hoenn. However, Ash and Sophocles both know that their friendship will always be there no matter where they are, shown when they briefly reunited when he visited Alola a couple of times and he meet up with him in Hoenn.
Ash and Mallow are close friends since they were also classmates at the Pokémon School. Like Brock and Cilan, Ash is impressed with Mallow's cooking. During their time in Alola, Ash and Mallow went on adventures together, sometimes they had Lana accompany them. They are often there to support and assist each other whenever they need it. Ash and Mallow hardly ever had any arguments with each other. Also, Ash greatly appreciates Mallow support in becoming Champion of Alola. They went their separate ways when Ash decided to continue his journey while Mallow stayed in Alola to make her family restaurant a place for both people and Pokémon. However, they remained friends even though they were apart. During a visit from Alola, Ash was pleased that Mallow wanted to celebrate his visit and meeting his new friend, Goh. Also, Ash got to see Mallow again during another visit in Alola.
While attending the Pokémon School, Ash resided at Professor Kukui's house. The two have an extremely strong, almost familial bond. In fact, their relationship is almost akin to a father and son, since they spent a lot of time together outside of the Pokémon School and enjoy each other's company. At times, Professor Kukui scolds Ash like a parent whenever he does something wrong, especially when he wonders off on his own but he does soften a couple of times as he understands that his reasons were to help his or wild Pokémon whenever they were in trouble. They even have a student/mentor relationship with each other that works two ways, since Kukui is his teacher in the school and Ash became a mentor to him when he unexpectedly ended up going back in time to when he was five years old. In the Poké Problem segment called A Timeless Encounter, Professor Burnet commented on how Ash and Kukui were like brothers when they ate their food.
Also, Ash admires Kukui's alter ego, the Masked Royal, and gets fired up when watching his matches on TV with his Pokémon and Professor Burnet since they are also huge fans of his. After battling him twice and being defeated both times, Ash was told by the Masked Royal that his Incineroar and Ash's Incineroar, during his time as a Torracat, were officially rivals. When fighting as the Double Royals, their battling coordination and teamwork were so good that James said, "Those two are so in sync, you'll never know it's their first time." After the grudge match against The Revengers, Ash asked the Masked Royal to have a final battle with him someday, which he accepted. Ash was very happy that Professor Kukui watched him become Champion of Alola. After finding out his identity, Ash was shocked that the Masked Royal and Professor Kukui were the same person at first. However, Ash became excited about it since he didn't care about how long Professor Kukui kept his secret. Ash and Kukui eventually had to part ways when he decided to return to Kanto, but their bond remained intact. Also, like with Professor Oak, Ash trusts Professor Kukui to look after his Pokémon alongside his wife and will always consider him the father that he never had.
Ever since Professor Burnet married Kukui and moved in with Ash, she has acted as a mother figure to the boy. Although, unlike Delia sometimes, Ash doesn't get embarrassed by Professor Burnet as she usually doesn't say anything that would freak him out or nervous. They are both huge fans of the Masked Royal, although they were both clueless at first that it was actually Professor Kukui along with Ash's classmates. However, Ash, his classmates, and Professor Burnet eventually found out about the Masked Royal's identity, which ended up just making them admire him even more. Ash even appreciates Professor Burnet support in becoming Champion of Alola. Before going back home to resume his journey, Ash thanked Professor Burnet for everything, knowing they'd always be friends no matter the distance. Also, Ash not only knows his Pokémon are in good hands with Professor Burnet alongside her husband but will also consider her another mother.
When Ash first met Chloe, she was very shy as she often is with new acquaintances. She seemed rather suspicious of Ash and quickly shuffled away without talking to him. This suspicion was probably made stronger because of her father's Yamper electrocuting him. For some time onward, despite Ash's nice and friendly nature, Chloe would often freeze up whenever he spoke to her. However, Ash has been able to get Chloe to trust him more as she has got to know him better and they formed a friendship with each other. Chloe even helped Ash patch things up between him and Pikachu, who had become lonely and jealous about the time his partner was spending over training Riolu instead of him.
Ash first met Goh when they jumped on Lugia at the same time. During and after their adventure with the Legendary Pokémon, the two boys found out they had a lot in common and instantly formed a very strong friendship with each other. Ash would help Goh whenever he needed it and he would do the same for him. Despite their friendship, Ash and Goh do clash at times, but manage to makeup in the end. Much like how he was with Misty and Kiawe, Ash can be competitive with Goh at times. Ash even helps Goh understand that some of his traits need fixing since he shares some of the same traits that he once had. Like he did for May, Dawn, Serena and Lillie, Ash acts like a mentor to Goh and helps him in various ways as a Pokémon Trainer. Also, similar to what Brock and Cilan did for him, Ash helps Goh see through his mistakes from time to time.
Sometime later, Goh finds out that Ash is the Pokémon Champion of the Alola region, which not only surprises him but also excitingly asked him as to why he didn't tell him about his Champion status earlier and he humbly answered that he forgot to say something about it.
Although he heard about him through the professors, Ash officially meets Lei during a visit to Alola while reuniting with Professor Burnet and Professor Kukui. Lei was very excited to meet Ash, seeing him as a big brother figure.
Ash and Gary have known each other since they were little, as they grew up together. Ash and Gary had a close friendship, but it ended when they became rivals and started their Pokémon journeys. Despite their rivalry, Ash and Gary still looked out for each other at times, showing that they were still friends.
During their time in Johto, Ash and Gary were able to mend their friendship, as they grew close to one another again. Although Gary moved on to become a researcher like his grandfather and Ash continued his Pokémon journey, they remained friends, although they still have a bit of a friendly rivalry with each other. Ash gets annoyed when Gary teases him from time to time, but it's all in good fun.
Ash is close friends with Kiawe. They were classmates and training partners for Pokémon battles at the Pokémon School in Alola. While they're usually on good terms, Ash and Kiawe also share a friendly rivalry with each other. Much like how he was with Misty, Ash is also competitive with Kiawe from time to time as they do sometimes argue, though they get over their disagreements quickly. Despite their rivalry and competitiveness, the two boys are always ready to lend a hand to each other. Also, Ash liked that Kiawe had faith in him when he became Champion of Alola. Ash and Kiawe eventually went their separate ways as he decided to go back home to resume his journey while the latter stayed in Alola to resume his Island Challenge. Despite being apart, Ash and Kiawe both knew that they'll always friends, shown when they briefly reunited when he came to visit Alola a couple of times.
Pikachu is Ash's starter Pokémon, partner, and best friend, even though there are times that they don't agree with each other. Despite they had a rough start at first, they became nearly inseparable. Pikachu has always been on Ash's side during his journey. In addition, Ash always allows Pikachu to ride on his head or shoulder during his journey, since he knows that his partner doesn't like to stay inside his Poké Ball. They protect each other from trouble and would stand up for each other. A lot of people see that they're perfect partners.
Despite their friendship, Ash does butt heads with Pikachu at times but they don't stay that way for long. Whenever Pikachu fell victim to someone's control, Ash would always help him and give him enough encouragement to break free from it, although he was successful a couple of times but there have been times the control would be too strong for him to break free from but he never gives up on getting through to his best friend no matter how tough the hold was on him. Also, when the other way around occurs, Ash was given the strength to break free from someone's control when he would hear Pikachu's voice calling out to him, which shows how strong their friendship for one another is. Ash even trusts Pikachu greatly as he knows he'll keep both his Aura and Bond Phenomenon abilities a secret.
Rotom is not only a companion to Ash who gives information about Pokémon and advice during his time in Alola but is also his very good friend. Whenever it was needed, Ash would go to Rotom for help and it would go to him for the same reason. Also, Ash appreciates Rotom support in becoming Champion of Alola. Ash and Rotom went their separate ways when he decided to continue his journey while the latter stay in Alola to work for the Aether Foundation. Despite being apart, Ash knows his friendship with Rotom will remain no matter how far they are from each other, shown when he came to visit Alola.
When he was a little boy, Ash went looking for Pokémon in the forest. However, Ash got lost and it was frightened to a point of tears. When it started to rain, Ash was forced to take shelter under a hollow tree. While under the tree, Ash noticed a group of Pokémon who were also seeking shelter from the rain. Ash invited the Pokémon inside the tree where they kept him safe and warm. This made Ash so happy that he wondered how much he wanted to become a Trainer to travel the entire world with his Pokémon friends.
Later on, Ash shows his mother a poster of Professor Oak's Pokémon summer camp that he wanted to go to and she happily signed him up. However, Ash overslept and miss the summer camp. After that, Ash went home, hoping he would go next time.
Sometime later, Ash successfully enrolled in another one of Professor Oak's Pokémon Summer Camp where he would learn the basics of Pokémon and being a Trainer when he gets older. While looking for a Poliwag, Ash happened upon a young girl and fellow camper named Serena who got lost in the forest while looking for her group. Seeing that she injured her knee when a Poliwag startled her, Ash wrapped a clean blue handkerchief with a Poké Ball on each corner around her wounded knee to brace it. Ash lent her his hand and helped her up when she couldn't get herself up due to the pain. While doing so, Ash even hugged her then he guided her out of the forest and took her back to the campsite.
At some point before starting their journeys, Ash was friends with Gary Oak, Professor Oak's grandson, as they would go to the movies together when they were younger. Then one day, Ash and Gary both fished out a Poké Ball on both of their fishing lines. After arguing about who keeps it, Ash and Gary both broke the Poké Ball into two pieces where they kept one half of it as a reminder of that day.

Ash's Japanese name, Satoshi, comes from Satoshi Tajiri, the creator of Pokémon. Ash comes from the middle option of default sample names from the in-game player file configuration screens at the start of the journey (which is the option where Satoshi was listed in the original Japanese game) and his last name, Ketchum, comes from the phrase "Gotta catch 'em all".
- Ash's original Japanese name is "Satoshi" and he was named after and based on Satoshi Tajiri, the creator of Pokémon.
- Ash's last name, Ketchum, may be derived from "catch 'em".
- His fake name, Tom Ato, might be derived from his last name, Ketchum, and be related to Ketchup.
- Ash's name is based on one of the three options for one's name in Red/Blue/Yellow.
- In the 20th Pokémon movie as well as Betrayed, Bothered, and Beleaguered!, Ash's birthdate is confirmed to be the same day he began his journey.
- On a related note, Ash is still considered 10 years old in promotional materials as well as the first episode of Black & White (dub only) despite the episode "Best Wishes Until We Meet Again!" strongly implying that at least a full year had passed since his time in Johto. Also, in the "Pikachu & Pichu" short, which aired at least two full series before Best Wishes, it is stated a full year has passed since Ash and Pikachu first met then, as well. Though he is still officially "10", this would make Ash chronologically around 12, or, around 12–13. Takeshi Shudo also wrote the screenplay for the movie "The Spell of the Unown", which the Pikachu & Pichu short was originally shown with.
- Besides the Orange League and Kanto Battle Frontier, the Alola League is currently the only actual league tournament that Ash ever won.
- In the Kanto region, Ash often turned his cap backward when preparing for a battle or to capture a Pokémon. This habit wore off as time went on. However, he was shown turning his cap backward when he was battling Tobias, presumably because Tobias was arguably the strongest Trainer he'd ever faced, being the only one who was capable of beating all six of his Pokémon using only two of his own. Although in the Best Wishes series, Ash is seen turning his cap backward more often. He recently turned his hat around in A Battle of Aerial Mobility! when he used Froakie to help defeat and capture Fletchling.
- In Tekken 6, there is a female character named Eleonore "Leo" Kliesen, who can be customized to look like Ash Ketchum. Coincidentally, both characters were voiced by Veronica Taylor and sounded very similar. However, in Tekken Tag Tournament 2 and onwards, Leo's voice grunts are used in later games where it was performed by Veronica Taylor, and Leo is now voiced by a German voice actor to speak in her native German language.
- According to "Climbing the Walls!", Ash's favorite move is Thunderbolt, mostly since this is his Pikachu's most notable move throughout the entire series.
- Ash was Veronica Taylor's favorite role to voice in her career.
- Ash has a total of 82 Pokémon under his ownership, including all 30 of his Tauros.
- Ash is the first male character to:
- Have a different Pokémon as his Starter Pokémon that isn't an actual Starter Pokémon from the normal Grass/Fire/Water-mix
- Have caught or received a Pokémon that has evolved into its second stage or was fully evolved prior to meeting their Trainer.
- Have caught at least one Pokémon of every type.
- Have caught at least one Pokémon species from all eight core series regions.
- Have caught a regional Starter, Artificial, a Male-only and Shiny Pokémon.
- Have caught more than one regional Starter Pokémon as he caught one or more from the 7 mainline Regions, except Galar.
- Have caught a Pokémon with a unique power or form.
- Have caught an Ultra Beast.
- Have compete in 7 Regional Pokémon League Conferences.
- Have used four battle techniques, Z-Moves, Gigantamax, Mega Evolution, and Dynamax.
- Have defeated more than one Legendary or Mythical Pokémon.
- Have looked after both a Mythical and Legendary Pokémon.
- Become an official regional Pokémon Champion after winning a Regional Pokémon League Conference in Alola.
- Have use a move from all eighteen types of Pokémon.
- So far, Ash has:
- Fourteen out of eighteen different types of Pokémon that fully evolved, although he has four of the missing types but all of them have already evolved into their second stage or was fully evolved prior to meeting their Trainer.
- Thirteen out of eighteen that are or were pure types, although he has the missing types but are all dual types.
- Not caught a Female-only and Legendary Pokémon.
- Ash has been held captive and used as a hostage for almost every villainous organizations in each Region he's been to:
- Ash has obtained at least one Flying-type from each region he has traveled.
- In the first episode of Pokémon Journeys, Ash overslept and was late to go to Professor Oak's summer camping trip just like the first day he was going to get his first starter Pokémon in the first episode of the original series "Pokémon - I Choose You!".
- Ash has his own special day event known as "National Ash Ketchum Day", which commemorates his first Pokémon League victory in Alola. It has been celebrated every September 15 since 2020.
- Just as Iris and May captured all of her Pokémon without battling them, Ash also caught his Pokémon from the Alola Region without having a Pokémon battle.
