Ash Ketchum

"I choose you!"

- Ash's catchphrase when summoning a Pokémon

Ash Ketchum is the main protagonist of the Pokémon anime series who has always dreamed of becoming a Pokémon Master. As soon as he turned ten years old, he rushed to Professor Oak's Laboratory to get his first Pokémon. He is the first human character to be introduced in the series. Originally wanting to choose Squirtle, Ash ended up receiving the Pokémon Pikachu, as he arrived late leaving him with no other starters to choose from. He sets onto his adventure later in the day. He is currently also the only character shown to have been to all of the regions.

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, Ash attempted to save Pikachu from them; seeing Ash so determined to help him, Pikachu protected Ash from the Spearow by electrocuting the entire flock, thanks to being struck by lightning at that exact moment, supercharging his Electric-type move. From then on, Pikachu and Ash became best friends forever. As an unskilled trainer, Ash started his adventure while meeting his friends Misty, Brock, and capturing new Pokémon.

Ash eventually defeated all the Gym Leaders in Kanto, allowing him to enter in the Pokémon League. Since then, he has continued to travel, journeying through the various regions, making new friends such as Tracey, May, Max, Dawn, Iris, Cilan, Clemont, Bonnie, and meeting his childhood friend Serena, challenging all the Gym Leaders, entering each region's Pokémon League 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. Ash is currently attending Pokémon School in the Alola region, with his new friends Lillie, Mallow, Lana, Sophocles and Kiawe.

Appearance
Ash wears a few outfits, as seen in the Pokémon anime, he also has black hair and brown eyes, and always wears a cap. Over the past regions, he had different caps.

Ash has two lighting bolts-like markings underneath each eye.

Ash has a narrow, triangular, edgy, tuft of hair in the middle of his forehead, that come to point on the right side. Without the cap, Ash has a cowlick.

Ash's pupils were not visible during the "Indigo League" through the "Diamond and Peal series", until the "Black and White series" showed them.

Original series
In the original series, Ash wears a white and blue short-sleeved jacket with gold trim, white collar and sleeves, a dark teal T-shirt, blue jeans with light blue cuffs, black and white sneakers with red dots, green fingerless gloves with light green borders and a red and white cap with a green stylized "L".

In the XY series, Ash wears yet another new outfit, consisting of a blue collared shirt with short sleeves and white trim, black undershirt, darker blue jeans, a red and white hat, and red high top sneakers.

In the Sun & Moon series, Ash wears a new outfit different from his previous outfits.

His hat is red, dark blue and gray and the Poké Ball design is white. Ash wears a silver Z-Ring on his left wrist which was later changed into a black Z-Power Ring. Unlike the other region clothes, he doesn't wear any fingerless gloves.

Personality
Ash is very determined to be a good Pokémon trainer as seen in every episode. He shows a lot of sympathy towards Pokémon, usually helping and befriending Pokémon he meets on his long journey. He doesn't like trainers who mistreat Pokémon such as Damian and Shamus. He is a role model to many people such as May, Dawn, N, and Serena. Ash's strategy is problem solving a Pokémon battle, including thinking on his feet during a special match. His tactics throughout many episodes involves problem solving battle issues and anything that relates to the Pokémon's special abilities. Even having inputs from his friends has helped Ash whenever he's stuck in a jam. Ash is generally kind, compassionate, and brave, but can be stubborn, hot-headed, short-tempered, impatient, cocky, reckless, and impulsive at times.

Ash does fear losing anyone he's really close to, his friends and family, but fears losing his Pokémon family even more, due to the many times Team Rocket try to steal his Pokémon, also he fears of putting everyone he cares about endanger. Also, Ash fears that his Pokémon would leave him the way Pikachu almost did to him, after Team Rocket tried turning Pikachu against him when he had amnesia in the Ruby and Sapphire, Advanced Challenge, series but didn't hold any grudge against his best friend due to knowing that it wasn't his fault, but the other reason why he fears his Pokémon would leave him is that he didn't meet their expectation or wasn't strong enough for them. Because of his fears, Ash sometimes doubts his Pokémon potential which also effects his faith and trust in them as well, especially when some of them display a unique kind of power in their strengths, shown in the Diamond and Pearl series, Battle Dimension and Sinnoh League Victors, with his Infernape Blaze ability also this was shown in the XYZ series with his Greninja Ash-Greninja form and in the Sun and Moon, Ultra Adventures, series when his Lycanroc goes into a red eye state. Ash almost lost himself because of his fears, shown in the XYZ series, if not for one of his friends, Serena, helping him get back on the right track and being reminded about why he wanted to become a Pokémon Master. However, Ash does put fear aside to help his Pokémon become stronger which slowly helps him get over his fears also because of it he was able to help the ones with a rare ability perfect their true power.

Since entering the Kalos region, Ash has demonstrated much greater maturity and level-headiness; both in and out of battles as he continues his journey to be a Pokémon Master. So far, the only Pokémon League he has won is the Orange League in the Orange Archipelago. Since entering the Alola region, Ash is shown to be far more enthusiastic than he did in the Kalos region, while at the same time kept his determination and his love for Pokémon.

Ash has a strong sense of justice to assist Officer Jenny, the Pokémon Rangers and the Police for their mission. He hated all source of evil organizations, such as Team Rocket, Team Aqua, Team Magma, Team Galactic, Team Plasma, Team Flare and Team Skull, and Pokémon Poachers, such as Captain Crook, Iron-Masked Marauder, Rico, J and other poachers, because they steal Pokémon from people or the wild and would do bad stuff to them. He would risk his own life to protect Pokémon and defeat criminals to put an end to their schemes.

Ash enjoys having Gym battles against Gym Leaders to earn Gym Badges to participate the Pokémon League. Ash also has gone to the Battle Frontier to battle Frontier Brains for Symbols. In Alola, Ash decided to participate the Trials to earn Z-Crystals to use Z-Moves.

Skills
Ash has shown be quite athletic, he can run, swing on vines, carry some heavy stuff, swim and is very good climber, shown in the show many times also it was shown in Pokémon 4Ever and in Lucario and the Mystery of Mew. Ash can take on a Pokémon attack for a long period of time without taking too much damage, depending on the attack. Ash has grown to be an amazing battler also he has some performing skills, due to competing in a couple of Pokémon Contests also from watching May and Dawn. Ash does have good fishing skills and some cooking skills, due to spending a lot of time around friends who can cook.

Ash has the ability to sense and control Aura, as it was shown in Lucario and the Mystery of Mew and once again in the Diamond and Pearl episodes, Pokémon Ranger and the Kidnapped Riolu! (Part 1) and Pokémon Ranger and the Kidnapped Riolu! (Part 2). Aaron's Lucario has stated that Ash's aura is the same as Aaron's, and Ash was able to use his aura to find and save Riolu. Ash only used his aura abilities when it has something to do with either Riolu or Lucario.

Also, Ash has the ability to use Bond Phenomenon, shown in the XYZ series, with one of his Pokémon, Greninja. Ash also has demonstrated great skills in utilizing Z-Moves as shown in the Sun & Moon series, and even create his own Z-Crystal, the Pikashunium Z, and preform a exclusive Z-Move with one of his Pokémon, Pikachu which is 10,000,000 Volt Thunderbolt.

Ash sometimes displays the ability to understand the feelings of Pokémon, due to spending a lot of time around them. Also, Ash does sometimes displays the ability of sharing a connection with some of the Mythical or Legendary Pokémon as they chose to connect with him out of caring for them and for his strong will power to protect them, shown when Azelf chose to connect with him in the Diamond and Pearl series, Battle Dimension and Galactic Battles, and when Victini linked up with him in the movie Black/White Victini and Zekrom/Reshiram. When he's has that connection to the Mythical or Legendary Pokémon he can feel the pain they are in, sense they have been captured, see their thoughts and memories along with contacting him or appearing to him in his dreams as a way of asking for his help or to show him the danger they're all gonna be in also as a way of asking him to do something for them, shown with Azelf, Victini, Solgaleo and Lunala.

Delia Ketchum
Ash cares very much about his mother but gets annoyed when she embarrasses him. When Delia got kidnapped in Pokémon The Movie 3, Ash went through get lengths to get his mother back. Ash does appreciate when his mother comments how much he has grown as a person and as a Pokémon Trainer. Also, Ash is very grateful that his mother supports him whenever he gets ready to go on another journey.

Professor Oak
Ash has known Professor Oak since he was little as he's a family friend and respects him as a researcher. Also, Ash would go to Professor Oak for advice and would call him whenever he needed one of his Pokémon that has been kept in storage.

Gary Oak
Ash and Gary have known each other since they were little as they grew up together. Ash and Gary had a close friendship. However, their friendship ended when they became rivals and started their Pokémon journeys. Despite their rivalry, Ash and Gary at times still looked out for each other, 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. Ever since Gary moved on to become a researcher like his grandfather and Ash continued his Pokémon journey, they remained friends till the end even though they have more of a friendly rivalry with each other. Ash gets annoyed when Gary teases him from time to time.

Pikachu
Pikachu is Ash's Starter Pokémon, partner and best friend; even though they had a rough start at first, they are nearly inseparable. Pikachu always been on Ash's side during his journey. 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.

Misty
When Ash first met Misty they didn't get off on the right foot with one another, after he borrowed her bike to save his Pikachu's life which got accidentally destroyed by Pikachu's thundershock attack. At first, Ash didn't want Misty around and disliked that she kept following him as she was gonna follow him until he payed her back for her bike that he accidentally destroyed. However, Ash changed his opinion about Misty as she became a mentor to him and helped him become a great Pokémon Trainer. Also, Ash grew to care for Misty and became best friends with her. Ash would always have Misty's back just like she has his. After their travels in Kanto, Ash and Misty traveled through the Orange Islands and Johto together. Also, Ash and Misty have a friendly rivalry with each other as they even tease each other from time to time. Ash and Misty have their fights, although some of them almost destroyed their friendship, but they manage to patch things up in the end. After their journey through Johto, Ash and Misty part ways when she was forced to run the Cerulean Gym while her sisters went on an around world cruise as she also got her bike back as well. Despite no longer traveling together, Ash and Misty, who decided to run the Cerulean Gym full time, maintain their strong friendship for one another.

Brock
Ash and Brock are best friends as they traveled together in Kanto. When Brock stayed with Professor Ivy for awhile, Ash was bumped but understood his reasons. After his best friend return, Ash and Brock traveled together from Johto through Sinnoh. Through their travels, Ash grew to consider Brock like a big brother figure to him and was one of his mentors as he would give him helpful advice to better himself as a Trainer. Ash and Brock are always there for each other. They don't usually fight with one another but they had small fallout but makeup pretty quickly. Ash and Brock almost lost their friendship once when one of Team Rocket's tricks got out of hand but they mend it when the truth came clear. In addition, Ash and Brock would have practice battles together. They officially parted ways after their travels in Sinnoh when Brock decided to become a Pokémon Doctor and Ash continued traveling to fulfill his ambitions. After going their separates ways, Ash and Brock maintain their lasting friendships with one another.

Tracey
Ash and Tracey are pretty close friends as they traveled together through the Orange Islands. Also, Ash and Tracey have great respect for each other. They part ways from traveling when Tracey became Professor Oak's assistant and Ash continue traveling but they see each other sometimes when he come to visit Pallet Town.

May
May is one of Ash's best friends as they traveled through Hoenn and Battle Frontier together. When May chose to become a Pokémon Coordinator, Ash gave her his full support and helped her in anyway he can for her. Also, Ash became a mentor to May and guided her in the ways of a Pokémon Trainer. They would train together for Ash's battles and for May's contests. Ash and May have their fights but they make amends with each other in the end. Their friendship remain, after going their separates ways.

Max
Ash and Max share a common love for Pokémon as they like to do their own thing while May and Brock went shopping in towns and cities when they were traveling through Hoenn and Battle Frontier. They're each other's best friend as Ash acts like a big brother figure towards Max. Ash would protect and keep Max safe from danger. When Max was going to return to Hoenn while May traveled through Johto, Ash promised one of his best friends that when he becomes a Pokémon Trainer that they were gonna have a battle together.

Dawn
Ash shares an unbreakable friendship with Dawn and would high five her whenever something good happens for them or as a sign of their friendship. Sometimes, Ash would fight with Dawn a little at times but they easily makeup. Ash would stand up for Dawn and she has done the same for him. Like he did for May, Ash mentor Dawn in the ways of a Pokémon Trainer and helped her as a Pokémon Coordinator. Also, Ash supports Dawn and cheers her on during her Contests as she cheers him on during his Gym Battles. Ash and Dawn would have practice battles to help their skill level. After they went their separate ways, Ash and Dawn remain best friends.

Iris
Much like his relationship with Misty, Ash does get into fights with Iris and they do tease each other from time to time as he gets annoyed when she calls him a little kid. However, Ash and Iris are very good friends as they do have respect for each others skills and the love they have for Pokémon. Also, Ash and Iris would train for battles together.

Serena is one of Ash's closest friends as they first meet when they were little. At first, Ash didn't remember his encounter with Serena but seeing the handkerchief he used to mend her injury when they were little, after she trips and hurt herself when a Poliwag startled her, is when he remembered their meeting in Pallet Town. Ash would give helpful advice to Serena and supports her. Also, Ash would help Serena whenever she needed it and she has done the same for him. When Serena went looking for Ash, after he lost his first attempt to get his last badge to enter the Kalos League, they ended up having an argument, although it wasn't entirely a disagreement as she was just trying to help him get over his depression. Ash nearly lost himself if not for Serena reminding him of who he is as she told him how the friend she knows is full of energy, a leader, always tries his best, he stays positive, he never gives up and he hangs in there until the very end. After snapping out of his depression, Ash did show Serena how truly sorry he was for lashing out at her by thanking her for talking and knocking some sense into him. Also, Ash was very oblivious about Serena's crush on him. Before going their separate ways, Ash felt happy when Serena told him how glad she was that she came with him and that she admired him a whole lot. Ash hears Serena say that she is gonna be a more amazing person for him when they cross paths again then was given a kiss which got him to realize that she had feelings for him and was thanked for everything he did for her.

Lana
Ash and Lana share a close friendship as they are also classmates at the Pokémon School. Also, Ash gets annoyed with Lana's jokes but gets more annoyed when he falls for it.

Lillie
Ash and Lillie are each other's best friend as they are also classmates at the Pokémon School. Ash is often there to cheer Lillie up whenever she is down and she does the same for him. Like he would for Max and Bonnie, Ash would go to great lengths to protect Lillie from danger and does get concern for her safety. Ash is the biggest help for Lillie as he never gave up on helping her get over her fear of touching Pokémon. Also, Ash helped Lillie and her brother save their mother from Ultra Space along with their other friends as well. Ash even helped Lillie perfect her Z-Moves as he gave her some advice on how it feels to use one, although she didn't get it at first but got it when she did it. In addition, Ash and Lillie share a lot of things in common such as a strong love for Pokémon, excitement about going on an adventure and a willingness to help others for various reasons.

Sophocles

Ash and Mallow go on adventures together and are sometimes joined by Lana. Ash is often there to assist Mallow whenever she needs it and they often support each other.

Professor Kukui
While attending the Pokémon School, Ash resides at Professor Kukui's house. The two appear to have a father and son like relationship as they spend a lot of time together outside of the Pokémon School. They even have a student/mentor relationship with each other that works two ways since Kukui is Ash's teacher in school and Ash was a mentor to Kukui when he unexpectedly ended up going back in time to when Kukui was five years old. In the Poképroblem segment of SM125, Professor Burnet comments on how Ash and Kukui were like brothers when they were eating the food. Ash admires Kukui's alter ego, the Masked Royal as he gets fired up when watching his matches on the TV with his Pokémon and Professor Burnet as they are huge fans of his. After battling him twice and being defeated, the Masked Royal states that his Incineroar and Ash's Torracat are rivals. When fighting as the double royals, their battling coordination and teamwork was well noticed as James commentated "Those two are so in sync, you'll never know its their first time". After the grudge match against The Revengers, Ash asks the Masked Royal to have a final battle with him someday.

Rotom
Rotom is not only a companion to Ash who gives information about Pokémon and advice 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.

Professor Burnet
Like his mother Delia, Burnet acts like a mother figure to Ash, ever since she got married to Kukui and moved in with them. Also, Ash and Professor Burnet are huge fans of the Masked Royal, although they're both clueless that it's Professor Kukui, along with their friends, Ash's classmates.

Pre-series
When he was a little boy, Ash went on a field trip. However, Ash ended up getting separated from his group during his field trip. Frightened to a point of tears, Ash was forced to take shelter under a hollow tree when it started to rain. However, 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. Sometime later, Ash enrolled in 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.

Design
Ash's design is based on the player character from Generation I, Red.

Etymology
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".

Trivia

 * Ash's Japanese name is Satoshi. He was named after and based on Satoshi Tajiri, the creator of Pokémon.
 * In the 20th Pokémon movie as well as previously in the anime, 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 Best Wishes 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, also if including his age in Takeshi Shudo's novelization. Takeshi Shudo also wrote the screenplay for the movie "The Spell of the Unown", which the Pikachu & Pichu short was originally shown with).
 * Ash turned 11 in the Sun and Moon anime.
 * Ash is the only human character to appear in every episode and season.
 * Ash has a total of 49 Pokémon including different evolutionary forms (78 if all Tauros are included).
 * Ash has caught at least one of the Starter Pokémon in every region.
 * Ash was originally going to have a Clefairy instead of a Pikachu as his partner. This was changed because people found Pikachu to be cuter.
 * Beside the Orange League and Kanto Battle Frontier, the Alola league is the only league tournament that Ash ever won..
 * Ash is the only known trainer to have ever defeated Tobias' Darkrai.
 * In the Kanto region, Ash often turned his cap backwards 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 backwards 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 backwards more often.
