Ash Ketchum/XY

A trainer from Pallet Town, aspiring to become a Pokémon Master, Ash Ketchum is a main character of the Pokémon Anime.

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

Personality
Ash still has some of his childish excitement, but he also demonstrated much greater maturity and level-headiness since entering the Kalos region, both in battles and out. He's even more open to advice from others.

Season 17: XY
Ash traveled to the Kalos region to compete in the Kalos League and to continue his dream of becoming a Pokémon Master. He gained new traveling companions in the siblings Clemont and Bonnie and later reunited with his childhood friend Serena, who still remembered Ash rescuing her a long time ago and would travel with him as well. Despite being childhood friends with Serena, he had no memory of their relationship until Serena showed him the handkerchief he used to mend her knee when they were little kids in the episode, Giving Chase at the Rhyhorn Race!. Ash also caught five new Pokémon: his first Kalos capture was a Froakie followed by a Fletchling, Hawlucha, Goomy and Noibat.

Within the first five episodes of the season, Ash faced Alexa's sister Viola, the Gym Leader of Santalune City who specialized in -type Pokémon. During their battle, Ash faced difficulty against Viola's Surskit, who gained an advantage over Pikachu By freezing the arena, turning it into an ice field. Ash decided that what needed improving was his Pokémon's balance, and with Alexa's help, engaged in special training designed to combat this flaw. Clemont also tried to help using one of his latest devices, but the machine backfired and exploded. In a rematch, Ash ultimately defeated Viola and claimed the Bug Badge, his first badge from a Kalos Gym. Much later, Ash battled against the Cyllage City Gym Leader Grant and his -Type Pokémon. Having seen Grant defeat Viola at the Battle Chateau, Ash sought a way to defeat Grant's Rock Tomb. When he faced Grant, this ended up becoming Rock Tomb Climb, the use of which earned Ash his second Kalos Badge, the Cliff Badge. Some time later, Ash battle Moria, a Sky Trainer who specializes Sky Battles, and her Talonflame. During the battle his Fletchling evolved into a Fletchinder and won.

At the Pokémon Summer Camp, Ash and his friends met Shauna, Trevor, and Tierno. He later had a first-touch-battle against Tierno's Squirtle with Froakie and lost. After spending a good time at the Pokémon Summer Camp, Ash went to Shalour City and battled Korrina, a Gym Leader who previously traveled with Ash and his friends in order to help her understand Mega Evolution with her Lucario. Despite a failed attempt of using Tierno's dancing strategy, Ash managed to win his third Kalos Badge, the Rumble Badge.

Season 18: XY Kalos Quest
Soon, he teamed up with a ninja named Sanpei and battled against Saizo and his Barbaracle. During the battle, his Froakie evolved into a Frogadier and won the battle using its newly-learned Aerial Ace move. Three episodes later, Ash and co. encountered a wild Goomy who had fled its home on the back of a Swanna. The Goomy was frightfully timid, even being scared of Dedenne. After taking some time to care for it, Ash and the others discovered using one of Clemont's inventions that Goomy's home had been attacked by Bug-type Pokémon, which left the poor creature traumatized, and possibly having some deeper issues. Wanting to help it, Ash invited it to travel with him. Delighted, Goomy accepted, becoming Ash's fourth capture.

Finally arriving in Coumarine City, Ash had to first deal with Team Rocket trying to kidnap the Vanillite evolutionary line. In searching for Vanillite, its evolved forms had covered the city in ice, which was stopped by the Coumarine Gym Leader Ramos. In the very next episode, Ash faced down Ramos in his Gym battle. after enduring sitting through tea and helping the old man water and weed his garden. During this time Ramos saw Ash impatiently yanking out weeds without a second thought and slowed him down, telling him that if he rushes, he will miss the important things. Ash later had to apply this lesson in the Gym battle: Figuring his Type-advantaged Fletchinder would easily win, Ash had to endure both it and Hawlucha succumbing to Ramos' Weepinbell's Poison Powder; Ash managed to defeat Weepinbell with Frogadier before facing down Ramos' Gogoat. While Frogadier was surrounded by a torrent of Gogoat's Razor Leaf, Ash remembered what the older man had told him about missing the important things. Using this lesson, Ash slowed himself down and was able to guide Frogadier more effectively; he won the battle and the Plant Badge and celebrated his fourth Kalos Gym victory.

Ash and the gang later heard about a festival where Trainers give gifts to their Pokémon. Ash agreed to go with Serena to shop for things to get for their Pokémon, but alone as he wanted the gift to be a surprise. To Serena's disappointment, Ash frequently ran off during their time together to see if a gift would be good to give his Pokémon, or later when he finally found out what to get them. Between these two moments, Ash ended up winning a blue ribbon from the monorail company. After dealing with Team Rocket yet again, Ash and his friends gave their Pokémon their gifts. For his Pokémon, Ash had done the simple thing and gotten them all a nice bounty of berries. Later, while watching the fireworks, Ash took Serena completely by surprise when he handed her a gift from himself, saying it was because of her that he was able to find a gift for his Pokémon. This marks the first and to date only time Ash has ever given a present to one of his female companions.

While traversing the Lumiose Badlands, Ash and co. happened upon a wounded Spoink. After Clemont gave it medical aid, it led the gang to an oasis where it lived that had been taken over by a rogue Grumpig that was being manipulated by Team Rocket, who used the Spoink as leverage to force Ash to hand over Pikachu. Goomy escaped and faced down Grumpig but was losing for a time. When Grumpig was about to hit Goomy with an Iron Tail, Ash intercepted the attack and took it to the chest in Goomy's stead. Moved by Ash's willingness to protect it from danger at his own expense, Goomy evolved into Sliggoo and defeated both Grumpig and Team Rocket with its newly-learned Dragon Breath attack.

Later, the gang happened upon the Lumiose Power Plant. Team Rocket had hijacked the plant and were using its microwaves to control Electric-type Pokemon, including Pikachu, Dedenne and Luxio. After the ordeal was over, Ash, Serena and Bonnie temporarily bade goodbye to Clemont, who wished to return to Lumiose City to train and become stronger so that he could give Ash a worthy Gym battle.

As time went by, Ash reunited with his rival from Pokémon Summer Camp, Tierno. They proposed a practice battle in order to help Ash get stronger for his promised battle with Clemont. But it was interrupted when Team Rocket showed up and captured their Pokémon. However, while battling Team Rocket, an explosion causes a wild fire which engulfed around Ash and the others. Sliggoo, who was determined to not let its trainer meet the same traumatizing fate, summoned a rainstorm to douse the fire, evolving into Goodra in the process. After blasting Team Rocket off with its newly-learned Dragon Pulse attack, Ash and Tierno resumed their practice battle, which resulted in Ash winning the match.

Later, after arriving in Lumiose City, and after resolving a crisis concerning the Clembot, Ash and Clemont faced each other in their promised gym battle. Despite Clemont electrifying the field with his Luxray's Electric Terrain, Ash managed to win the battle and earn his fifth badge, the Voltage Badge.

After leaving Lumiose City, Ash and his friends came across Goodra's old home in the wetlands. There, Ash learned about Goodra's home being taken over by a Blue Flower Florges and her army of Bug-type Pokémon. Goodra challenged Florges to a battle for leadership, which resulted in Goodra learning Ice Beam and winning the battle. However, the celebration was cut short when Team Rocket injured Goodra and blackmailed Florges into capturing Pikachu, Dedenne and Goodra's friend, Wooper. When Ash went off to save the Pokémon, he learned from Team Rocket that Florges blamed on the Pokémon for draining the water and was trying to save her sick child, a Blue Flower Floette. After resolving the crisis and saving the wetlands from Team Rocket, Floette was successfully cured and Goodra and Florges made a truce, bringing peace to both sides at last. Ash decided to leave Goodra in the wetlands so it could be happy with its friends and serve as their protector.

Shortly after, Ash and his friends made it to Laverre City and met Sawyer, a young trainer who knew Clemont from when the latter was training for Ash's battle. During their time together Ash and Sawyer had a Double Battle, but were interrupted by the fashion show hosted by the Laverre City Gym Leader Valerie. As the boys watched the show, they were surprised to see Bonnie and Serena in it. At the end of the show, Valerie challenged Sawyer to a battle which she easily won with her Spritzee due to its Fairy-type immunity to Bagon's Dragon-type moves.

The next day, Ash and Valerie faced each other in the Gym Battle for the Fairy Badge. Despite Valerie having a Type advantage and defeating Fletchinder with the effect of Spritzee's Trick Room, Ash came around from behind and surprised everyone by using his Hawlucha to destroy the Psychic-type move with its newly-learned Bug-type move X-Scissor before it knocked out Spritzee with High Jump Kick to give Ash the win.

While the gang was picnicking, Hawlucha stumbled upon a Pokémon Egg which hatched into a Noibat. Since Ash was the very first person Noibat saw, it imprinted on him and thought he was its parent. As the baby Noibat was a poor flyer, Ash called on Hawlucha and Fletchinder to act as its mentors. After saving both Hawlucha and Noibat from Team Rocket, Ash offered to take Noibat with him to help it learn how to fly which it eagerly accepted, becoming the new fifth member of Ash's Kalos team.

When Ash and Frogadier met Olympia in Cloudy Fate, Bright Future! after winning a brief battle with Carrie, she read his memories and along with seeing a vision of it gaining a new power, she revealed that at the Froakie breeding facility, as a Froakie, he preferred being alone to train instead of socializing with the others. When he was asked to join, he politely refused, which was then met with him getting attacked by rest of the Froakie. This made him distant towards others despite doing good, and it wasn't until Ash showed him love that made him finally connect to a trainer that understood him.

In All Eyes on the Future!, Frogadier was used to battle along aside Talonflame in a Gym Battle against Olympia and her male and female Meowstic, defeated them both and allowing Ash to win the Psychic Badge.

Season 19: XYZ
Shortly after as the group head towards Snowbelle City in From A to Z!, the group comes across a mysterious Pokémon, dubbed Squishy by Bonnie, who was being pursued relentlessly by the villainous organization, Team Flare, prompting the group to put it under their own protective custody.

Eventually, they come across Sanpei's hometown in The Legend of the Ninja Hero! and A Festival of Decisions!, in which they get involved in a conflict, during which Frogadier evolves into Greninja, and obtains a powerful new Forme.

Ash eventually met Alain, who was intrigued by Greninja's new forme. The later had a battled with Alain and his Charizard, and despite putting up a good fight, he lost.

He and Alain faced off again in a more even battle while trying to figure out the mysterious power his Greninja had been using since it evolved. However, when Greninja pushed too hard on using its form, Ash collapsed to the ground and Alain immediately called off the battle. Once Ash regained consciousness, he realizes that he and Greninja have to be more careful in using that form.

Ash honors Diantha's request for a battle after training. However, despite Greninja finally managing to reach its final form of the Ash-Greninja technique and gaining the upper hand against Diantha's Gardevoir, Ash pushed too hard on using the Ash-Greninja form, and passed out again. Once Ash regained full consciousness, he vowed to fully master Greninja's form.

Ash meet up with Sawyer again and they have another battle. At the end, Ash lost due to Greninja failing to use the Ash-Greninja form, which left Ash doubtful in mastering the form.

When Ash and his friends finally arrive in Snowbelle City, they met up with the Gym leader, Wulfric and Ash challenged him to a battle in hopes of getting his final badge. During the battle, his Pokémon suffered a huge amount of damage due to the hailstorm caused by Abomasnow's Snow Warning ability and Avalugg's Ice Body ability. After losing the battle, Wulfric explained to Ash that even though he trained Greninja very well, he doesn't have enough trust in their bond, which left Ash incredibly devastated. Upon seeing how badly hurt Greninja was and blaming himself for losing the battle, Ash decides to leave Greninja and wandered off into the Winding Woods alone, with his future in the Kalos League and as a Pokémon Trainer left in serious doubt and his confidence in tatters.

The following morning, Ash's friends learned that Ash hasn't returned. Serena decided to look for him but once she found him, he was still upset. Serena tried to cheer him up by reminding him about the advice he gave her from when they were little and throughout her journey, but Ash, who was still depressed, yells at her. His sudden outburst causes Serena to become upset and angry at him for yelling at her, which results her in throwing snowballs in his face. Before she left, she told Ash that the way he is right now is not the same person she knew. After Serena left, Ash felt remorseful for yelling at her and realized that he is not getting over his depression the right way. While trying to pull himself together, a sudden blizzard appeared and Ash had to seek shelter in a cave. He spotted several Pokémon who were also seeking shelter and offers them to come in the cave with him. This made him remember the day when he took shelter under a tree when a rainstorm hit during his field trips in his childhood days. However, he saw a group of Spewpa who were about to fall off a cliff during the storm. Ash tried to save the Spewpa, but he ended up falling with Spewpa down the ravine. Luckily, he was immediately saved by Greninja. However, when one Spewpa started to fall off the cliff, but Ash and Greninja managed to successfully synchronize their feelings and save the falling Spewpa, perfecting the Ash-Greninja form in the process. After saving the Spewpa, Ash and Greninja made amends for their past actions. Ash understands after being alone, the promise he made with Sawyer, how he wanted to get 8 badges faster, and how he really wanted to beat Wulfric, Ash realizes that he was very impatient. After the storm cleared, Ash and Greninja reunited with the others. Ash then apologized to Serena for yelling at her and thanked her for knocking some sense into him. Upon returning to the Pokémon Center, Ash learned that the Kalos League will take place in Lumiose City, which reminded him of the place where he and Greninja first met. With his full confidence back, Ash and Greninja promised to start over again and went off to train for his rematch against Wulfric.

Ash faced Wulfric in a rematch with Pikachu, Talonflame and Greninja, and this time emerge victorious, earning him his eighth and final Kalos gym badge.
