Ash Ketchum

Ash Ketchum (Japanese: サトシ Satoshi) is the main character of the Pokémon anime. He is also the main character of various manga based on the anime, including The Electric Tale of Pikachu, Ash & Pikachu, and Pocket Monsters Diamond & Pearl.

He is a Pokémon Trainer from Pallet Town whose goal is to become a Pokémon Master. His starter Pokémon was a Pikachu that he received from Professor Oak after arriving late at his laboratory. In Pokémon the Series: Sun & Moon, he becomes the first Champion of the Alola region's Pokémon League.

He shares his Japanese name with the creator of the Pokémon franchise, Satoshi Tajiri. His English surname is a pun of the English motto, "Gotta catch 'em all!."

In Seeing the Forest for the Trees!, Ash remembered getting lost in a forest while looking for Pokémon. He brought some wild Pokémon out of the rain and found them some shelter in a tree trunk. Ash's happiness about that moment made him think about how much he wanted to become a Pokémon Trainer.

At the age of six, Ash learned that Professor Oak would be holding a Pokémon Summer Camp, and eagerly asked his mother Delia if he could attend. Seeing her son's enthusiasm, she signed him up but also told him that she had things to do outside of home during the day the camp would take place, so he would have to get himself there in time on his own. Unfortunately for Ash, he ended up breaking his alarm clock in his sleep and overslept, missing the camp.

Later, Ash managed to attend another one of Professor Oak's Pokémon Summer Camps. One day, another camper named Serena got lost in the forest and wounded her leg after getting startled by a Poliwag. Ash, who was looking for the Poliwag, came to her rescue and wrapped a handkerchief around the wounded knee to brace it. He then helped her up and guided her out of the forest.

In The Ties That Bind, Ash recalled a day when he was about to start his Pokémon journey. He and Gary Oak both fished out an old, rusty Poké Ball, which snagged on both their lines. After arguing about who would keep it, they broke it in two, each keeping one half as a reminder of that day.

Sometime after his return to Kanto, Ash joined Professor Oak in attending the opening of the new Cerise Laboratory in Vermilion City. During the opening ceremony, the head of the institute, Professor Cerise, informed the attendees that a rare Pokémon would be appearing at the local port shortly. Ash eagerly rushed over there and found out the rare Pokémon was a Lugia. During this encounter, he also met a boy named Goh, and the two shared a ride with Lugia throughout Kanto. When they later returned to the Cerise Laboratory, Professor Cerise was amazed by the information they had gathered about Lugia, and he asked them to become his research assistants. They accepted the offer and were provided with their own room to stay in. Delia also left Mimey at the institute to take care of Ash while he stayed there.

Later, Ash and Goh traveled to the Galar region to watch the finals of the World Coronation Series. The match ended in the victory of Galar's undefeated Champion Leon, thus making him the Monarch, the official strongest Trainer in the world. Inspired by this, Ash decided he wanted to battle Leon himself. However, before he could challenge him, a Gigantamax Drednaw went on a rampage and started causing havoc. While Ash and Goh battled it, Pikachu ended up Gigantamaxing as well, therefore giving him enough power to defeat Drednaw. Leon, impressed by Ash's performance, accepted his challenge to a battle. After Ash lost, he decided to take part in the World Coronation Series as well and climb through its ranks to one day challenge Leon again.

Upon entering the World Coronation Series, Ash immediately started building up a winning streak, soon even reaching the Great Class after defeating Korrina. Ash's winning streak came to an end, however, when he encountered Bea, a Fighting-type Gym Leader from Galar, who was also aiming to defeat Leon. In their two-on-two match at the Fighting Dojo, Ash failed to defeat a single one of Bea's Pokémon, with her powerful Grapploct with its many limbs and Octolock proving especially troublesome. This crushing defeat caused Ash to start losing his self-confidence and led to him entering a losing streak, even resulting in him falling back into the Normal Class. This caused him to get depressed, until he was snapped back into his senses by a motivational speech from Goh. Thanks to this, he quickly fought his way back into the Great Class and challenged Bea to a rematch at the Cianwood Gym, managing to tie with her this time.

One night, Ash's Dynamax Band began to glow. After learning about cases of Pokémon Dynamaxing in Galar outside of Power Spots, Ash and Goh headed to investigate. Soon after arriving in the region, Ash and Goh ended up getting separated while in the Slumbering Weald, where Ash encountered Zacian, whereas Goh encountered Zamazenta. Later, Ash encountered Leon and joined him in taking care of the Dynamax Pokémon rampaging around Galar. During this quest, they ended up encountering Chairman Rose and Oleana, and Ash accompanied them to dine and spend a night at Rose Tower. When he departed the next day to rendezvous with Goh, Eternatus emerged from the Hammerlocke Energy Plant, starting the Darkest Day and prompting Ash to head there. At the Hammerlocke Stadium, Ash re-encountered Rose and engaged him in a battle, eventually winning thanks to his newly evolved Lucario. Reuniting with Goh, the two then engaged in a battle against Eternatus, after Leon had failed to stop it. With Zacian and Zamazenta's help, they successfully defeated Eternatus and sealed it away, ending the Darkest Day.
