Ash Ketchum is a Pokemon trainer from Pallet Town in the Kanto Region. His first Pokemon was a feisty Pikachu. He's competed in the Kanto Indigo League, the Johto Silver Confrence, the Hoenn League, the Lily of the Valley Confrence in Sinnoh, The Unova League, and has conquered the Kanto Battle Frontier.

History
Ash is the only son of Delia Ketchum. One summer Ash enrolled  in Professor Oak's 's Pokémon Summer Camp when he was young. One day, another camper named Serena g ot 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 wounded knee to brace it. He then helped her up and guided her out of the forest.

On his tenth birthday he qualified to become a Pokemon Trainer, the first step to becoming a Pokemon Master. However Ash ended up staying up until midnight the day before getting his first Pokemon, and because of this, along with the fact he accidently broke his alarm clock in his sleep overslept. He rushed to Professor Oak's lab to get his first Pokemon, but by the time he got their all the usual starter Pokemon were gone. The only Pokemon that was left was an unusualy powerful Pikachu. Ash was originally ecstatic, as he got a unique starter, but Pikachu didn't like his new trainer, zapping him as soon as Ash picked him up. Ash eventually gained Pikachu's trust when he learned Pikachu hated being confined in a Pokeball, along with risking his own life to protect Pikachu from a flock of angry Spearow. Ash only survied because Pikachu unleashed a powerful Discharge, Zapping all of the Spearow at once (along with accidentally frying a borrowed bike). After this Ash and Pikachu became inseperatable, to the point of Ash letting Pikachu ride on his shoulder instead of in a Pokeball. Ash and Pikachu have since journeyed across numerous regions, competeing in numerous tournaments, making tons of friends, and catching a lot of Pokemon.

In the  XY series, Ash traveled to the  Kalos  region with  Alexa , whom he met while traveling in the  Decolore Islands. He first visited  Lumiose City  in  Kalos, Where Dreams and Adventures Begin!, where he parted ways with Alexa and tried to challenge the  Lumiose Gym  at Prism Tower, only to be forcibly ejected from the tower when the computerized security system  found out that he didn't have any badges. He was rescued by  Clemont  and  Bonnie, who started to travel with him after he calmed down a rampaging  Garchomp  at the top of Prism Tower

Personality
Ash has shown numerous times to be a bit rash. He's a

true friend, keeping his Pikachu on his shoulder instead of a Pokeball, because of it's own preferance.
