Ash Ketchum is the main character of Pokémon. His name in Japanese is Satoshi; in French, Sacha and in Korean, Jiu. He was based on the Pokémon Red and Blue main character, and was named after the creator of Pokémon, Satoshi Tajiri.
He starts his Pokémon journey at the age of ten. At first, he was clueless about Pokémon training, but he's changed a lot during the series becoming a really skilled trainer. He's very excitable, courageous, empathic and sometimes a bit too inocent. He's also extremely confident and valiant, but he is also arrogant and very stubborn.
Ash lives with his mother, Delia Ketchum. His father is never introduced. The anime suggests that his father was once a Pokémon trainer, but it is unclear whether he is still living.
When it comes to love, Ash is still indifferent to romance or members of the opposite sex. He hasn't shown any overt proof of liking Misty. However, we Pokeshippers assume/hope he will end up realizing his true love is no other than her, since there have been some hints that evidence what he feels about her.
