Chase was born in Slateport (Hoenn), but moved to Castelia (Unova) a few years back. Chase realized his love for Pokemon early on in life, and often brought back random Pokemon to his house without the use of Pokeballs, to the dismay of his parents. As he grew older, he learned more about the bond between human and Pokemon. Chase has a deep understanding of pokemon, and as such, wants to become a ranger to help deescalate difficult encounters between human and wild Pokemon.
His Pokemon are pretty low level because he’s a little lenient with them. His father a little disappointed in him, because he wanted Chase to follow in his footsteps in becoming a battle expert. Chase doesn’t like having to hurt his Pokemon, and prefers not to battle.
