>>56248090Very low self-confidence due to an overprotective, yet judgemental sister and probably just general shyness. Having a competitive older sibling caused him to always feel weak, and he blamed his problems (being shy, feeling overlooked, lack of friends etc) on his lack of power.
He admired Ogerpon because he thought it was strong, as it killed 3 Pokémon all by itself. And he thought it didn't care that everyone shunned it. He said himself: he wants to be as cool as the ogre. Being "denied" by Ogerpon convinced him of his misconception, he thought the MC was preferred because of their power (when it truth it was probably cause they weren't from Kitakami).
That's why he became obsessed with power. He thought it would solve all his problems.
