Vincent

 Vincent was abandoned in the wild by his birth parents and found and taken in by a pack of zoruas and zoruarks, due to this vincent can speak to and understand pokemon, at the cost of a lot of common human sense....

he was hit in the back by a firework and has ptsd from it as well as a scar

after becoming a trainer Vincent had a accident that caused him to loose one of his eyes and for his other to be nearly completely blind and theres a huge scar across his face

he names most of his pokemon using japanese or names them after food
