Carl is the leader of a Super Pokémon Battle troupe. He and the troupe provide entertainment far beyond that of Pokémon battles as its the ultimate show, born out of an unprecedented fusion of Pokémon battles and drama. He orchestrates battles within a set story.
He was the cornerman for his Luchablu who used to be the Champion of a tournament in the Kalos region where Fighting Pokémon compete against each other.
Carl accidentally caused it to hurt its knee at a tournament and it can't be involved in serious battles any more.
Carl decided to come up with Super Pokémon Battles as a way for Dark Lucha to put on great shows and shine in them like never before.
