Ghetsis is a manipulative man who wants to convince people to liberate Pokémon from human slavery. However, this is only so he could rule the region unopposed. He is mentally abusive as well, constantly calling N a freak. It is implied that Ghetsis is willing to kill children, as shown when he seeks to eliminate the player to forever keep his real goal a secret and attempts to freeze the sequel's player by using Kyurem to avenge himself for his loss years prior.
He's dating Colress.
