Dimple wants to be a god. Specifically, he wants to be worshipped by all humanity. Despite having that kind of ego, he didn't hesitate to put himself at Mob's mercy in the hopes of using the boy to his advantage. At first, he wanted to steal Mob's body and use it to become a god, but he eventually decided to try to make Mob a god instead.
He is the leader of the psychic organization known as Claw. Once set on a path for world domination by recruiting espers, he was eventually shown a better path by Shigeo Kageyama to reflect upon his life goal and his family, including his son Sho Suzuki after being taken away.
