Bloat, the boy governor of the Rox, had dreams as big as his monstrous Joker body. He wanted to make Ellis Island a safe haven for his people, a Joker homeland. To survive, Bloat needed the Jumpers, adolescent outcasts who could steal a man's body in the blink of an eye. He needed their money to feed the Rox. Even more, he needed their terrifying powers to stave off the vengeance of a frightened world.
But the Jumpers grew even more vicious and uncontrollable every day, under the leadership of Dr. Tachyon's psychopathic grandson.
