Hannyabal

ハンニャバル

Hannyabal serves as the vice-warden in charge of Impel Down. He frequently describes himself as 'ambitious'.
He is also intensely eager to succeed the current chief warden, Magellan, which causes him to frequently slip up in conversation. He often states that he wants to be the warden and replace Magellan, even when discussing topics completely unrelated to the matter.
He is willing to permit criminals to escape so that he can blame Magellan and take his position as Chief Warden.
