, ハンニャバル

Hannyabal serves as Impel Down's vice-warden, and has expressed his ambition in various conversations. His eagerness to become chief warden is evident, causing him to frequently slip up when speaking about it. In unrelated discussions, he often mentions his desire to replace Magellan directly. Despite this, Hannyabal is willing to let criminals escape if it means shifting the blame onto Magellan and securing his position as the new chief warden.
