Hannyabal

Hannyabal was the Vice Warden of Impel Down before Blackout attacked the prison.

Description
Hannyabal was described as being a "devil-man with a face shaped like a Japanese hannya mask".

History
Hannyabal worked as the Vice Warden of Impel Down alongside Chief Warden Magellan and Chief Guard Sadi.

In 100,080 CMT, Hannyabal and the rest of the Gaolers managed to escape Makuta Blackout's attack on Impel Down through the assistance of an unidentified individual, who warned them of the attack beforehand and gave them instructions on how to escape. Level Six contained a clue as to how the Gaolers escaped: there were no significant residues left that matched the prisoners thought to have been killed in the battle, even though an explosion occurred in such close proximity to them that they should have been fossilized. Zev Raregroove was aware of Hannyabal's survival and once mentioned it in passing.
