Impel Down (インペルダウン Inperudaun?) is one of three main locations of the World Government[ch. 549] and the world's greatest prison.[ch. ?] Chief Warden of Impel Down is Magellan (マゼラン Mazeran?), a man with the ability of the Paramecia-type Venom-Venom Fruit (ドクドクの実 Doku Doku no Mi?), which allows him to generate and manipulate poison as well as making him immune to any type of poison.[ch. ?] His ability does not, however, spare him from diarrhea caused by poisoned food.[ch. ?] As a result, he spends approximately ten hours each day in the bathroom relieving himself.[ch. ?] Second in charge of Impel Down is the exceedingly ambitious Vice Chief Warden Hannyabal (ハンニャバル Hannyabaru?).[ch. 526] He often shows off how tough he is to the prisoners, which is the reason he is admired amongst the guards.[ch. 536] However, he cares more about his own position than the security of the prison.[ch. 535] His weapon of choice is a double bladed naginata.[ch. 543] Below Hannyabal stand the Chief Guards Sadie (サディ Sadi?) and Saldeath (サルデス Sarudesu?). Sadie is a very sadistic woman who uses a thin, torturing whip in battle.[ch. ?] Saldeath wields a trident, which also functions as a flute to direct his subordinates, the Blugori,[ch. 543] blue, legless creatures resembling gorillas.
