Impel Down

Impel Down is the World Government's maximum-security prison for the most dangerous criminals and pirates. It is located underwater, somewhere beyond the Gate of Justice.

The known way, so far, to get to Impel Down is through the Gates of Justice at Enies Lobby.

Current known prisoners in Impel Down include Crocodile, Mr. 1, Bon Clay, Mr. 3, and Ace. Crocodile and Mr. 1 were imprisoned in a Marine base, but were transferred to Impel Down after most of the captured Baroque Works members escaped (Crocodile and Mr. 1 chose to stay behind). Bon Clay and Mr. 3 were captured by Hina, and presumably transferred to Impel Down for reasons similar to Crocodile and Mr. 1's transfers. It was recently revealed that Portgas D. Ace was beaten by Blackbeard and sent to Impel Down in a conversation between Absalom and Dr. Hogback after the defeat of Gecko Moria. The arrest of Ace led to Blackbeard becoming a Shichibukai. While imprisoned, Ace's life is currently in danger for an unknown reason.

The name derives from The English verb 'impel', meaning to force.
