Olive

Olive is a fierce pirate who was captured and sent to Impel Down. She seduced Hannyabal and attempted to escape, but was thwarted by Magellan and locked away. She appeared exclusively in the anime, briefly in Hannyabal's flashback. She had a bounty of Beli50,000,000, meaning she was presumably sentenced to Level 3. (Source: One Piece Wikia)
