Episode 416

"Rescue Ace! The New Destination is the Great Prison" is the 416th episode of the One Piece anime.

Short Summary
Following a party, Luffy learns from Nyon that Hancock is a Warlord of the Sea, and that they have been called together as the Marines is launching an all-out offensive on Whitebeard. When Luffy hears that they are planning on executing his brother Ace at Marinford to lure Whitebeard out, he decides to save him from the prison Impel Down before he's transported away. The only hope of him getting there in time is for Hancock to answer to the call for the Warlords, so Luffy can hitch a ride on her ship, but the empress has just caught a disease, and is lying in bed.

Long Summary
After telling Luffy all about her past, Hancock agrees to give him a ride to Sabaody Archipelago with her Yuda-towed ship. She also invites Luffy to their banquet tonight and to rest inside. At the banquet, Luffy eats everything around him, and the girls seem suspicious. The Kuja Pirates misunderstand their Snake Princess's actions and prepare to attack Luffy. But before they can, Luffy, bored, starts to sing Bink's sake and dances with a pan and spoon. It makes everyone laugh, and the party begins. But the girls, who have never seen a man before, interrogate Luffy and touch him. He escapes with Marguerite to Elder Nyon's house. There Luffy finds out that Hancock is a Shichibukai, the war between the Whitebeard Pirates and the Marines and, most important, his brother Ace is about to be taken to his execution. He says sorry to his comrades after deciding to rescue Ace at Impel Down, and asks Elder Nyon how he can rescue Ace. Elder Nyon tells him that there's only one way to make it to his brother in time, by asking Hancock to accept the call of the Marines. But Hancock has caught an unknown disease.
