Episode 1001

"A Risky Invitation! A Plot to Eliminate Queen" is the 1001st episode of the One Piece anime.

Short Summary
The Straw Hats battle the Number Goki. Drake is caught as a traitor by Queen and Who's-Who and he defects to Luffy's side.

Long Summary
X Drake and Basil Hawkins watch the battle from above. Secretly fearing Kaidou and Big Mom's alliance, Drake is happy that Luffy has come to stop them. He prepares to betray the Beasts Pirates, but Hawkins refuses to join him.

King and Queen also meet on the balcony, with Queen still questioning how the Udon prisoners escaped. King tells the Tobiroppo to stop all enemy invaders from climbing onto the Skull Dome to battle Kaidou.

After hearing that Drake was attempting to betray the Beasts Pirates, Who's-Who decides to carry out his own plot against the traitor. He claims that he is plotting to kill Queen, so Drake joins him to confront Queen together. However, Who's-Who instead turns on Drake, shooting him in the arm. Queen reveals that they were aware of Drake's betrayal all along; he was spotted letting Law out of prison, so they deduced that he was a traitor. Queen prepares to torture Drake for information regarding his true allegiances.

The Straw Hats aid the samurai in battling another one of the Numbers, Goki. Luffy remembers when they defeated Oars in Thriller Bark. Although that battle required the efforts of the entire crew, Luffy transforms into his Boundman form to battle Goki on his own.

Drake escapes, throwing a grenade at Queen before transforming and fleeing. Leaping into the party, he uses his swords to cut down another Number, Juki, just as Luffy defeats Goki. Drake officially defects from the Beasts Pirates, joining Luffy's side.
