Episode 520

"A Great Buildup - The Fake Straw Hat Crew's Intimidation" is the 520th episode of the One Piece anime.

Long Summary
The episode opens with Brook finishing his concert and thanking his fans. Later, he goes backstage and is given a bottle of water and pours the water on himself. Later on, his fans call for an encore which he accepts. Then the Marines come and want to arrest him because he is a member of the Straw Hats. Brook starts to sing his last song, proclaiming that Luffy is still alive. The Marines open fire, but Brook already escaped on a flying fish. The episode also shows when Chopper, Usopp, Robin, and Nami reunite at the Thousand Sunny. Chopper and Usopp find Franky and seem to be amazed over his new equipment of his body. We also notice that Franky's voice can become seemingly robotic and he can do several changes to his body parts. His hands have become fairly larger, but we see that a new arm is revealed.

Anime Notes

 * The "New World" song is longer than in the manga, where Brook only starts to sing it.
