Episode 523

"The Shocking Truth - The Man Who Protected the Sunny" is the 523rd episode of One Piece.

Summary
The episode opens when the Caribou Pirates find the fake Straw Hats. Caribou attacks Drip (fake Sanji) and fake Sogeking subsequently tries to save him, but to no avail as Caribou has Logia-type Devil Fruit powers. Coribou, Caribou's brother, is digging graves with the rest of the Caribou Pirates. In another scene, Rayleigh remembers when he first met Gol D. Roger, a thought which causes him to shed tears. Meanwhile, Sentomaru is seen reporting through a Den Den Mushi that the Straw hats are back stronger than two years before. Next, the Straw Hat Pirates are seen sailing under the sea, where Franky tells them that upon his arrival he saw Bartholomew Kuma protecting the Thousand Sunny and that the Shichibukai had been doing so for the past two years.

Meanwhile the Caribou Pirates' plan to kill the real Straw Hat Pirates is revealed as they are traveling through the water as well. Usopp spots their ship just as the Caribou Pirates' attack on the Thousand Sunny is launched.
