Episode 914

"Finally Clashing - The Ferocious Luffy vs. Kaidou" is the 914th episode of the One Piece anime

Short Summary
Right after the destruction of Oden Castle, Luffy enters a furious battle with Kaidou.

Long Summary
Kaidou's Bolo Breath destroys Oden's castle, leaving the witnesses in shock, including Luffy, Hawkins and Jack. In anger, Luffy chases after Kaidou, who unleashes a drunken rampage on Okobore Town. He jumps into the sky and uses his Elephant Gun move to strike Kaidou in the head, causing him to fall to the ground.

Kin'emon and Kiku, having survived Kaidou's attack, get up. To Kin'emon's shock, however, he finds a smoldering gap where Oden's castle was. He goes to the town in case Kaidou wakes up and rampages again, while Kiku goes to the mountain to find Momonosuke and the other Straw Hats. Luffy also heads in the same direction, only to find Speed's injured body.

Speed explains that she was taking Tama back home, but was encountered by Kaidou. They were attacked by Kaidou's fire breath. Luffy laments Tama's death. Out of anger, he shouts out Kaidou's name, making the dragon wake up.

They almost immediately engage in fierce battle. Kaidou manages to knock Luffy into the ground using his tail, but Luffy gets up. In Tama's memory, he uses the Elephant Gatling Gun on Kaidou, pummeling him with giant Haki-infused fists.
