Episode 334

"The Super Final Atsu Atsu Battle! Luffy VS the Scorching Don" is the 334th episode of the One Piece anime.

Short Summary
Atsu Atsu no Mi gives the Don all sorts of powers, from throwing blasts of heat, heating his skin to extreme temperatures, to even being able to fly by blowing steam out his nose. Luffy has difficulty fighting him due to being unable to hit him directly without being burned. Meanwhile, Puzzle defeats Campacino, the rest of the Straw Hats search for their flag, and Robin and Lil reconcile with one another. Outside, the fight heats up when Luffy activates Gear Second, and sends the Don flying through the wall of his mansion with Gomu Gomu no Jet Pistol, sending the Don's flags to the winds. The Phoenix Pirates recover their flag, but Chopper realizes that he has accidentally grabbed the wrong flag. The Don recovers from the hit and resumes his fight with Luffy.
