Episode 726

"Gear Fourth! The Phenomenal Boundman!" is the 726th episode of the One Piece anime.

Short Summary
As the Birdcage closes in on Dressrosa, Luffy activates Gear Fourth, which causes his torso to balloon and forces him to constantly bounce. Doflamingo laughs at this new form, but Luffy retracts his fist into his arm and punches him, blowing him into the city far below. Luffy lands more large blows on Doflamingo as the Shichibukai struggles to keep on even footing. However, Luffy is able to change the direction of his punches and absorb Doflamingo's attacks.
