Episode 685

"Steady Progress! Luffy's Army vs. Pica!!" is the 685th episode of the One Piece anime.

Short Summary
After Pica's arm was destroyed by Chinjao and Elizabello II, the Colosseum fighters proceed to decimate the Doflamingo soldiers. But Pica was not out of the fight and attacked again with his remaining arm, throwing the fighters in disarray. The fighters then noticed that Luffy is missing and one of them sees Luffy riding Ucy while climbing the colossus arm toward the giant head. Pica noticed this and grew his arm back, before going to strike his attacker, but Luffy was ready and breaks the giant's head off with a Grizzly Magnum. Meanwhile, Robin's group reaches the top of the plaza and manage to elude their pursuers. Pica was then revealed to be controlling the colossus from within, and prepares to cut Luffy down with a huge sword, but Zoro intercepts it and stays behind to duel Pica while Luffy races toward Doflamingo's palace.
