Episode 621

"Capture Caesar - General Cannon Blasts" is the 621st episode of the One Piece anime.

Short Summary
Franky and his mech puts up a good fight against the two subordinates of Doflamingo and he sends them flying away with a portable version of the Thousand Sunny's Gaon Cannon, but the two refused to stay defeated despite their injuries.

The fight however was interrupted with the arrival of the mine cart filled with all of the lab escapees. Seeing that Law is allied with the enemy and that the odds are against them, the two decided to hightail out of Punk Hazard along with Caesar Clown in their possession. Before Law could stop them, Luffy told Law that Usopp and Nami will handle this. The two Straw Hats proved Luffy right as they easily stopped the fleeing pirates and suceeded in capturing Caesar.

Meanwhile, far away from Punk Hazard, Doflamingo is still flying toward Punk Hazard imagining what torture he would inflict on the brats, while elsewhere on a giant penguin, a mysterious man is wondering which direction leads to Punk Hazard.
