Episode 621

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

Short Summary
Franky in his Shogun 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 refuse 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 has allied with the enemy and that the odds are against them, Buffalo and Baby 5 decide to hightail out of Punk Hazard, with Caesar Clown in their possession. Before Law could stop them, Luffy stops him, saying that Usopp and Nami will handle this. The two Straw Hats prove Luffy right, as they easily stop the fleeing pirates and succeed 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.

Long Summary
Buffalo is surprised by how strong the Franky Shogun is. He then charges at Franky, saying that no one has ever been able to dodge the next attack. Using his powers, he spins Baby 5 on one of his chains, who in turn uses Sickle Girl, and then slams her into Franky Shogun's left arm, impaling it. Franky laughs and says he will give them credit, but only for breaking through the robot's armor, and compares the pair to a praying mantis taking on a warship. He then grabs Baby 5 and yanks on the chain, causing Buffalo to lose his balance and hurl forward. He then declares that the Gaon Cannon has set foot on land, and shoots them with Franky Shogun's most powerful attack, General Cannon. As Buffalo and Baby 5 are reeling from the attack, they wonder why someone like this would try to impede them taking Caesar. Franky then looks down from the tanker and sees Caesar lying there, and wonders how the scientist got there. Buffalo stands up, declaring that he is not going down that easily, saying that such a defeat would drag Joker's name through the mud. Baby 5 then declares that they will be taking Caesar with them, no matter what it takes. Franky then asks them if he is correct in concluding that they want Caesar.

Back in R-66, the exit is in sight. Usopp begs Nami to conjure up some wind, so they will not die. Everyone cheers as they exit. Franky is happy to see that everyone made it out. Baby 5 and Buffalo are seen surprised by their sudden arrival. Luffy, Usopp, Chopper, and the rest of the boys in the cart are very excited to see the robot, while Nami, Robin, Tashigi, and the rest of the girls are visibly unimpressed. Law is surprised to see Buffalo and Baby 5, who asks him if he is really going to defy Joker, who has been saving the heart seat for him. Luffy asks if those two are Law's friends, and Law tells him no. Realizing their sudden disadvantage, Buffalo and Baby 5 grab Caesar and start to fly away. Usopp tells everyone to leave the escaping pair to him. Law is about to use his powers and tries to argue, but Luffy cuts him off, telling him that Usopp has things under control, and Zoro tells him not to underestimate Usopp. Law argues, saying that if they get away, the plan will be ruined. Nami cuts him off again, saying that if they are going to have an alliance, then Law needs to trust them more, adding that she needs to do a little fighting after doing nothing but running. Usopp and Nami then declare that they will take care of the far away enemies with their backs turned, and Zoro tells them to hurry up. Usopp then orders his Bakun Grass to grow into his Kuro Kabuto, which then starts eating the nearby rubble and twisted metal. Buffalo tells Baby 5 to watch the rear, since he cannot while flying. While Baby 5 vows to defend them with her life, a giant weather egg, called Lightning-chan by Nami, flies over them and releases a huge storm cloud. Baby 5 looks at the cloud worriedly while Nami declares they will not get away. She then attacks them with Thunder Breed Tempo, landing a direct hit.

As they start falling, Buffalo calls to Baby 5 and realizes she is unconscious. Usopp then attacks them with Killer Shooting Star Rush, shooting several pieces of stone from the rubble at them. Caesar tells Buffalo that, since he cannot move, he must protect him and Buffalo declares that he will complete a mission for the Donquixote family as they are pelted with rubble. As the two go down, Caesar manages to stay airborne as the shots pass through him. He then decides he  will go to Dressrosa by himself. Usopp tells him that escaping is useless, since the last shot was seastone handcuffs. The cuffs catch Caesar around the neck. Everyone cheers as Usopp proudly declares that he will fight anyone whose back is turned. As the three fall into the ocean, Law declares the first step  of his plan is complete and Luffy asks Law what he thought about his crew's abilities.

Somewhere on the sea, a shadowy figure has overslept, and is wondering how to get to Punk Hazard.
