Episode 473

"The Encirclement Walls Activated! The Whitebeard Pirates Driven Into a Corner!" is the 473rd episode of One Piece.

Summary
Whitebeard enters the battlefield, which raises the morale of his pirates and prompts them to clear the way for him. The Marines shoot cannonballs to him, but he uses his powers to deflect them and destroy the cannons. The Marines try to activate the encircling walls, but the ice prevents them from raising completely. A confused Squardo is soon to blame himself for being fooled, as the Decalvan Brothers and the rest of the commanders, are infuriated by the foul tactic used, while Marco asks Squardo if "he can redeem himself by crying". Luffy makes his way through and is followed by Jinbe and Emporio Ivankov, who is soon to notice the retreat of the Marines, from which Jinbe is also cautious, but agree that there is no way back since Whitebeard is on the battlefield.

Sengoku is infuriated at the delay of the walls, which forces Vice Admiral John Giant to try buy some time, and quickly breaks through multiple pirates and attacks Whitebeard, who easily blocks his attack, and unleashes a massive earthquake, that drastically alters the balance of the sea and Marineford much to Donquixote Doflamingo's amusement. As Luffy is about to fall into an abyss, Jinbe pulls him out. Coby and Helmeppo are soon to notice that much of the plaza is destroyed. John Giant is impressed, but decides to fight in the name of Absolute Justice, and is easily defeated by one of Whitebeard blows, that breaks through the ice, and the bay, and is about to reach the scaffold but the three Admirals block the shock wave with Haki and are soon to blame each other for the delay on the walls.

Commander Jozu orders his mates to attack and use the chance provided by Whitebeard, that has set the Marines out of balance. Sengoku orders that all power is given to the walls. Luffy tries to reach Ace but the large walls activate trapping all the pirates, and while they to break it, it is futile. However they find that there is still a path opened by Oars Jr.'s body, as his blood makes the system less effective. Everybody is impressed at how he is "still fighting". But then Sengoku's patience ends and orders Akainu to attack, which makes him launch lava at the sky. This in turn silences the battlefield for a moment, but the silence is broken by lava raining down from the sky. Akainu's attack is meant to melt the ice, leaving no way for the pirates to advance. Luffy is shocked at this event.
