Episode 484

"Marine Headquarters Collapses! Whitebeard's Silent Rage!" is the 484th episode One Piece.

Short Summary
Luffy's mind collapsed when Ace died so Jinbe takes him away, while the Whitebeard Pirates and their Allies vow to protect him. Whitebeard fights Akainu, having his torso pierced through once again, but still defeats the logia user, while starting the destruction of Marineford; splitting the ground between him and his sons. Surprisingly, the Blackbeard Pirates appear in Marineford, with their new crew members. Everyone stares in shock at the supposed Level 6 prisoners, as Blackbeard exclaims he's happy to have arrived on time to see Whitebeard's death.

Anime and Manga Differences

 * In the manga, Akainu melts off half of Whitebeard's face. In the anime, only part of his facial hair is melted off. Instead, Akainu pierces through Whitebeard's torso using the same attack (Meigo).
 * Akainu was able to push Marco out of the way to go after Luffy, where as in the Manga he was still still trying to get past him when Whitebeard attacked.
 * The fight between Whitebeard and Akainu is extended.
 * In the manga, Luffy's mind instantly collapses when Ace dies, while in the anime, there is a montage of Luffy having flashes of Ace dying while crying before his mind collapses.
