Episode 484

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

Short Summary
Luffy's mind collapses as Ace dies in his arms. Jinbe takes him away, while the Whitebeard Pirates and their Allies vow to protect him. Whitebeard fights Akainu, having his torso pierced trough, but still defeats Akainu, and destroys Marineford as well, splitting the ground between him and his sons. Surprisingly, the Blackbeard Pirates appear in Marineford, with their new members, as Blackbeard claims he's happy for arriving in time to see Whitebeard die.

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 trough Whitebeard's torso using the same attack (Mei Go).
 * In the manga, Akainu was sliced in the neck by the combined efforts of Vista and Marco. In the Anime not only did this not happen, but Marco just blocked Akainu's way and Vista did not even fought him.
