One Piece: Season 1, Episode 484

1 - 484: The Navy Headquarters Falls! Whitebeard's Unspeakable Wrath!

Luffy's mind collapsed due the emotional trauma when Ace died, so Jinbe takes him away. The Whitebeard Pirates and their Allies then vow to protect him. An enraged Whitebeard fights Akainu, having his torso pierced through once again, but still defeats the Logia user whilst 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 Impel Down's Level 6 prisoners, as Blackbeard exclaims he's happy to have arrived on time to see Whitebeard's death.
