The Beginning of the War! Ace and Whitebeard's Past!

Whitebeard reveals his Devil Fruit powers in front of the Marines. Whitebeard and Ace's past are shown: Ace was the captain of the Spade Pirates. Ace confronts Jimbei to meet Whitebeard since Ace turned down an offer to become a Warlord. Soon after Whitebeard offered Ace to join his crew when his battle has ended, Ace attempted to kill Whitebeard to no avail. Whitebeard allowed Ace to become a division commander. However, when Blackbeard turned against the crew and killed Thatch, Ace left Whitebeard on a mission to capture Blackbeard. When Ace tells Whitebeard on the execution platform that he ignored his advice, Whitebeard says that he was the one who sent Ace to confront Blackbeard when he originally told him not to go, to cover Ace's mistake in his rescue attempt.
