Short Summary
Whitebeard aims to take down the whole of Marineford and orders his crew and the other pirates to flee. Ace gives his final, grateful farewell to his captain before trying to escape as well. However, Akainu tauntingly mocks Whitebeard, and Ace, feeling angry and insulted on Whitebeard's behalf tries, to take him on. But it is quickly apparent that Ace is outmatched, and when Akainu aims to land a fatal blow on the now exhausted Luffy, Ace takes the hit for his younger brother instead.

Anime and Manga Differences

 * In the manga, this is when the Visual Den Den Mushi wakes up, but it woke up earlier in the anime. Also in the anime, the Visual Den Den Mushi gets terrified of the Impel Down escapees and hides in its shell and the escapees had to convince the Den Den Mushi to come out.
 * Buggy seems less eager to take Whitebeard's head than he does in the manga.
 * In this episode, Akainu is seen removing his cap.
 * In this episode, Ace's beaded necklace breaks apart and the beads fall to the ground when Akainu struck him, while in the manga it remains intact. This was most likely done to add suspense.
