"Looking for the Answer - Fire Fist Ace Dies on the Battlefield" is the 483rd episode of One Piece.

Short Summary
Ace is punched by Admiral Akainu, and falls into Luffy's arms. He then thinks about his past, and remembers his goal in life: To find out whether or not he had deserved to be born. Akainu proceeds to attack Luffy, but Jinbei stops his advance. Marco and Vista then rush to the aid of Luffy and strike Akainu with Haki imbuned attacks, but realize they are ineffective against the Admiral. As everyone else stares in shock at Ace's wounds, they deduce that his organs were burned beyond help, and tell Luffy that Ace will not make it. Just as Ace dies, he thanks Luffy for everything, while Luffy cries for his brother.
