Shanks Intentionally Did Not Save Ace from the Marines

In the Marineford arc of One Piece, Ace faced execution because he was the son of the former Pirate King. Whitebeard and his crew tried to rescue Ace, and Luffy joined in too. Sadly, Ace was killed by Admiral Akainu. Whitebeard also died in the battle. Later, Shanks arrived, putting a stop to the conflict.

Some theories suggest that Shanks might have been in a fight with Kaido during Ace’s execution, as Kaido was also headed to Marineford. However, it’s unlikely Shanks and Kaido fought because Shanks is so powerful that Kaido would likely have been injured.

There’s an alternative theory that suggests Shanks deliberately stayed away from Marineford. The idea is that Shanks wanted Whitebeard, a potential rival for the title of Pirate King, to be defeated. This theory implies that Shanks had strategic reasons for not intervening in the battle.

In essence, the Marineford arc involved attempts to save Ace, battles among powerful figures, and the eventual intervention of Shanks to halt the conflict. The theories add intrigue by suggesting hidden motives behind Shanks’ actions during this crucial event.

Why Did Kaido Want to go to Marineford?

Kaido probably knew Ace was Roger’s son and a “D,” and he likely understood Ace’s intention to challenge him in Wano. Kaido, claiming Luffy couldn’t be Joy Boy, might have meant Ace instead. Despite Kaido knowing a lot about Joy Boy and waiting in Wano for two decades, he’s not the chosen one.

Joy Boy, hinted to have fire powers, was expected to reveal himself in Wano. Kaido, with his Dragon powers, thought Ace, who promised to return to Wano and defeat him, was Joy Boy. Kaido left Marineford not to avoid a fight but to save Ace for a Wano showdown. However, Shanks intervened, possibly convincing Kaido that Ace wasn’t Joy Boy; Luffy was.

Shanks seemingly sacrificed Ace to make Luffy Joy Boy, explaining his intervention after Ace’s death but before Luffy’s demise. Shanks waited for Ace to die, believing it was necessary for Luffy’s growth and awakening as Joy Boy.
