After being forcefully dragged into the Moby Dick by the Whitebeard pirates, Ace had done nothing but rebel against Whitebeard himself, trying to kill the man time after time without a stop, and each time, he failed miserably regardless of what his plan was.

He had been offered a place here, but he found it utterly ridiculous how everyone claimed Whitebeard was a father to all of them.

He didn't needed a father, he was fine by himself and his crew, nothing else.

And he didn't appreciated how everyone tried to get him to join the Whitebeard pirates.
