Sabo has always been an interesting character in the story of One Piece. Seemingly coming in out of nowhere in Luffy’s flashback, Sabo quickly became a fan-favorite character and filled a vital role in the series that had been empty ever since the death of Ace. For many, Sabo, while he isn’t a replacement for Ace, felt like a true successor to his character, both in the canon and in terms of storytelling.
