Changes

* Yusaku is the first protagonist since Yusei to use [[Normal Monster]]s in his Deck.

* Yusaku is the only protagonist:

** Who has never lost a Duel to another human.

** To have neither of his parents, or any family, seen or mentioned at any point.

** Who never participated in a tournament or [[Tag-Team Duel]] (unless Yusaku fighting Bit and Boot, 2 Duelists in 1 body, counts in the case of the latter).

* Yusaku has several similarities to Yusei, despite having a much harsher demeanor than the latter.

** Both have "Fu" as the first part of their surnames.
