But he's primarily based on his appearance in the original Zelda, and large parts of his moveset were adapted to fit the platformer style. His jump was made higher than in any platformer he's appeared in, for one. And he wasn't the only character who had to be changed, either. Castlevania never really focused on platforming as much as combat, so Simon's jump had to be adjusted. Ryu became able to climb any wall. That's just off the top of my head, too, I'm sure there would be more changes if I looked closer.
