My vote is that he's an original character for Dissidia based on the original game and not the remake. Dunno what Square Enix's stance is, though. According to the Dissidia Wiki his standard look has him looking like Ingus while his alternate look makes him look like Luneth.
He's just based of the Onion Knight class in the original FFIII. The original SNES version of FFIII had no main characters, it was just four generic warriors. They attempted to give Onion Knight a personality in Dissidia, so I guess he's an original character in a sense. 04:27, January 5, 2012 (UTC)
