Game:Zack

Zack appears as a boss in both Aqua and Terra's storyline, fought at the Olympus Coliseum. In Terra's story, he fights Zack twice, once when Zack wears his helmet, and then again to free him from the darkness, which was caused by Hades in order for Terra to use the power of darkness. In Aqua's story, she fights him as the final opponent in the coliseum's tournament.
