Personality: Thick headed and childish. Due to his upbringing, Zack has little worldly desires and simply enjoys life. However, this also causes him to almost never take things seriously.
History: 22 years ago, an old hermit named Gohan found a young child floating in a basket down a river. The old man took in the child, seeing it as a blessing and that's how it had been for Zack. He grew up with his "grandfather" living happily in the mountains. However, around the time he was 17, Gohan was visited by an old friend by the name of Sharkie Chan.
A half-man, half-shark creature, he found Zack to have a large, untapped supply of Geki and under Gohan's consent, began training him. Now it has been several years later, and Zack is older and stronger. Wiser however is a different subject. He has long since become the Red GekiRanger but hasn't been introduced to the others. Instead Sharkie instructed him separately so Zack could continue his way of living. It's because of his pure heart that when Sharkie and Gohan allowed Zack to join SGS, they gave him the Super GekiClaw. It's said to give one great power but Zack still hasn't figured out how to use it.
