He was once exploring a sea cave, when he discovered a toa stone, and was transformed by it. He returned to his village, and asked to be its protector. The village leader obliged, and Zanax protected the village for years.
He once went deep-sea diving, and found a mech suit at the bottom of the ocean that ennhanced his capabilities by making him taller, faster, stronger, and more heavily armored.
He was once exploring a Ta-Koro lava tube, when he discovered a strange, black sword wedged in a stone in the middle of an intersection of tubes. He pulled it out to discover that it was the legendary Blade of Strife. It allowed him to shoot fire from his hands, and could shoot flames or energy from the sword.
He is currently in Bara Magna, fighting against the Skrall rebellion with his team.
Zanax wears the Kanohi Gylvex, the mask of teleportation. He can control, create, and absorb water, fire, and he can move objects with his mind because of his suit.
Bionicle is owned by Lego, Zanax is my personal creation
