Tretista Kelverian

Tretista Kelverian (トレテスタ・ケルベリアン) is one of the bosses in Mega Man Zero 3. Tretista is based on Cerberus, the three headed hellhound. He is one of the Eight Gentle Judges, and has three independent thought circuits that he uses to reach a fair judgement. When Dr. Weil brainwashed him to be one of the Weil's Numbers, he could not think properly, becoming violent and arrogant. During a mission, Zero went to investigate a giant elevator created by Neo Arcadia, and he finds Kelverian protecting it, fighting against him. Zero them discovers the elevator is used to transport mass amounts of E-Crystals to be used as energy. Kelverian reappears in the final stage, but is defeat again by Zero.

Tretista attacks by seperating the dogs attached to his shoulders, throwing a box and then dash to destroy it, spitting energy balls across the floor, and bending a metal bar into a V shape and them toss it as a boomerang. At A or S rank he will use his EX attack, where a large laser comes from his claw in some of the times he dashes to a box. Defeating him gives Zero the Absorber Body chip and, if at A or S rank, the Gale Attack ability.
