Bio: Cancer was a later addition to the Zodiac. Another background member of the team, Cancer said nothing and stayed mostly behind the scenes. He was killed with the rest of the Zodiac by Weapon X.
Cancer possessed superhuman strength, wore armor, used claws, and carried a Zodiac teleportation device.
Notes: In his original appearance, it was hard to tell if Cancer was a man in a crab suit, or a real man-crab. Weapon-X II#1 confirmed him to be a man in a crab costume. (although depicted him with hands rather than claws, walking like a knuckle-dragging oaf)
