Ty Parsec was a Space Ranger who always stood in the shadow of his colleague, Buzz Lightyear. One fateful day when on duty on the deserted radioactive moon, Canis Lupus, he accidently ended up getting bitten by NOS-4-A2. That, plus the power of the moon, turned him into a wirewolf (a robotic werewolf) when in contact with the rays of that moon. Canis Lupus was eventually blown up, but NOS-4-A2 used a chunk of the moon to turn Parsec into the wirewolf a second time. Parsec was used to briefly turn Capitol Planet's population into wirewolves, but the curse of the wirewolf was ended thanks to Team Lightyear.
