Ranger Ty Parsec has been assigned patrol duty on Canis Lupus, guarding a special Galactic Alliance power station that converts radiation from the planet's strange green moon into usable energy. Ty laments the boring responsibility, unaware that NOS-4-A2 is lurking nearby and stalking his robot teamate. When the energy vampire strikes, Ty informs Star Command but insists no backup is required. It arrives anyway in the form of Team Lightyear, much to Ty's chagrin. Ty has been rescued no less that 50 times by Buzz and is sick of being put in that position.
During their next patrol, Ty saves XR from NOS-4-A2, but requires Buzz to save him. The vampire is driven off but not before accidentally biting Ty through the flesh. This puts a werewolf-like curse on Ty who is changed into a robot-ravaging ""wirewolf"" when exposed to the strange moon of Canis Lupus. Team Lightyear and Ty himself are unaware of the periodic transformations. The wirewolf eludes a trap, shredding XR in the process
