Nos-4-A2 was a villain who appeared in Buzz Lightyear of Star Command. Nos-4-A2 was a robot who was created by Emperor Zurg as a way to defeat his nemesis Buzz Lightyear.
He was capable of controling other machines that are powered by biting them. He was vampire like in appearance, and even "slept" in a coffin.
He was, however, more conniving than Zurg, and planned on ruling the universe. In one episode, he bites Ty Parsec, and turns him into a Wirewolf.
He planned on turning the universes' inhabitants into machines for him to snack on. He was later defeated when his Wirewolf turned against him. He was later impaled and explodes while screaming.
