Nos-4-A2 is an antagonist who appeared in Buzz Lightyear of Star Command. He was a robotic energy vamipre created by Emperor Zurg as a way to defeat his nemesis Buzz Lightyear.

He was voiced by Craig Ferguson.


Nos-4-A2 first appeared in the episode "NOS-4-A2", where he was mistaken for a cargo ship by Team Lightyear and brought over to Star Command, as part of Zurg's plan to take down Star Command. There, Nos-4-A2 emerged and attempted to take over Star Command, but XR manages to drain the vampire's energy, allowing Star Command to take Nos-4-A2 into custody. However, in "The Slayer", he escapes to Tradeworld, where he kills the adoptive robot parents of Savy among several other robots and plans on getting revenge on XR for foiling his plot, though this too failed as well.

In the episode "Wirewolf", Nos-4-A2 cross path with Space Ranger Ty Parsec and bites him, turning Ty into Wirewolf. In "Revenge of the Monsters", he recruited XL on his new plot to take over the universe by turning everyone into Wirewolves. To that end, Nos-4-A2 betrays Zurg by usurping control of Planet Z and turning all of Zurg's army of Hornets into Vampire Hornets. He then kidnaps Wirewolf as a means to use him to turn everyone in the galaxy into Wirewolves for himself to feast on, using Ty to power a weapon which drained him of his energy in a painful process. When XL realized he would also be consumed, he defected and helped Buzz and XR. He was later defeated when Wirewolf turned against him after being freed by Buzz Lightyear and XR, where he was impaled and exploded to his death while screaming.


  • He is the only Toy Story villain who actually permanently dies, as well as onscreen.
  • His name is an playful yet allegorical pun on the name of the famous vampire film Nosferatu.
