Buzz Lightyear’s adventures as he patrols the galaxy with his team of Space Rangers, battling evildoers “to infinity and beyond.”
XR downloads Star Command Mainframe to prevent the system from crashing (due to Warp Darkmatter using info-stealing techno-ticks); Zurg heists XR in order to gain Star Command classified information; XR uses techno-ticks to help HIM out.
Petra, a senator's daughter, is shipped off to Space Ranger Academy to keep her from Plasma Boy; Booster falls for her; both Petra and Plasma Boy end up in Space Academy.
While fighting NOS-4-A2 with Buzz, Space Ranger Ty Parsec gets bitten by an energy vampire and he turns into the Wirewolf.
Zurg hits Mira & Buzz with gas that melts & melds them into a shoggoth-like creature, then sends them on their way back to Star Command; Mira/Buzz accidentally infect all of Star Command upon their return.
Cosmo gets K-3000 Uni-appliance for Cosmo's Diner (the diner that Team Lightyear seems to spend too much time at); the K-3000 Uni-appliance is an experimental device that absorbs one's kitchen appliances into itself, and is able to use them all due to its powerful, experimental energy source and its ""liquid steel"" structure (...possibly constructed of nanobots?...very much like a robotic shoggoth, from H.P.Lovecraft's stories...). NOS-4-A2 senses the power within the K-3000 when the Courier delivering it passes close to the abandoned ship that he was residing in, trails after it, and takes control of the K-3000, all of Cosmo's restaurant equipment, and then all of Cosmo's Diner. Team Lightyear is in the process of returning Professor Triffid to his home planet, Rhizome, after a failed attempt on his part to convince Star Command to incorporate ""organic vegegenetic technology"" into their systems, when they receive the distress call from Cosmo.
After investigating a rash of robo-homocides, Team Lightyear discover that NOS-4-A2's loose on TradeWorld with a self-appointed ""slayer"" on his floating tail -- Savy SL-2, a human orphan that was adopted by a robot couple. NOS-4-A2 had ""vamped"" her adoptive parents, so she decided to step in as a vigilante vampire-robot-slayer (...a la Buffy...). With her assistance, they hunt down NOS-4-A2, fight his horde of enslaved robots, and defeat him, freeing those robots that were in the grip of his dark forces (...including XR who, as usual, was an easy mark for NOS-4-A2...).
