Warp Darkmatter hijacks a cargo ship which is carrying NOS-4-A2's coffin and Team Lightyear comes to stop them.

While fighting NOS-4-A2 with Buzz, Space Ranger Ty Parsec gets bitten by an energy vampire and he turns into the Wirewolf.

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...).

After being bitten by NOS-4-A2 on the mysterious planet of Canis Lupus, Ranger Ty Parsec is transformed into a Wirewolf (...imagine a form of lycanthropy blended with either Star Trek's Borg techno-virus, or with Transformers' Key to Vector Sigma...) [this whole bit is shown in summary, as if it were reminding us of an earlier episode...except there IS no earlier episode about this as far as I can tell]. Even though the transformation only takes place when on or near Canis Lupus, Commander Nebula decides to boot Parsec from the Space Rangers for his own, and everyone else's, good. While this meeting is wrapping up, NOS-4-A2 and XL show up. They have a chunk of Canis Lupus, that causes Parsec to re-transform into a Wirewolf, and they kidnap the en-cursed Parsec. [...the ""Monster""-bit in the title refers to how Parsec is pretty much a robotic werewolf, XL is pretty much a robotic Frankenstein's monster, and NOS-4-A2 is a robotic vampire...] With Parsec
