The Slayer

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 SL2, a human orphan that was adopted by a robot couple.  NOS-4-A2 had drained her adoptive parents, so she's decided to step in as a vigilante vampire-robot-slayer. 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.
