T.K.O. is one of three super-powered mercenaries hired by The Shredder in Teenage Mutant Ninja Turtles Adventures: The Year of the Turtle, along with her brother Psonic and Cyberius. Shredder hired the three mercenaries after the rest of the Foot Clan is wiped out by tribal warriors. T.K.O. normally stands for "total knock out", but in this case is also a play-on-words of her special ability of telekinesis. T.K.O. is able to manipulate objects with her mind, as well as create a telekinetic bubble in which she could encase herself and her brother in and use it to levitate themselves.
