T.K.O.

T.K.O. is one of three super-powered mercenaries hired by The Shredder in "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.

While Cyberius and Shredder were locating the exact spot in which the mystical energies of the Turtle Constellation would be transferred to the Green Talisman, T.K.O. and Psonic went to Tibet to retrieve the Talisman's final piece. T.K.O. activated the Talisman piece at the same time as Michaelangelo; the resulting reaction knocking T.K.O. out cold, as well as demutating Michaelangelo back into a regular turtle. T.K.O. soon recovered, and retrieved the Talisman piece back from the Turtles, but was paralyzed by a nerve pinch from Hamato Yoshi.
