Turbo K.O.

"No. Not K.O anymore. It's Turbo K.O. T.K.O. for short."

- T.K.O. introducing himself "You think you'll ever be a hero without me? Heh, heh. Face it K.O., i'm stronger! Faster! And if we're being real, cooler than you! Fact is, you need me. Now get up and get back to your cage, faker!"

- T.K.O. fighting K.O. Turbo K.O., or T.K.O. for short, is a major antagonist in ''OK K.O.! Let's be Heroes.'' He is the sentient concentration of K.O.'s anger and frustration as well as his greatest fear.

He is voiced by Courtenay Taylor, who also voices K.O.

Face Your Fears
In "Face Your Fears", in order to help Mr. Gar face his fear of Laserblast, K.O. decides to summon a "powerful villain" and unleashes a dark purple blob that takes his form. When asked by Enid, K.O. describes the blob as being what came out of him last time he played the Face of Fear game, guessing that what ever it is must be his greatest fear. After the blob destroys Laserblast, K.O. lets it back into his brain, stating that he'll see it again in his nightmares.

T.K.O.
In "T.K.O.", after feeling weak, unappreciated and not respected by Enid, Rad and Mr. Gar, K.O. decides to take a shortcut to power offered by a robed man called "Shadowy Figure". In the woods, Shadowy Figure then explains that, in order to become powerful, K.O. must harness his anger and hatred. While this initially fails, K.O. grows even more frustrated and is able to unleash and grow his anger to the point where it takes over his body and imprisons his real personality. As Enid, Rad and Gar's Bodega are about to be destroyed by a blast from Mega Darrell, K.O. arrives and destroys him in a single strike. When Enid congratulates K.O. for saving them, he states that he now referrers to himself as Turbo K.O., or T.K.O. for short.

The next day, while Carol is driving T.K.O. to work, she states that they should talk about K.O.'s new form, only to be ignored. In Gar's Bodega, T.K.O. mops the floor in a lazy and uninterested fashion and refuses to acknowledge his friends, making Enid and Rad realize that their is something off about him. The two then try to make K.O. happy, however, when Enid calls T.K.O. "cute", he snaps and challenges them to a Power Battle. T.K.O. then attacks his coworkers, punching Rad out of the store and into orbit and chasing Enid on to the roof. Rad, having fallen back to Earth and nearly broken his skeleton, attempts to stall T.K.O. while Enid formulates a plan, although T.K.O. breaks through his telekinetic hold and slams him into the pavement. Enid then summons Carol, who attempts to talk T.K.O. down, however, T.K.O. only gets angrier and smashes the sign to the Bodega. Mr. Gar then arrives and, being coaxed by Carol, reveal that he truly values K.O. as both a hero and an employee, although T.K.O. only gets more frustrated, stating that Gar's compliments no longer have any meaning to him. T.K.O., now angrier than ever, unleashes a powerful energy wave that knocks everyone to the ground. As T.K.O. prepares to strike Carol, he punches himself in the face and is sucked into his mind.

In his mind, K.O. reveals that he had escaped his imprisonment and begins fighting with his dark self. Before long, T.K.O. begins beating down on K.O., stating that he will never be a hero without him and that he is superior to him in every way. K.O., remembering what his mother had taught him about the path to power, forgets his anger and focuses, managing to avoid T.K.O.'s attacks, re-imprison him and take control of his body again.

Powers and Abilities

 * Superhuman Strength: T.K.O. is immensely strong, quite possibly the strongest character in the series seen so far. At a base level, he is powerful enough to destroy both Mr. Gar's fear of Laserblast and Mega Darrel in a single blow, both of which being far more powerful that K.O. himself. Additionally, the angrier T.K.O. gets, the stronger he will become. While how strong he can get is unknown, at best, he was able to single-handedly beat Enid, Rad, A Real Magic Skeleton, Brandon, Carol, and Mr. Gar all at once.
 * High Combat Proficiency: T.K.O. is an incredibly skilled fighter, being able to keep up with and surpass foes who had arguably more combat experience and were better at forming combat strategies. He is also shown to be a match for K.O. when the two fight, blocking and countering almost all of his attacks blow for blow.
 * Electrokinesis: T.K.O. can generate electricity from the palms of his hands and use it to both attack and lift himself into the air.
 * Ergokinesis: T.K.O. can fire extremely powerful blasts of energy from his hands. Once he becomes mad enough, he can unleash incredibly powerful energy waves that can knock even Mr. Gar and Carol, two of the most powerful fighters in the series, to their knees.
 * Teleportation: Inside K.O.'s mind, T.K.O. had the ability to teleport short distances.

Trivia

 * T.K.O.'s rage based strength is likely a parody of/homage to various rage based transformations seen in multiple anime and video games.
 * As implied by the ending of "T.K.O.", T.K.O. will likely return in the future, as Shadowy Figure seemingly has a plan that either involves or revolves around him.
