When a fighting tournament is announced at the Plaza, there is more at stake than meets the eye.
Tropes
- All for Nothing: POW Card Levels have variously been shown as quantifying raw power, overall ability, or fighting experience/accomplishment, something that K.O. had strove for since the start of the series. Carla comments that T.K.O. destroying the servers that kept their data doesn't really matter because the rankings made no sense in the first place.
- Back for the Finale: While all of the normal Jethros were destroyed by T.K.O., the more intelligent Jethro 2.0 from "I Am Jethro" returns with Lord Boxman to help Boxbot Prime against T.K.O..
- Beat the Curse Out of Him: When Shadowy Venomous reveals that he was only ever using T.K.O., the latter punches him with his power-draining fist, knocking the blob that is Shadowy Figure out of Professor Venomous and destroying it (thus accomplishing this for good).
- Big "NO!": Fink right as T.K.O. is about to power-drain her now-restored "boss"; then Venomous does this after she takes the shot for him and is drained/killed.
- Boss Subtitles: Turbo Rad (Trad) and Turbo Enid (Tenid) get these; “Ultimate Teens (This Might Not End Well)”
- Broken Tears: T.K.O. sheds them after he looks around and sees that he's killed everyone. The newly-merged K.O. does so as well, until the President shows up to fix things.
- Continuity Nod: The episode ends with K.O. facing Cowboy Darrell and the two doing a Punch Parry, just like in K.O.'s fantasy sequence in the very first episode "Let's Be Heroes!"
- Deus ex Machina: The President of the Universe gives K.O. a wish for winning the tournament. K.O. uses it to wish that everyone gets to live their best life, putting everything back to normal.
- Disney Death: Just about everyone in this episode gets one except for Shadowy Figure (who's Killed Off for Real), courtesy of T.K.O.. Dendy, Boxman, and the Boxmore bots are flung into Cool Sun, which destroys them all, and T.K.O. de-powers (and thus kills) everyone else in the Plaza. However, once K.O. is given his tournament wish from the President of the Universe, he wishes for everyone to live their best lives, which restores them all to life again.
- The Dog Bites Back: T.K.O. takes down Shadowy Venomous after finding out that he was just using him for his plans.
- "End of the World" Special: After (T.)K.O. drains (and thus kills) everyone else on Earth, he uses his wish for winning the tournament to restore everyone and give them their best life.
- The End: The episode ends with a Pastel-Chalked Freeze Frame on K.O. and Darrell's Punch Parry with "the end" written over it.
- Enemy Mine:
- Fink offers assistance to Rad and Enid to beat T.K.O. by giving them glorbs and glorb collars, though sadly, they still lose (and return back to normal) once T.K.O. begins drawing on the power of the glorb tree.
- Dendy works together with Boxman and Boxbot Prime to try to beat T.K.O., though they, too, unfortunately fail.
- Face Death with Dignity: Professor Venomous when T.K.O. is about to kill him with his energy-draining power, just smirking in acceptance and saying "Do your worst, kid." Though he quickly starts panicking once Fink does her Heroic Sacrifice to protect him.
- Godzilla Threshold: Enid and Rad accept Fink's offer to use the power braces to become Turbo, resulting in "Trad" (Turbo Radicles) and "Tenid" (Turbo Enid).
- Hoist by His Own Petard: Shadowy Venomous uses the Lakewood Tree to give T.K.O. the ability to drain the power and energy of everyone on the planet. However, when he pisses him off by revealing that he was just using him all along, T.K.O. punches him with his fist while still using this draining power, causing Shadowy Figure to be extracted from Venomous where T.K.O. can destroy him for good.
- Hope Spot: When Rad and Enid go Turbo to fight T.K.O., they're at first doing much better than they were before, but he soon manages to overwhelm them anyway, then Shadowy Venomous activates the Lakewood Tree, and then their collars break and they're powered down from their Turbo forms. As awesome as it looked at first, in the end, they didn't actually manage to accomplish anything at all by going Turbo.
- "I Know You're in There Somewhere" Fight: K.O. is indeed in there, and is trying to get out. However, none of his family's or friends' attempts to reach him manage to snap T.K.O. out of it. The one thing they do succeed in with this trope is making his drain-dome falter long enough to cause T.K.O. and Shadowy Venomous to have a falling out, leading to the former defeating the latter and killing Shadowy Figure for good. But then right after this, T.K.O. power-drains everyone there, and anyone else's attempts to stop him are futile. Only K.O. himself is able to get through to him, and calms him down just by accepting him, and acknowledging that they are both the "real" K.O.
- Killed Off for Real:
- Mr. Cardsley somehow died prior to the episode (presumably killed by Shadowy Venomous and T.K.O. when they attacked POW Card Industries), leaving his former assistant Carla to take over as CEO.
- Shadowy Figure is extracted from Venomous' body by T.K.O., reducing him to a mere dark blob, and then squashed flat, permanently destroying him.
- Kill the Ones You Love: In T.K.O.'s draining rampage, the final people he de-powers are Carol, Gar, Rad, and Enid, who can only huddle together in comfort as T.K.O. blasts them. He's left in tears after he does so.
- Late to the Tragedy: This happens when the President of the Universe appears to congratulate K.O. for winning the tournament, but didn't realize that his other personality T.K.O. had vanquished everyone on the planet leaving it desolated and making K.O. feel miserable. Fortunately, K.O. gains a wish from the President to make things better, not only restoring everyone, but allowing them to live their best life.President of the Universe: How's it feel?K.O. (miserable and crying): Terrible!President of the Universe (understanding the situation): That's not very groovy.
- My God, What Have I Done?: The now-merged K.O. has this when he regains consciousness and realizes that T.K.O. drained (i.e. killed) everyone, friend and foe. Thankfully, it's fixed in short order by the President's arrival.
- Never Say "Die": What T.K.O. does to everyone on the planet is referred to as "de-powering" or "draining" by the characters, likely for censorship. However, considering that he says he's going to "de-power everyone so thoroughly, there won't be a speck of energy left", it's pretty obvious that he's outright killing them, which
Word of God confirms. - No Body Left Behind: Everyone that T.K.O. de-powers and drains of their energy at first just looks like they've had their color washed out, but then they completely dissipate (mostly offscreen) afterwards, so rather than being surrounded by corpses after stopping his rampage, T.K.O.'s just all alone in the Plaza.
- Not Quite Back to Normal: After K.O.'s Split-Personality Merge, he now looks mostly like he did for most of the series, but with slightly messier hair and the visible canine of T.K.O.—essentially P.K.O. without the color change or irises. This would carry onto the next and final episode.
- Not Quite the Right Thing: K.O. realizes that his treatment of T.K.O. has always been this:K.O.: We had a way to control our anger, but we buried it! I'm so sorry! [...] T.K.O., even when I accepted you as part of me, I thought you were just this angry thing that got put in my mind by somebody else. I locked you in a cage, I put you in that dumb house, I tried to get rid of you! But the more I tried to treat you like someone else, the worse it got. I'm ready to accept the truth. You're not just a part of me, T.K.O.! You are me! And I'm you!
- Now You Tell Me: Dendy is exasperated to find out that the Boxmore robots knew about Shadowy Venomous's plan for the tournament and taking over the universe for quite a while, but only bothered to bring it up when Rad and Enid were discussing their disinterest in participating in the tournament.
- Penal Colony: Played out after K.O. makes his wish to make everyone live and make things better, The President of the Universe teleported Professor Venomous and Fink to another planet where they happily rule and destroy everything as they want ...at least for the moment.
- The Power of Love: K.O.'s family and friends try to use this to bring him back out of T.K.O. This time, though, it doesn't work, and only K.O. himself is able to stop T.K.O.'s rampage.
- The Reveal: The President of the Universe put glorbs in K.O.'s world to give everyone powers and Toon Physics, and thus make it more fun.
- Senseless Sacrifice: Fink's Taking the Bullet for Professor Venomous doesn't actually accomplish anything, since T.K.O. just drains/kills him right after her anyway. She knew this was the case, though, and it was more just for the sake of her Undying Loyalty to her boss than anything else.
- Shout-Out:
- While showboating, T.K.O. does the infamous John Cena "You Can't See Me" hand wave in front of his face.
- The way K.O. deals with T.K.O. (by accepting that he's a part of himself) is reminiscent of Shadows in Persona. K.O. even tells T.K.O. "I'm you, and you're me!"
- So Proud of You: The President of the Universe towards K.O., noting that while some people just want to take the fun out of everything, K.O. wants to bring people together and let everyone to live the most fun, happy lives they can, and in his eyes, this makes K.O. the truest hero he ever did see.
- Soundtrack Dissonance : This happens when K.O. (who is trapped in his own subconsciousness) uses an old toy tape recorder to calm down T.K.O., which contains a song Carol sang to him when he was a toddler. This cheerful, upbeat song is playing in T.K.O.'s head as he is shown power-draining (i.e. killing) everyone in the Plaza.
- Split-Personality Merge: K.O. and T.K.O. undergo this for good once K.O. finally accepts that he and T.K.O. are each other, just two sides of the same coin rather than a monster inside him that someone else created. The merged version of K.O. pretty much looks like P.K.O. without the color change in his irises and sweatbands.
- Sweat Drop: Rad notes that T.K.O. hasn't even broken a sweat. At that moment, a sweat drop does appear on T.K.O.'s head... but he sucks it back inside, with the drop screaming in pain.
- Theme Tune Extended: The montage of T.K.O., Enid, and Rad advancing in the tournament is set to a longer version of the show's theme song.
- Taking the Bullet: Fink does this for Venomous when T.K.O. is about to use the power-drain on him first. It doesn't really make a difference considering he still drains him right after draining her, but Fink, despite knowing this, still does so anyway, noting that she wouldn't be much of a minion if she didn't stand by Venomous till the end.
- Tomato in the Mirror: K.O. realizes T.K.O. is not something Shadowy Figure created or even another person inside him—he is K.O. as much as his "normal" personality and always has been. This realization causes a permanent Split-Personality Merge.
- Undying Loyalty: Fink to Professor Venomous (the real one, not Shadowy Venomous, whom she does not work for because she knows he's basically just Shadowy Figure). As T.K.O. is about to drain/kill him, she jumps in front of him as a human shield, even when Venomous tells her to run away as it's pretty obvious that she's not going to actually save him by doing so (it just means T.K.O. will drain her first), she still refuses to leave him, stating that she'll stand by his side to the very end.
- Villainous Breakdown:
- Shadowy Venomous has one when the entire crowd is cheering for K.O. and T.K.O.'s draining-dome starts to falter. When the two of them argue about this, T.K.O. notes that he's the one who actually has the power and is doing the work, making Shadowy Venomous completely lose his temper and reveal that he was just using T.K.O. and plans to have the latter do his bidding once they accomplish his plans. This causes T.K.O. to beat him out of Venomous and destroy him.
- T.K.O. has one while draining everyone when K.O. plays the recording in his mind of Carol singing a song from their childhood, repeatedly yelling to make it stop and bringing him to tears after he drains his family and best friends. K.O. gets the chance to calm him down as a result.
- Wins by Doing Absolutely Nothing: The fight between Dogmun and Invisible God Aquarius (a giant eye) amounts to a Staring Contest, which ends with Aquarius blowing up. Whether Dogmun caused the explosion somehow or simply stood by as Aquarius overexerted himself is left unexplained.
- You Were Trying Too Hard: One possible explanation to why Invisible God Aquarius explodes during his fight with Dogmun. That or Dogmun somehow Caused the explosion.
