Voiced by: Kari Wahlgren

Shy Ninja's main enemy who resembles a demon of sorts and has cloud-based powers. Also one of Lord Boxman's investors for his company.

Hero Level: -6

  • Arch-Enemy: Is this to Shy Ninja.
  • Bad "Bad Acting": In the "Boxmore Infomercial" short, she is obviously reading aloud her lines from a cue card, judging by the poor inflection and random pauses in her dialogue.
  • Early-Bird Cameo: Vormulax first appeared in the short, "Boxmore Infomercial", and made an official appearances in "Know Your Mom".
  • Fangs Are Evil: Has a mouth full of sharp teeth.
  • Go-Karting with Bowser: She was one of the Plazalympics judges in "Plazalympics" among Mr. Gar and Carol.
    • In "Dendy's Power" neither K.O. nor Dendy show any aversion to her presence when she wants her POW Card customized, strangely enough K.O. does get bothered by Shannon.
  • Our Demons Are Different: Has a cloud motif. Described as a alien-esque ghoul.

Voiced by: Jonathan Davis

A retired member of a gang of humanoid cacti called the "Kactus Krew" until Carol, under the name of Silver Spark, single-handily took down the gang.

Hero Level: Unknown

  • Adam Westing: He's a parody of aging Nu Metal stars voiced by Jonathan Davis of Korn, the band that essentially invented the genre.
  • Go-Karting with Bowser: He at first comes to a showdown with Carol, but he's too old and gets winded too easily. Carol invites him to a cup of coffee and start reminiscing about the old times.
  • Feeling Their Age: Because he's so old and hasn't fought in years, he's easily tired during his fight with Carol, who isn't having any trouble with him at all.
  • Green Thumb: He has the power to grow cacti from the ground.
  • Magic Staff: He uses his staff to fight and to summon cacti from under the ground.
  • Plant Person: Of the cactus variety.
  • Retired Monster: He's a former member to a group of villainous cactus people. However "Villains' Night Out" shows that he may not be entirely retired as he attends Billiam Milliam's party
  • Rotten Rock & Roll: A villain with a(n aging) rock star theme. His gang was also a popular rock band, as a Kactus Krew song plays on the radio.
  • Waxing Lyrical: 90% of Succulentus' lines are from lyrics to songs by various early 2000's Nu Metal acts like Korn, Linkin Park, System of a Down and Evanescence.

    Shadowy Figure
Voiced by: Steven Ogg

A mysterious man who wants to unleash K.O.'s inner power.

Hero Level: -8

  • Affectionate Parody: Of the Knight of Cerebus concept. His seriousness is written in a primarily tongue-in-cheek manner, and often jars with how strange the other castmembers are, but it doesn't stop the episodes he appears in from being much more story and character-based.
  • Amazing Technicolor Population: Has a grayish-purple skintone.
  • Ambiguous Situation: In "Carl", he claims that he and Professor Venomous reached an "agreement" and did a Split-Personality Merge, but his Boss Subtitles as Shadowy Venomous seem to imply that something else entirely is going on. Since Shadowy Venomous's appearance, characteristics, and behavior are pretty much the same as Shadowy Figure's, it's heavily suggested that this "agreement" entailed Venomous willingly giving up control of their body to Shadowy because it would make them more powerful.
  • Art Shift: He's usually drawn in the same style as the other characters, but will occasionally shift into a more Animesque art style.
  • Arch-Enemy: He's K.O.'s most personal enemy and knows more about him than any other villain. K.O. is visibly uncomfortable even speaking about him.
  • Badass Longcoat: Wears one of these combined with a Scarf Of Asskicking.
  • Big Bad: While a recurring threat throughout the series, Shadowy doesn't step into the Big Bad spot until season three, where his identity and agenda are finally revealed.
  • Big-Bad Ensemble: With Boxman and Venomous for the entire show. He doesn't appear as often but his actions have long-term consequences, the creation of T.K.O. being the most significant. As it turns out, he's the turbo form of Professor Venomous, who wasn't aware of it himself. Shadowy's goals are ultimately much more personal to K.O. and have little to do with Venomous and Boxman. In fact, once Shadowy gains full control, he's quick to oust Boxman and take the Big Bad title for himself fulltime.
  • Black Cloak: Wears a light black trench coat.
  • Boss Subtitles:
    • Unlike many other characters in the series who get these for their first significant appearance, Shadowy Figure doesn't receive his until "Let's Get Shadowy" (his fifth episode appearance), when K.O. and the audience finally see his full face (with the hood off) for the first time.
    • Gets some very long ones when he finally gains complete control of the body he shares with Venomous:
  • Bullying a Dragon: Shadowy Venomous pushes his luck when he starts manhandling T.K.O. (who was saturated with glorbs by this point) for backtalking him. T.K.O. doesn't take the abuse well and dispatches him with one blow.
  • Casting a Shadow: When he merges with Venomous, he obtains a distinct purple-black aura that vastly powers up his attacks and can manifest as Fog Feet that gives him flight.
  • The Comically Serious: He always acts serious, but some of his behavior is still quite silly, like sneaking around the Plaza at night, asking K.O. with a completely straight face if he needs to "potty", or dramatically standing on a roof, even as someone asks him what he's doing.
  • Darth Vader Clone: He dresses in all-dark clothing, speaks in a deep, metallic voice, and appears to have an unknown connection with the protagonist. Fittingly, he also shares this with his host personality Professor Venomous; Shadowy embodies the more "Vader"-like aspects, while Venomous has the "Anakin"-like aspects.
  • Don't Tell Mama: Shadowy actively kept Venomous from finding out they were one and the same, and blackmailed Fink into keeping silent, lest he take over for good.
  • Dramatic Unmask: He's finally shown without his hood on (Boss Subtitles included) in "Let's Get Shadowy". An interesting variation in that the audience and characters already know who he is at this point (the Turbo alter-ego of Venomous), but it's still a genuinely dramatic and frightening moment since, by his own desire, we've never seen what he looks like, and the fact that Shadowy kept his hood off after transforming this time is indicative of his rage at being exposed.
  • Eviler Than Thou: For Boxman and even Venomous. Whereas Boxman is more of a classic back-and-forth type villain, Shadowy Figure would rather wipe his enemies off the map completely. Boxman even labels Shadowy as more of a monster than a villain. Meanwhile, Venomous, despite his past issues, was able to find a fulfilling life as a villain, but Shadowy is his desire for more power incarnate, to the point he aims to de-power everyone else so he's the only one with power.
  • Evil Mentor: He pretended to be K.O.'s friend in order to fill him with anger.
  • Evil Sounds Deep: With a metallic effect for good measure.
  • Exactly What It Says on the Tin: As his name implies, he's a shadowy figure.
  • Fangs Are Evil: Has a mouth full of sharp teeth.
  • Greater-Scope Villain: "Let's Get Shadowy" reveals he was Foxtail's glorb supplier during the second season's P.O.I.N.T. Prep arc.
  • Hidden Agenda Villain: He wants to unleash K.O.'s inner power, but his motivation for this is unknown until the end of the series, let alone why he knows so much about K.O.'s inner power in the first place.
    • Lampshaded in "T.K.O.'s House", when T.K.O. questions Shadowy Figure on why he was created, he said he needed him to infiltrate the area under the plaza to obtain the glorbs. T.K.O. doesn't buy it because then he questions why does he know so much about K.O. and why does he always look satisfied when K.O. is winning their fights. Shadowy Figure drops his smug attitude and remains silent, and when T.K.O. temporary loses control of K.O.'s body, Shadowy Figure leaves the area without saying a word.
    • Once we find out in Season 3 that Laserblast is K.O.'s father, Venomous is Laserblast, and Shadowy Figure is Venomous's alter, the interest is all but outright stated to be because he knew all along that K.O. was his sonnote  and probably had his own Turbo form (just like Shadowy is himself the Turbo form of Venomous), and hoped to sway T.K.O. to his side and use him for his own plans.
  • His Name Really Is "Barkeep": "Shadowy Figure" is treated as an actual name, even appearing on his Pow Card.
  • Hoist by His Own Petard/Gone Horribly Right: He spends the whole series trying to get K.O. to unleash T.K.O. to become more powerful (since he wants to use him for his own agenda). He succeeds, multiple times. And then in "Let's Fight to the End", T.K.O. learns Shadowy Venomous was using him and turns on him...and has become so much more powerful thanks to Shadowy's own efforts that he easily defeats and kills him.
  • Identical Stranger: He has the same stature, face structure, and VA as Professor Venomous. With the reveal of what the collar does to Fink looking very familiar to what the Figure was doing with K.O., it looks like there is a bigger connection...
    • ...Which is later revealed in Season 3. Turns out that Shadowy Figure is actually the “Turbo” form of Professor Venomous, something Venomous himself was totally unaware of.
  • In the Hood: He wears a black hooded scarf, the hood's shadow obscuring his eyes.
  • Informed Ability: Shadowy Venomous is said to be more powerful than ever... but he never actually shows it, as he would rather leave all the fighting to T.K.O.. Shadowy's calls for being the most powerful fall flat when a glorb-charged T.K.O. takes him out in one shot.
  • It's All About Me: "Let's Fight to the End" reveals he never cared for T.K.O. at all, and merely saw him as a pawn to de-power everyone else, and leave him as the most powerful being on the planet.
  • Karmic Death: Spends the entire series manipulating K.O. and making him feel weak to get him to bring out T.K.O., whom Shadowy Figure wanted to use for his own plans to become more powerful. T.K.O., who is stronger than Shadowy due to Shadowy's own plans, promptly destroys him for good upon finding this out.
  • Killed Off for Real: After he gets a little too aggressive with T.K.O., he's expunged from Venomous' body, reducing him to a dark blob that T.K.O. easily squashes under his foot.
  • Knight of Cerebus: He tricks K.O. into being a bigger threat to the plaza than even Lord Boxman. While K.O. wins against his anger in the end, Shadowy's appearance at the end of the episode suggests that he's not done with K.O. just yet. He becomes this even more in "Let's Have a Stakeout" when he easily mops the floor with K.O. in their first fight (only losing in the end because K.O. outmaneuvered him during his Villainous Breakdown). From then on, in future episodes, K.O. is visibly uncomfortable and unhappy when talking or thinking about him.
  • Manipulative Bastard: He prefers to manipulate K.O. as opposed to actually battling him, only fighting when K.O. initiates it. He proves to be pretty good at it:
    • In his debut in "T.K.O.", he serves as K.O.'s Evil Mentor by pretending to be a hero who just wants to help him get stronger after overhearing his frustrations. His advice to K.O. to Teach Him Anger and get him to utilize The Power of Hate is what first gives T.K.O. physical form.
    • In "Let's Have a Stakeout", he tricks K.O. into opening the door to the glorb tree room for him by purposely letting K.O. see him and follow him, and then hiding so K.O. thinks he went through the door and breaks it open.
    • In "K.O. vs Fink", K.O. mistakes Shadowy Figure's voice as being his "inner monologue", and Shadowy just rolls with it and "advises" K.O. to defeat his bully (Fink) by unleashing his anger to beat her up (and also comically tries to get him to bring him some glorbs). K.O somehow fails to realize that his "inner monologue" is really Shadowy.
    • One of his best examples of this happens in "Carl". Shadowy Figure has been T.K.O.'s Berserk Button throughout the series for creating him and tricking him repeatedly, and T.K.O. confronts him/Venomous raring to fight. But after revealing that he's overtaken Venomous and become Shadowy Venomous, Shadowy invokes Not So Different and We Can Rule Together, and successfully manages to persuade T.K.O. to partner up with him, despite Shadowy just planning to use him and not really caring about him.
  • Not So Above It All: He shows a much sillier side in "T.K.O.'s House", offhandedly doing absurd things like eating a banana mid-fight or catching the glorbs with a butterfly net.
  • Not So Different: He's this to T.K.O. Both are the dark, powerful alter-egos of K.O. and Venomous, and represent their negative traits. While Venomous was able to find satisfaction in villainy, Shadowy Figure is his insecurity and lust for power given life, much like how T.K.O. is K.O.'s negative emotions and helplessness given physical form. As Shadowy Venomous, he actually invokes this, using the trope name word-for-word, to convince T.K.O. to side with him.
  • Obviously Evil: He's a tall man in a black robe originally obscured by shadow that wants to take K.O. somewhere. The only reason K.O. trusted him was because his Pow Card said he was level 8 (which was actually a glitch, as it's really -8).
  • Significant Double Casting: Triple, in fact. He, Laserblast, and Venomous are all voiced by Steven Ogg. The latter two sound almost exactly the same, and Shadowy sounds a lot like Venomous but with a metallic voice. Turns out this is because all three of them are, in fact, the same person, with Shadowy's metallic voice coming from the fact that he's a Turbo form.
  • Small Name, Big Ego: After he becomes Shadowy Venomous and sways T.K.O. to his side, he starts thinking of himself as the soon-to-be most powerful person in the world, since he plans to use T.K.O. to become this. But T.K.O. is shown to be the one with the actual power who's doing most of the work in their partnership, and when he points this out, Shadowy Venomous furiously manhandles him, makes it clear he never really cared about him, and boasts about how he'll use him to become the most powerful being in the universe himself...when T.K.O., who was probably already stronger than him anyway, has become even more so thanks to being powered up by glorbs. Since Shadowy doesn't have the power to back up his words, T.K.O. easily beats him in one shot and kills him.
  • The Sociopath: He is Professor Venomous's helplessness, resentment, and most of all, his thirst for power above all else given physical form. As a result, he doesn't care about anyone but himself (not even T.K.O., whom he was just using the whole time and only pretending to care about to manipulate him), and that includes the people that Venomous himself does care for, like Fink, Boxman, the Boxmore bots, and possibly even K.O. to some extent. Shadowy just wants to essentially kill everyone in the entire world by draining their powers, just so he can become the most powerful being in the universe.
  • So Proud of You: For some reason, he appears satisfied whenever K.O. beats him, to the point it goes beyond Graceful Loser. T.K.O. even takes note of this and asks why Shadowy Figure feels this way, but doesn't get an answer. It might be because he knows that K.O. is his son, and wants him/T.K.O. to get stronger so he can eventually use him for his plans.
  • Split Personality: Revealed in "Let's Get Shadowy" to be Professor Venomous's alter, created when he was experimenting on himself to try to get his powers back. Unlike K.O. and T.K.O., though, Venomous genuinely had no idea Shadowy existed, and is pretty disturbed when he finds out.
  • Split-Personality Merge: Ends up merging with and overtaking Professor Venomous to create "Shadowy Venomous" (who is, for all intents and purposes, just a more powerful version of Shadowy himself).
  • Split-Personality Takeover: Threatened to do this to Venomous if Fink ever told him about his existence, and seems to have made good on that promise as of "Carl" (though the fact that he claims that he and Venomous had an "agreement" implies that the latter willingly allowed it).
  • Superpowered Evil Side: In this case, Superpowered Eviler side. Him being one villain point higher than Professor Venomous isn't just for show, as he's got shadow powers and doesn't care about anyone but himself or T.K.O. (and even then, only cares about being able to use T.K.O. for his own agenda).
  • Two Aliases, One Character: Make that three since he's Professor Venomous and Laserblast.
  • Villain Ball: When T.K.O. talks back to him in "Let's Fight to the End" and points out that he's the one who actually has all the power, Shadowy Venomous is furious and starts getting rough with him, then begins some Evil Gloating in which he pretty much outright states that he was only ever using T.K.O. for his power the whole time to accomplish his own goal of de-powering everyone else in the world and making himself the most powerful. Unsurprisingly, T.K.O. is pissed, and since Shadowy Venomous doesn't have nearly as much power as T.K.O., the former easily defeats him, knocks him out of Venomous's body, and destroys him for good.
  • Villainous Breakdown:
    • When K.O. stops himself from becoming T.K.O. again in "Let's Have a Stakeout", and declares his intention to make the situation he'd made worse better, Shadowy Figure loses his cool and tries to attack K.O. there and then, and gets knocked off a ledge for his troubles. He does compliment K.O. for managing to best him afterward, though.
    • Happens for pretty much all of the short amount of screentime he has in "Let's Get Shadowy". In all his previous episodes, Shadowy Figure only beat up or got physical with K.O. when the latter started fighting him, but otherwise didn't harm him because he planned to use him in the future. Here, though, he's so pissed that Fink and (unwittingly) K.O. outed him as Professor Venomous's alter ego—something Shadowy wanted to remain unknown to the point that he threatened Fink into keeping it secret—that he viciously attacks and tries to beat the crap out of them both, though they managed to beat him in the end.
    • Also gets one in "Let's Fight to the End" as Shadowy Venomous, causing him to completely grab the Villain Ball. See above.
  • We Can Rule Together: Everything he's done in the series was ultimately for the purpose of making this offer to T.K.O. Shadowy asks him to join him in making the world their own personal playground. T.K.O. accepts.

Voiced by: Michael Leon Wooley

A villain that Hero is on a quest to defeat.

Hero Level: -99

  • Big Bad: He's this in RPG World and Hero is on a quest to defeat him.
  • Motive Decay: After K.O. leaves him and Hero alone, they realized that they forgot why they are fighting. His case is more justified, since he is trapped in his tower and doesn't have any other thing to do but wait for Hero to come and Level Grind.
  • Orcus on His Throne: He's waited in his tower as Hero spent a long time Level Grinding. Since he's a Boss Battle in-universe, he can't leave, or do anything but his own Level Grinding.
  • Sealed Evil in a Can: He can't leave his tower—or even move from the spot he's scripted as standing on for his Boss Battle. Once he and Hero realize they've forgotten what they were fighting over, Hero is free to live his life elsewhere, while Galgarion is stuck in place, and no threat to anyone in the meantime.
  • The Unpronounceable: Hero can never manage to say his name right.
  • Villain Forgot to Level Grind: Averted. He did some Level Grinding while waiting for Hero to show up because he had nothing better to do. One has to wonder how though, since he's rooted in place.
    Galgarion: I can't actually move from this spot.

    Dr. Blight
Voiced by: Tessa Auberjonois

Dr. Barbara "Babs" Blight is an eco-terrorist scientist from Captain Planet and the Planeteers who helps Lord Boxman pollute the plaza.

Hero Level: Unknown

  • Character Overlap: She, along with Kwame and Captain Planet, are from Captain Planet and the Planeteers.
  • Fangs Are Evil: One key difference between Dr. Blight design in this show and her original design is that she sports a pair of sharp teeth.
  • Missing Steps Plan: She convinced Lord Boxman that it is scientifically proven that he will get more money if he pollutes more, but she never explained to him why. Of course, this is because she only wants to pollute to destroy the world and most likely doesn't care about Boxman's business.
  • Non-Standard Character Design: Her bodysuit employs more traditional shading, similar to her home series.
  • Stupid Evil: When she mentions how the pollution she and Boxman will emit would wipe out all life on Earth, Boxman interjects, saying that it would wipe them out too. She doesn't seem to care in the slightest, and Boxman goes along because he thinks it'll give him a shot at wooing her.
  • The Vamp: She uses her looks to her advantage when negotiating with Boxman, who's practically putty in her hands.

    Dr. Weak Point 
A villain referenced by Carol in a flashback about her starting days as a P.O.I.N.T. member.

Hero Level: Unknown

  • The Ghost: We don't see him, just a robot he sicked on P.O.I.N.T. headquarters.
  • Meaningful Name: Where to hit and defeat this mad doctor's creations is rather obvious.

    Big Bull Demon

Voiced by: Michael Leon Wooley

A cyborg bull villain.

Hero Level: -5

  • A Load of Bull: He resembles a minotaur.
  • Brain in a Jar: His brain is on display on his head.
  • Butt-Monkey: Boxman treated him like this in "Villains' Night Out", by taking away his complementary T-shirt, interrupting his karaoke song, and taking his turn to blow something up.
  • Cyborg: He's part bull, part robot.
  • Horns of Villainy: He has three horns sticking out of his head.
  • Noodle Incident: He ends up attacking the Plaza in Boxman's absence during the summer for some reason.
  • This Is a Drill: He has a drill as his right hand.
