OK K.O.! Let's Be Heroes/Characters/Boxmore

Lord Boxman
Voiced by: Jim Cummings, Parker Simmons ("Legends of Mr. Gar")

The owner of Boxmore, who menaces Lakewood Plaza.

Hero Level: -10
 * Arms Dealer: His business sells Killer Robots to other supervillains.
 * Artificial Limbs: His entire left hand is a chicken foot.
 * Bi the Way: Well, kinda. While obviously not explicitly stated in show, Ian JQ that Lord Boxman is pansexual, and he's shown attraction to both males (Professor Venomous for most of the series) and females (Dr. Blight in "The Power is Yours.")
 * Big Bad: Due to being the owner of Boxmore, his rivalry with Lakewood Plaza, and his robots frequently menacing the strip mall, he fits the position of main antagonist.
 * Big Beautiful Man: He's very plump, and very self-conscious about it, but his Shirtless Scene in “We’re Captured” — during which Professor Venomous can clearly be shown checking him out — shows that Boxman has a surprising amount of muscle under all that blubber. Even without said muscles, though, Venomous (and quite a few fans) certainly finds Boxman attractive.
 * Corrupt Corporate Executive: He's the owner of Box More and sends robots to destroy Lakewood Plaza Turbo to stop friendship from hurting his sales.
 * Cuddle Bug: For someone who claims to hate friendship as much as he does, Boxman is not at all averse to physical displays of affection with Professor Venomous, often hugging him, holding his hand, or otherwise just wanting to be near him.
 * Cute Little Fangs: One of his fangs sticks out when his mouth is closed.
 * Cyborg: He's mostly human, but with robotic ears, a cybernetic left eye, and metal plating on a fourth of his face.
 * Even Evil Has Standards:
 * In "We're Captured", when K.O. thinks Boxman is going to cook and eat him and his friends, he tells K.O. he's a villain, not a monster.
 * In "The Powers Is Yours!", he questioned Dr. Blight's logic behind polluting the Earth, seeing as how they live on it.
 * When T.K.O. and Shadowy Venomous join forces and begin rampaging and destroying everything for the hell of it, he calls it quits and reassures that he isn't a monster as he doesn't wants to destroy things for the sake of it, this gets him fired by Shadowy Venomous.
 * Evil Genius: He builds all his robots and sends them to destroy Lakewood Plaza Turbo.
 * Fangs Are Evil: Has a mouth full of sharp teeth, one of which sticks out when his mouth is closed.
 * Fat and Skinny: The fat one with Professor Venomous.
 * Fatal Flaw: Boxman's continued inexplicable obsession with attacking the plaza has done him in time and time again since the beginning. It has caused his smartest robot to defect, earned him ridicule amongst the other villains, caused his business to suffer, and, after learning nothing from a close call, ultimately cost him his job. Every now and again we're given a look at the kind of villain Boxman could be if he applied his talent in machinery more.
 * Feeling Oppressed by Their Existence:
 * In "Stop Attacking the Plaza", just seeing K.O., Rad, and Enid hanging out together as friends was enough to make him want to attack them.
 * "Lad and Logic" showed that the very idea of a plaza for heroes being built nearby was treated by Boxman as something absolutely unacceptable. Even when he was told by Mr. Logic that the plaza's existence would actually help his business in the long run (due to more heroes meaning an increase in villains buying his robots), he insisted on destroying it.
 * Has a Type: His apparent attraction to Professor Venomous and Dr. Blight would make it appear he's got a thing for Hot Scientists.
 * High Collar of Doom: His lab coat has a high collar.
 * Mad Scientist: An evil robotics engineer.
 * Meaningful Rename: He was called "Lad Boxman" until sometime after Lakewood Plaza was built.
 * Pragmatic Villainy: He's briefly confused as to why Dr. Blight wants to destroy the world, since they live there. Subverted when he decides to just roll with it.
 * Psychopathic Manchild: He's very immature and very dangerous.
 * Pyrrhic Villainy: His obsession with attacking the plaza cuts into his actual business' productivity so much that his investors almost bail on him over it.
 * Red Oni, Blue Oni: Boxman is more loud and boisterous than the soft-spoken, level-headed Venomous.
 * Red Right Hand: One of his arms is a chicken leg, and a part of his head is mechanical.
 * Robot Master: Has an army of robots that he sells and uses for his own personal use.
 * Truly Single Parent: Boxman and his robots refer to each other in familial terms, though he's not very fatherly toward them.
 * Ugly Guy, Hot Wife: While "Ugly" is pushing it, Boxman is short and chubby with some odd features, yet in season three finale he ends up married to the very handsome Professor Venomous.
 * Villain Protagonist: Strangely, while Boxman is the show's primary villain, the majority of his screentime occurs in Villain Episodes where he is the protagonist.
 * Villainous Friendship: Professor Venomous is the only one of Boxman's fellow villains that he doesn't loathe, and the two quickly develop an Odd Friendship, eventually leading to a merger and marriage.
 * Welcome to Evil Mart: Boxmore in a nutshell.
 * Wicked Stepfather: In season three finale, he marries Professor Venomous, meaning Lord Boxman is K.O.'s stepfather.

Professor Venomous

 * See here.

Minions
Boxman's robotic minions and "children". They're the main product line of Box More, though we mostly see them used by Boxman himself to attack Lakewood Plaza. True to the name, they're deployed in boxes launched out of the factory.
 * Hive Mind: Boxman has described his robots as being teenaged with a hive mind. This gives some explanation on their constant reproduction with intact memories.
 * Killer Robots: They're apparently all designed for combat, and armed to the teeth.
 * Parental Title Characterization: Most of the robots call Boxman "daddy" when they're trying to be nice, or "father" when being serious or apologetic. The exception (besides the ones who can't really speak) is Ernesto, who's treated more like an employee than family, and calls him "Lord Boxman".
 * Psychopathic Manchild: The robots act like spoiled children. They constantly cling to and vie for their father's attention, they throw tantrums and hissy fits when things don't go their way, and their room looks like a playpen.

Ernesto
Voiced by: Chris Niosi

A series of robots that work in the cubicles at Boxmore. Lord Boxman created them to be executive managers of Boxmore.

Hero Level: -5
 * Adorkable: When not on the job, Ernesto is a nervous, sometimes shy dork who fumbles around a lot.
 * Affably Evil: Even while attack the Plaza, Ernesto lacks his siblings condescending attitude toward his opponents. He even holds an honest conversation mid-fight, and thanks Dendy for her helpful advices.
 * Be the Ball: They can roll around in a ball form.
 * Cyber Cyclops: This robot model seems to have one eye.
 * Geek Physiques: He's a major nerd with a spherical body.
 * Leitmotif: When he fights, an Electro Swing tune plays in the background.
 * Nice Guy: He's a friendly, outgoing guy who's always polite and helpful... at least as long as you're not fighting him.
 * Nice Hat: Some Ernestos wear top hats.
 * Only Sane Employee: He's the only Boxmore employee that's not in some way childish, stupid, or obsessive about pleasing their father.
 * Please Keep Your Hat On: In "Let's Watch the Boxmore Show", his hat get knocked off to reveal that his balding. He's quite embarrassed about his thinning hairline. By the time of "Sidekick Scouts", he's covered it up with a spike attachment.
 * Punch-Clock Villain: In stark contrast to the other bots, Ernesto holds no real ill will to others; he's just doing his job, and doesn't seem to really enjoy said job either.
 * Purple Is Powerful: They're purple and the executive managers of Boxmore.
 * Token Good Teammate: Generally speaking, he's the nicest of the bots and isn't really actively malicious, just doing his job.
 * Stout Strength: Despite their round appearance, they're super strong and tough.
 * You Are Number 6: Each Ernesto is identified by number.

Jethro 2.0
Voiced by: Dave Herman

A Jethro overcharged with glorbs, becoming self-aware.
 * Grew Beyond Their Programming: A production glitch results in this Jethro being overcharged with glorbs, causing him to develop sentience and his own personality. With encouragement from K.O., he quickly starts causing all the other Jethros to display self-awareness and drive of their own.
 * Mook–Face Turn: He quickly finds himself empathizing with K.O. and the other plaza heroes more then Boxmore, and soon he's begun to encourage the other Jethros to revolt against Boxman and Venomous and working to undermine them.
 * Mook Promotion: This Jethro is accidentally overcharged with glorbs, causing him to develop self-awareness and an actual personality.
 * Non-Malicious Monster: Whereas most Jethros are this because they're harmless, this Jethro chooses to be this.
 * The Starscream: Played straight, as he quickly begins working to encourage the other Jethros to revolt against and overthrow Boxman, albeit for noble reasons.
 * Token Good Teammate: As of "I Am Jethro", he's become this to Boxmore after gaining sentience; he's a genuinely kind and good person who quickly sets to work trying to liberate his fellow bots and secretly overthrow Boxman.

Raymond
Voiced by: Robbie Daymond

One of Lord Boxman's robot henchmen/children. Very flamboyant and over-dramatic, with a love of sports.

Hero Level: -3
 * Agent Peacock: He has a fancy hairstyle and holds a rose in his teeth, in a manner reminiscent of stereotypical bullfighters and flamenco dancers. In "Project Ray Way" he even tries to start up a fashion business of his own.
 * Action Fashionista: He's a powerful fighter and quite The Dandy in terms of style.
 * Ambiguously Human: His flesh and blood counterpart in "OK AU" has pointy ears yet his ears still have bolts in them almost resembling piercings. This could hint at him being some sort of elf species or similar.
 * Arrogant Kung-Fu Guy: He's very arrogant and prideful of himself to a fault. Unlike his brother and sister, he has the skills to back it up.
 * Berserk Button: Insulting his sports skills is a quick way to get his attention.
 * Cheated Angle: Similar to Phineas, his head is never seen from the front.
 * Creative Sterility: Despite being something of an amateur fashionista, he mainly creates clothing by copying others' designs and churning out mass-produced bootlegs.
 * Custom Uniform: His role-swapped flesh and blood counterpart in "OK AU" wears the blue vest rather than Gar's default uniform crop tops. This very well aligns with how he was a newer robot when he was introduced in the show's main universe similar to K.O. being the newest employee.
 * Delinquent Hair: He's got a pompadour to emphasize his "bad boy" image. Enid even calls him a "pompa-dork" while fighting Enid.
 * Flower Motifs: If Raymond is in the scene, expect a lot of roses to be nearly.
 * Green and Mean: Has a green and yellow color scheme and is one of Lord Boxman's most powerful robots.
 * Jerk Jock: He's a villainous young man with a special fondness for sports.
 * I Know Madden Kombat: Raymond uses sports equipment, which include a penalty box, rollerblades, and a bowling ball. And he managed to defeat K.O., Rad, and Enid easily with them.
 * In Touch with His Feminine Side: Along with being an amateur fashionista, he's quite happy to wear "girly" clothing and colors, and is a bit of a tomgirl in general.
 * Mr. Fanservice: He's a "sporty Casanova" whose muscular build is accentuated by provocative poses and a flamboyant fashion sense (including a very revealing swimsuit in the Beach Episode.) Rad and Drupe have both commented on his good looks a few times.
 * The Narcissist: He is quite vain and obsessed with his good looks.
 * Red Eyes, Take Warning: Has red eyes and is a much more effective villain than any of Boxman's robots thus far.
 * Sinister Schnoz: He's shown in one episode to be self-conscious about the size of his nose.
 * Sissy Villain: He's very flamboyant, overly dramatic and in "Plaza Prom" he even calls himself the "prince of panache".
 * Sliding Scale of Villain Effectiveness: Raymond is more effective than any of Boxman's main villains thus far.
 * Spikes of Villainy: Two big ones on his shoulders. He also has other two in his elbows, but those aren't always visible, as if they were retractable.
 * You Gotta Have Blue Hair: Has a dark green pompadour.

Mikayla
Voiced by: Melissa Fahn

An animalistic robot model.
 * Beware My Stinger Tail: She can use her plug tail to attack enemies like a scorpion sting.
 * Mix-and-Match Critter: Is designed after several different creatures. Rad also likens her appearance to a guitar.
 * Zorro Mask: She finally leaves the box she was sent to the bodega in by making an M on it this style.

Robbie

 * Arm Cannon: It shoots robotic sentient bombs known as Sara.

Sara

 * Cyber Cyclops: Only has one eye.
