- Eyepatch of Power: He wears one as part of his outfit.
- Eye Scream: He balks when Mordecai and Rigby threaten to blind him with a laser pointer.
- The Hedonist: He relishes in a world where no rules apply, allowing for him to not only do whatever he wants, but also for anyone from any time period to join the party.
- Jerkass: He's cool at first, but then he distracts and punches Rigby, then steals Mordecai's wallet for no reason, and then tries to kill them when the duo warn him about the Unicorns, interpreting that as them telling him what to do.
- Life of the Party: Exaggerated, with him leading an entire world where no rules of any kind exist and allow for many entities to "join the party" and do whatever they want.
- Loophole Abuse: Mordecai and Rigby beat him by abusing the rule that there are no rules against having rules.
- No Name Given: His name is never revealed and is credited as "Mystery Guy" in the credits.

- Paradox Person: He wants to break every rule there is, including the laws of reality.
- Perma-Stubble: Always seen unshaven in his appearances.
- The Pig-Pen: There's no rule telling him he has to shower.
- Puff of Logic: How he's defeated. Mordecai accuses him of having one rule: that there are no rules. He confirms that there isn't such a rule, in turn allowing for Mordecai and Rigby to reapply them and make him and his enemies disappear for violating them.
- Reality Warper: In the No Rules World, he can bend natural laws like gravity to his whim and think up whatever he wants. Upon being being resurrected in "Exit 9B", he can now do this outside the No Rules World, as shown when he makes Skips' armored fists explode by dumping soda on them.
- Rollerblade Good: He wears and gets around on rollerskates.
- Rummage Sale Reject: He wears a mullet, a gold earring, an eyepatch, roller skates, black jeans, a suit jacket, and a pleated dress shirt with a red bow tie; there's no rules saying he can't dress like crap.
- The Slacker: A given for a guy who lives in a place where rules don't exist.
- Squishy Wizard: Despite his reality manipulating powers, he's still easily defeated after Mordecai and Rigby thin out his army of rule breakers, tackle him, and make him lead them out of the No Rules World by threatening to blind him with a laser pointer.
- Temporal Paradox: In his dimension, anyone can enter, including their future and past selves since the laws of reality no longer apply.
- Weaker in the Real World: Seemingly doesn't do much outside of his own personal dimension. No longer the case by "Exit 9B."

It's safe to say Klorgbane isn't meant to be likeable in any way.

- Red and Black and Evil All Over: Decked out in a red and black cape.

A colossal bear who was "evil to the core." It lived in the (now abandoned) Park Zoo and is rumored to still be there.- Ambiguously Evil: Supposedly, it attacked and killed its trainer out of nowhere, but it's unclear whether that's actually what happened or just an urban legend. It attacks Mordecai, Rigby, Margaret and Eileen when they enter its enclosure, but it's unclear if that was out of maliciousness or if it viewed them as intruders on its territory.

When they want more steaks, they would set up a meeting to exchange more Amadeus dollars and then ambush them. Their whole plan is dependent on the park worker's desire for steaks and apparently they didn't bother to take in account that if they use these counterfeit coupons they would get arrested and won't have the chance to meet them. Rigby lampshades it:Rigby: Dude, that's really weird.
Capicola Gang Leader: Well it worked didn't it? - Even Evil Has Standards: When Margaret runs out crying after breaking up with Mordecai to attend her dream college, everybody, including the Capicola gang, ceasefire to allow her leave the restaurant.

- Diabolical Mastermind: He's powerful and influential enough to be able to take over the park.
- Even Evil Has Loved Ones: As nasty of a villain he is, GBF Jr. loves his dad, enough to summon a portal from the Underworld to bring him back and take revenge.

Promise Pie
Voiced by: J.G. Quintel
Debuted in: "Pie Contest"
A talking pie who offers to help Mordecai and Rigby judge the pie contest.- Brutal Honesty: Its Achilles' Heel is Mordecai and Rigby telling the contestants he ate what they really think of their pies, which causes them to be thrown out of Promise Pie and Promise Pie to shrink.
- Deal with the Devil: Unable to tell all the pie contestants what they think of their pies, with some of their pies tasting really bad, Mordecai and Rigby accept its offer to help them judge the contest.
- Diabolus ex Nihilo: It's not clear at all where Promise Pie came from. He just suddenly appears in a trash can and offers to help Mordecai and Rigby with their dilemma.
- Exact Words: Tells Mordecai and Rigby he'll help by "lowering the competition", which he does so by eating everyone he can.
Quillgin
Voiced By: Thomas Haden Church
Debuted In: Season 4, "The Christmas Special"
- Apple of Discord: Quillgin created an empty box that when opened will give whoever opens it what they desire the most. However, the key component used in making the box was Black Magic, which brought out the worst in people and made them fight over it. It was because of this that Santa ordered the box to be locked away and all research pertaining to it destroyed, kickstarting Quillgin's plan to retrieve his creation and use it to destroy Christmas as revenge.
- Big Bad: Of "The Christmas Special."
- Dramatically Missing the Point: He accuses Santa of ruining his life's work out of fear that the box would render him obsolete, with Quillgin apparently incapable of comprehending the fact that it was actually because his creation was too dangerous as Santa tries to point out to him.Quillgin: It didn't have to end this way, but you ruined my dream! If we made a box for everyone, then no one would be fighting over them! Did you ever think of that!? Ha! I bet you did. If everyone had everything they wanted, then why would they need Santa?Santa: It's not like that, Quillgin!Quillgin: Enough! You ruined my life's work, now I'm gonna ruin yours.
- Family-Friendly Firearms: Averted. He carries a real-life handgun that he uses to shoot Santa (who fortunately had a bulletproof vest on at the time) and threaten the park crew with, and has a hand grenade that he uses to try and blow them up with when he loses his gun.
- The Grinch: Quite possibly one of the most evil and dangerous examples of this trope. Not only does he want to destroy Christmas, he plans to kill anyone who celebrates the holiday simply because Santa rightfully rejected his idea for a gift.
- Lean and Mean: He has a rather lanky appearance, something Rigby lampshades when he thought that Quillgin would be one of those stereotypically short elves.
- A Molten Date with Death: His fate at the end of the episode, burning up in the same lava pit that the box is thrown into.
- Our Elves Are Different: In keeping with the special's numerous The Lord of the Rings references, he's much more of a High-Fantasy Elf, being fairly tall, lanky and gaunt, rather than the traditional Chirstmas elf look.
- Satanic Archetype: Once the brightest among Santa's elves, Santa rejecting his box led Quillgin to go rogue and devote himself to destroying Christmas.

Debuted in: "Firework Run"
The owner of the "South of the Line Chile Rellenos" and an underground fireworks dealer.- Beard of Evil: Has a goatee and runs an illegal drug- er... gunpowder operation.
- The Cartel: His whole "Chile Rellenos" operation, which involves him having gunpowder illegally put in the Chile Rellenos to up their spiciness, is very reminiscent of a Mexican drug cartel.
- Family-Friendly Firearms: Played With. He wields what's obviously an AK-47, but loads it up with a firework rather than ammo.
- I Can't Believe It's Not Heroin!: Him filling his Chile Rellenos with gunpowder to increase their spiciness is treated like an illegal drug operation, with it even being mentioned as illegal by the FDA.

- The Dreaded: These geese are so terrifying that even Skips, who has no problems dealing with any dangerous situation, doesn't want to go near them.
- Elite Four: There's four of them and each is highly territorial and dangerous.

- Evil Is Petty: They ruin Mordecai, Rigby, and Pop's sandwich by knocking the sandwich to the ground, kicking dust on it, throwing it in a trash can, beating up the trash can, and rolled that trash can towards Mordecai, Rigby, and Pops. After they temperory beat the baby ducks, they start to destroy everything Mordecai and Rigby cares about, and the first thing they destroy is their standard-defintion TV by blowing it up with missiles.Goose: Fools! The game of "Duck, Duck, Goose" will never end. There will be future lakes... future sandwiches to ruin...

- Feather Fingers: Similar to Mordecai, the feathers on the end of their wings basically act as hands for them.
- Fusion Dance: Can combine into a giant Robeast.

- Hostile Terraforming: Their pooping everywhere turns out to really be a way of terraforming the land to suit their kind.
- Kick the Dog: When Pops tries to tell them to leave, they shove Pops around while they laugh as they make Pops cry. Pops locks himself inside his room crying after that moment.
- Knight of Cerebus: Played much more seriously than most previous villains the park crew has faced, to the point where even Skips would rather stay away from them.
- Macross Missile Massacre: "Scramble Missiles!"
- Multi-Armed and Dangerous: Has a robotic arm in their chest that can electrocute.
- Psycho Rangers: To the baby ducks.

- Would Hurt a Child: None of then bat an eye to potentially killing the Baby Ducks.

Frank Jones
Voiced by: John Cygan
Debuted in: Season 4, "Trailer Trashed"
A health inspector who seeks to condemn Muscle Man's trailer so he can take it for himself.
- Kick the Dog: Played straight initially as Frank not only threatens to send Muscle Man's trailer to the dump and get it scrapped, but when he gives him and his friends a whole day to spruce the trailer, Franks starts to destroy parts of Muscle Man's trailer, from the windows to his door. Subverted, however, as Muscle Man eventually stands up to Frank by decking him in the face.
- Sore Loser: Frank was the runner-up in the hotdog eating contest Muscle Man won his trailer from. He accuses Muscle Man of cheating back then by mushing his hot dogs together with water and that the trailer should've been his, only for Muscle Man to retort that it was totally a fair move and that the Japanese do it all the time.

- Enemy Mime: Gets turned into a mime when being sent to street jail.
- Greed: He steals Mordecai and Rigby's songs because he wants all the money from their act all for himself.
- Hate Sink: Silver Dude is one of the show's villains who had absolutely no redeeming qualities. He shamelessly steals other peoples' songs (primarily Mordecai and Rigby), remixes them and does it along with a basic ball trick. To make it worse, Silver Dude claims that Mordecai and Rigby are the ones stealing his act. In the challenge, Silver Dude continues to remix Mordecai and Rigby's songs with his boombox until they destroy it. Silver Dude proves himself to be a horrible rapper with no musical talent of his own, but instead of accepting his loss, he tries to take the money for himself. Why did he do all these terrible things? Simply because he was a greedy scumbag who had no qualms stealing the talents of others to get money.
- Jerkass: He copies other peoples' acts, while claiming that he's not ripping them off. And he doesn't care at all.
- Laser-Guided Karma: When he gets angry and tries to take the money during a street performing battle, he gets sent to Street Jail.

- You're Nothing Without Your Phlebotinum: He uses his boombox to copy their act; but when his boombox gets destroyed, he tries to rap on his own only to fail miserably.
Bert Coleman
Voiced by Troy Baker
Debuted in: Season 5, "Expert or Liar"
Are you an expert...Or LIAR?!?
The eccentric and mean-spirited host of "Expert Or Liar", a gameshow that makes people answer certain questions or be humiliated on national television.
- Hate Sink: Even by this series' standards, he's so in-your-face odious you'll feel like cheering when Rigby punches him out.
- Hypocrite: He loves exposing his contestants as "liars", while disguising himself and tricking them onto his show in a very dishonest way.
- Jerkass: Coleman gets his thrills from humiliating people with questions very few people would know and seems to actively want them to fail at his contests.
- Inexplicably Awesome: He seems like a normal man at first, but then he shows the ability to warp people to other dimensions based on the subject of his trivia. Given the presence of beings with similar powers, he might be just another otherworldly entity.
- Jerkass Has a Point: He seeks out people who claim to be "experts" and tells them how wrong they are if they don't live up to their claims. Though he's just a huge jerk about it and humiliates them on worldwide television for no other reason just to see them embarrassed.
- Master of Disguise: He approaches contestants disguised as random people with lifelike costumes. Rigby spends a lot of time trying to root him out. Then again, he might just have the budget for that kind of disguise.
- No Indoor Voice: Being a gameshow host, he usually proclaims things loud and obnoxiously.
- Reality Warper: When Rigby approaches him for a rematch, Bert sends them to a video-game based dimension where Rigby must answer each question to overcome obstacles. It's not clear if Coleman actually did this or it's just a metaphorical image, but given the nature of this show, it wouldn't be surprising.
- Slasher Smile: He has an almost constant one.
- Unsportsmanlike Gloating: Coleman is not a gracious host. The reason Rigby wants a rematch is because Bert was just that much of a dick to him for getting a question wrong.Flower expert!? More like A BIG DUMB LIAR NO-ONE WANTS TO HANG AROUND WITH!
- Villainy-Free Villain: He isn't really evil, just a particularly rude game-show host, but he's such a smug, insufferable jackass you're still rooting for Rigby to take him down.
- The Wonka: An eccentric, in-your-face TV personality who apparently has reality-bending powers.

The Internet (Streaming)
Voiced by Roger Craig Smith, Keith David
Debuted in: Season 6, "Format Wars II"
A giant and immensely powerful AI that embodies the internet. It seeks to obliterate all other video platforms to leave itself as the unchallenged format.
- Achilles' Heel: The Internet's first form is a data tower. Once it's destroyed, Internet loses its connection and powers down.
- A.I. Is a Crapshoot: It's a cold and unfeeling entity that solely desires domination over everything online.
- Anthropomorphic Personification: Of the internet, obviously, and more specifically, streaming services. Like the Guardians of Obsolete Formats and Disc family, it's a robotic humanoid with format based powers.
- Arc Villain: It appears any time the Format Wars are involved.
- The Assimilator: Its goal is to make everyone adopt streaming services and to eradicate older formats.
- Bastard Understudy: Seemingly loyally serving DVD. Then it reveals that its goal is the neutralization of all obsolete formats, which includes DVD.
- Big Bad Ensemble: It fights the heroes alongside Anti-Pops during the last season, but it's mainly out for itself.
- Came Back Strong: After its original body is destroyed, it's CPU eventually constructs a massive new body made of Hard Light energy and powerful enough to fight the Duck Mecha, the Guardian Of Lolliland, Blu ray, and DVD all at once.
- Card-Carrying Villain: It is coldly apathetic to others and loudly expresses defeating other formats.
- Climax Boss: Streaming is the last villain fought by the crew alongside Anti-Pops,and is destroyed in the second to last episode, leaving only Pops and Anti-Pops standing.
- Cyber Cyclops: Its head is a Wi-Fi router with several red lights for facial features, the last one being huge and piercing.
- Devour the Dragon: Near the end of the battle against Anti-Pops, the Internet asks all of its minions to join it so that their powers can grow further.
- For the Evulz: Its first line is "Neutralize obsolete formats, loooool."
- Generic Doomsday Villain: The Internet has hardly any personality beyond seeking the destruction of all other video formats. Befitting as it's clearly meant to be an unfeeling machine.
- Hand Blast: Red energy blasts are a basic attack.
- Hero Killer:
- Vaporizes Archie the Laser Disc Guardian in front of his son.
- It proceeds to kill off Reel-to-Reel and Black & White on Planet Nielsen.
- Humongous Mecha: Its body is composed of computer hardware, with its limbs somehow held in place by an invisible force, and it's certainly one of the park crew's more powerful foes.
- The Juggernaut: Even before its first defeat, it was impossible to take down until Mordecai figures out the signal tower is its weakness. DVD flat out calls it unstoppable, and the next time it reappears, it has taken over an entire planet. The upgraded form is even more powerful takes the combined power of everyone to destroy it.
- Killed Off for Real: The Disc siblings are eventually able to destroy its energy form, and what's left of the monster is erased by Anti-Pops. While the internet obviously still functions, its physical form is most likely no more.
- Kryptonite Factor: Its dependence on internet connectivity is not shared by other formats.
- Lack of Empathy: When DVD asks for it to have a heart, it responds, "404: not found."
- Logical Weakness: It relies on internet connections to function. Taking down a local data tower stops it the first time, and being struck a couple times on Planet Nielsen causes it to have to buffer.
- New Media Are Evil: The current and latest in broadcasting and technology, represented as crushing the more heroic physical and obsolete formats in the name of dominance.
- Take That!: Many insults hurled towards the Internet are themed around its disadvantages and problems, such as poor digital compression, buffering, taking shows away when it goes down, and oversaturation in the market.
- There Is No Kill Like Over Kill: It gets shredded like cheese by Gareth's Keytar attack, then sent flying by the Disc siblings' soundwave blast. When he lands, the Guardian of Lolliland elbow drops him for good measure. Then his ravaged body is erased along with the rest of the planet by Anti-Pops. It's safe to say he won't be troubling the crew anymore.
- Villain Team-Up:
- It gets recruited by DVD to launch an attack against the Obsolete Formats and the Disk Masters.
- It joins the final battle with Anti-Pops against the heroes.
- We Will Meet Again: Its router head pops up at the end of "Format Wars II", swearing that streaming will conquer all. It makes good on its promise by "The Seer."

An award winning reporter and robot from the future, yes, yes I am. I was sent to infiltrate and destroy Local news! In my time, it is the one blemish on our utopian society!
Margaret's rival in the Channel 5 News biz, who is another reporter seemingly out to sabotage Margaret's segment to help her own career. Turns out something way bigger is going on, as Jackie is an android from the future sent to discredit tv news broadcasting as an outdated information source.
- Affably Evil: Being here solely for one mission, she doesn't have it in for Margaret as you'd think and even tries to avoid a fight by reasoning with her.

- Dark Action Girl: A formidable and cunning foe despite being introduced as your standard workplace rival.
- Determinator: She stops at nothing to take down TV News, and given what she's homaging, could be considered a literal example.
- Expy: Of both the T-1000 and T-X.
- Fights Like a Normal: Despite being a liquid metal machine, Jackie barely displays any powers besides regeneration and super-strength, needing only her agility and combat skills to complete her objective.
- Implacable Woman: Getting shot point blank with a Missile will not stop this woman. Nor will an exploding van, apparently.

Randall Ross
Voiced by Jason Mantzoukas
Debuted in: Regular Show: The Movie
The main antagonist of the The Movie, he was Mordecai and Rigby's old science teacher (who likewise coached vollyball on the side) who, in the future, now controls the Timenado and intends to wipe out all of existence.
- Alliterative Name: Randall Ross.
- And I Must Scream:Suffers this fate thanks to his own technology. After being decapitated, his time-collar resets to when his head expires, forcing him to die over and over, in an infinite loop. Even worse, he's swept away as a helpless head into the timenado, doomed to sail through the timestream while unable to ever die. Thankfully, this is presumably averted when the Bad Future is aborted.
- Big Bad: Of The Movie.
- Combat Pragmatist: Utilizes his teleportation in combat.
- Disproportionate Retribution: Wants to destroy Earth and the whole timeline simply to get back at Rigby for costing him the school's championship volleyball game. To the point he even tries to kill Mordecai despite Future Mordecai working for him. Ironically when Rigby apologizes for his actions, Ross calls the whole vendetta off.
- Evil Laugh: A Running Gag. He constantly tries to do these but it always ends up with him coughing.
- Expy: Quite possibly of Syndrome, since Ross is also an unrecognized genius who became a high-tech supervillain over rage at the protagonist for a perceived slight, has killed many heroes, and is causing destruction on a massive scale for the sake of his ego. He also has a childish sense of humor despite being played mostly serious, has grown his hair into a wild spike, and in the end is undone by a part of his own outfit. Coincidentally, both their VAs have the same first name.
- Freudian Excuse: He was devastated by the loss of the championship, which meant that all of his efforts amounted to nothing. This is an Ironic Echo to what Mordecai faces in the movie.
- Hero Killer: Responsible for killing most of the park crew in the future as well as Future!Mordecai when he took bomb meant for his present self.
- Hoist by His Own Petard: His reset necklace is sliced in half by Rigby causing him to consonantly relive his decapitation over and over.
- Karmic Death: Two-fold! Ross' whole deal is screwing with time for his evil, selfish whims. When he's decapitated, his time collar forces him to repeatedly die in a constant temporal loop. Also, he's driven by his irrational need for revenge on Rigby. Therefore it's fitting(and probably merciful) that future Ross is erased from existence when his past self decides to forgive his once hated student.
- Large Ham: That being said, he still has a very loud and exaggerated personality.
- Laser-Guided Karma: Randall Ross prides himself on controlling time for his own selfish deeds and has no regard for the damage he inflicts on reality. This gets him back in a very big way when he loses his head, and the collar he used to cheat death revives him endlessly as he's sucked into the timestream. Now he's at the mercy of the force he harnessed, with no control over what happens.
- Last-Name Basis: Everyone calls him by his last name.
- Off with His Head!: Gets decapitated by Rigby in the final battle.
- Omnicidal Maniac: Implied. His goal was to destroy all of time which likely would have killed everyone or trapped them in a single moment of time.
- Portal to the Past: Has gained control of the time stream and uses it to destroy everything with the Timenado. During the final battle, he has the time stream wrapped around his space station, and a hallway is littered with time portals of Mordecai and Rigby's history together.
- Reset Button: Has a necklace which revives him one minute into the past if he takes a fatal blow. It doesn't work if it's sliced in half.
- Sore Loser: He lost a volleyball game to Rigby. His response to the loss is deciding to crash the timeline, taking Earth along with it.
- Teleport Spam: Loves to teleport during fights to gain advantage over his opponents.
- Time Crash: His ultimate goal is to destroy all of time.
- Villain: Exit, Stage Left: Even through Past Rigby apologizes to him for the game and he calls off his revenge, the principal still has him arrested for bringing plutonium into the school.

- Cain and Abel: He's the Cain to Gary's Abel.
- Cold Ham: While his dialogue is rather emotional, his tone is extremely subdued.

- Graceful Loser: After Gary bests him with discord music, he calmly accepts his defeat while being launched into the sun.

Voiced by Troy Baker
Debuted in: Season 7, "The Button"

Anti-Pops (Malum Kranus)
Voiced by: Robert Englund
Debuted in: Season 8, "The Dream Warrior"
The final Big Bad of the show, a mysterious individual who bears a striking resemblance to Pops who resides in space. It is revealed that they are twin brothers with Anti-Pops being the evil one.
- Alas, Poor Villain: Pops ends their duel not by fighting him, but by expressing brotherly love to Anti-Pops through a hug, the positive feelings weakening him enough for Pops to fly them both into a nearby star. At first Anti-Pops reacts with anger and fear, but as the end draws near, Anti-Pops expresses his regrets for the evil he's done. Pops tells him that while he can't undo his actions, he can at least try his best to make up for them. Anti-Pops finally returns Pops's hug, and they die in peace.
- Arch-Enemy: Wants Pops dead for some unknown reason and wants to kill him. It turns out that Pops is destined to be the one who can defeat him.
- Arson, Murder, and Jaywalking: A scourge of the stars who's not above erasing anyone who crosses his path or displeases him... and likewise likes to leave one star reviews for restaurants he's never even visited.

- Bad Is Good and Good Is Bad: His happiness feels like sadness to Pops' telepathy.
- Beard of Evil: Being literally Made of Evil and has a long beard compared to Pops' mustache.
- Big Bad: Of Season 8. Interestingly he's more of a recurring constant threat than the usual one offs that comprise most of the other villains of the show.
- Borrowed Catchphrase: "Bad Show".
- Cain and Abel: He's the Cain to Pops's Abel for they are brothers.
- Die, Chair, Die!: He usually takes his anger out on the surroundings when he doesn't get what he wants. Deconstructed, as he does this up to before the final battle and ends up destroying his ship's engines, preventing him from reaching the planet for a while and giving the heroes ample time to prepare.
- The Dreaded: Feared all over the universe, including Rawls!
- Establishing Character Moment: Twice. His first cameo appearance has him giving a bad Yelp review even though he'd never eaten at the restaurant in question. His first full appearance has him murdering a store clerk for holding up his ship.
- Even Evil Can Be Loved: Double Subverted. On the first attempt, Pops tried to talk him out of committing evil deeds, which did not succeed, in which Anti-Pops nearly erased his brother. The second final attempt in the final episode was successful: Not only was the universe restored to its rightful balance, but Pops was also able to reach his brother's heart in the process as both were hurled into a nearby star.
- Evil Is Petty: Erased a cashier out of existence simply for taking too long. Also, he gives one-star reviews out for fun.
- Evil Overlord: Has a massive fleet and starship at his command.
- Evil Twin: To Pops. He's every bit as cruel and evil as Pops is sweet and kind.
- Final Boss: He's the last enemy the group faces in the series.
- Good Hurts Evil: Pops hugging him in genuine brotherly love and kindness weakens him and leaves him helpless as Pops allows them both to fall into a star.
- Greater-Scope Villain: He manipulated the events throughout the series, and is the most powerful of all the villains in the show.
- Heel Realization: Before meeting his end, he regrets the one-star reviews and wished he could take it all back. Pops even cheered him up by stating he could try.
- Hero Killer: He kills Pops' teacher, Earl and nearly all the park crew and their allies in the finale. All of them got better.
- Hurl It into the Sun: Pops kills him by weakening him with a hug and restraining him while they both fly into a star.
- I Lied: In the Final Battle, he tells Pops that all one of them has to do is knock the other one down to win. When Pops successfully (by pinning him under a ship), Anti-Pops simply calls his mooks to attack him and keeps going anyway. When Pops calls him on it, he points out he's not exactly the most trustworthy person.
- It Amused Me: He lets Rawls commit to his a thousand push-ups in two minutes because he was interested to see if he could do it
- Jerkass: Not only is he a sociopath, but he purposely gives bad reviews for fun.
- Killed Off for Real: Dies when Pops restrains him with a hug and allows the two of them to fall into a star.
- Made of Evil: According to The Ice Tape, he is pretty much an embodiment of evil to counteract Pops being Made of Good. The people of Loliland pretty much confirm it.
- Mutual Kill: Every single fight the two of them have fought, he and Pops end their battle in a universe destroying tie, after which they're both reincarnated to do it all over again. Their Final Battle ends with both dying as well, but in a very different way.

- Obviously Evil: A floating black and white Humanoid Abomination (who looks like Pops) decked in a cape and Beard of Evil.

- One-Winged Angel: During his final fight with Pops, Pops manages to knock him off the high platform they're fighting on... only for him to rise back up as a giant, more demonic form.
- Painting the Medium: His power to erase anything from existence is portrayed as him essentially undoing the process of animation. He first renders an object to post-it note sketches, then its storyboard outline, and finally a blank white space where it used to be.
- Physical God: Is a god-like embodiment of evil so powerful he's capable of destroying the universe. Pops is the only being strong enough to match him, and their fights always ended in multiverse breaking ties.
- Power of the Void: Whenever he erases something or someone, all that remains is a white void in the shape of what was once there.
- Psychopathic Manchild: Compared to Pops who is an innocent manchild that enjoys catching butterflies and joyfully having fun with his friends. Malum enjoys destroying things for his own amusement with childlike glee and throws tantrums whenever things don't go his way.
- Red Baron: Known to many in space as "He who will erase us".
- Redemption Equals Death: During his last seconds of life, he ends up regretting his one-star reviews and genuinely returns his brother's hug.
- Restart the World: He wants to erase the entire universe because he considers it a huge disappointment.
- Story-Breaker Power: Anti-Pops can erase anything he wants from existence, which extends to entire buildings and space stations. At his strongest, he could erase the entire universe. By all means, he should be able to wipe out the crew in seconds. Fortunately, he's quite lazy and too preoccupied with giving 1 star restaurant reviews to actively seek out the heroes, which gives them ample time to prepare and fight him.
- Together in Death: He and his brother Pops die while hugging each other as they fall into a star.
- Walking Spoiler: Due to both who he looks like and his first major appearance being a massive Wham Episode that changes the direction of the season.
