The main robot itself. Originally the Avatar Prototype, a weapon created by the Glorft, until captured by the humans and refitted into the M.E.G.A.S. (Mecha Earth Guard Attack System.) It was supposed to be sent two years in the past to provide the edge humanity needed in the war against the Glorft. However, an attack from the aliens sent the mech back to the early 20th century instead, and it stayed there for decades until Coop unearthed it in a Jersey City junkyard. The... extensive modifications he made to Megas serve him well in the ensuing conflicts against the Glorft.
- Do-Anything Robot: And by "do anything robot", we mean "do anything robot". It even has the original Wave-Motion Gun in its chest.
- Empathic Weapon: Megas is not actually sentient, but Coop treats it as if it were a person. Also, Megas' arsenal has activation controls that lampshade the current situation, implying a certain form of communication between the robot and its pilot.
- Fun with Acronyms: Mechanized Earth Guard Attack System
- Giant Scrap Robot: Despite its aesthetic, it's subverted given its origins. Only the cockpit is made from scrap.
- Humongous Mecha: Said to be 80 feet (24 meters) tall.
- More Dakka: If the big guns come out, they don't stop shooting. Up to Eleven with "Super Destructor Mode", although Coop doesn't manage to hit anything with it.
- New Powers as the Plot Demands: It gains new abilities on Coop's whims either as a one off joke or as a set up for the next convenient plot resolution for the episode.
- Primary-Color Champion: It's car/head is red, while the rest of its body is blue with yellow flames.
- Super Robot Genre: New Powers as the Plot Demands? Check. Hyperspace Arsenal? Check. Rule of Cool? It's a "giant robot from the future, with a car for a head."
Harold "Coop" Cooplowski
Coop is MEGAS' current owner. He lives in his mother's basement in Jersey City, and is a fan of video games, Pay-Per-View wrestling, cheesy monster movies, cars, and overeating.
- Achievements in Ignorance: Coop is an amazing mechanic but sometimes even he has no idea what his killer weapons do. There's also the fact that he managed to get the robot working at all despite replacing the control hub with a car.
- Acrofatic: His reflexes are surprisingly good for someone his size.
- Arson, Murder, and Jaywalking: During the final confrontation with every monster he fights, he will typically list the three most terrible things the bad guy did to him. The third one is always the most trivial, like complaining about the antagonist making him jog.
- Attack! Attack! Attack!: Coop's main strategy when fighting often involves him simply beating the ever loving tar out of anything against him, or alternatively the biggest explosion he can find.
- Berserk Button: Played for Laughs. Almost every episode features him going on a "roll" about the evil things the Villain of the Week did and then a personal grievance (often something that was his fault). Played Straight when it comes to messing with food, MEGAS, or wrestling.Coop: Looks like someone needs to watch a little more pay-per-view wrestling!Evil Coop: Everyone knows that stuff is fake!(Beat, Coop looks genuinely hurt.)Coop: Does THIS look fake?!
- Big Beautiful Man: Despite the jokes about Coop's grotesque eating habits and his weight, he's designed with somewhat down to Earth good looks and could be considered ruggedly handsome instead of conventionally handsome. It helps that he's not at all ashamed of his weight and isn't much of a Fat Slob aside from a couple of Gass Hole jokes. He's more well groomed than you'd think for a gamer/grease monkey who lives in his mom's basement.
- Big Eater: In reference to Coop's performance during an eating contest, Jamie says that Coop doesn't get sick, he just gets less hungry. During said eating contest, he ate 179 wieners and drank an entire jar of butter. He even stated he was still hungry and wanted Rocky Road ice cream afterward.
- Big Fun: There's nothing Coop loves more than playing video games and eating grotesque amounts of food.
- Blood Knight: Most prevalent in the Galactic Championship tournament.(completely surrounded by enemies, as a metal cage descends from the ceiling)Coop: Oooooh! Steel cage match! Now we're talkin'.
- Brilliant, but Lazy: Coop's mechanical skills are nothing to laugh at; and he's proven to be quite a problem solver by trying methods nobody else would think to do. Between this and His evil, competent counterpart; one has to wonder what Coop could achieve with his life if he ever applied himself.
- Confusion Fu: Coop's greatest asset is pretty much the fact no one, most of the time not even himself, knows what he's going to do next.
- Destructive Savior: He tends to cause a fair bit of destruction due to using extreme methods to deal with the Monster of the Week.Kiva: (Surprised) Amazing! You defeated the enemy, and you didn't have to destroy a planet to do it.
- Determinator: He'll never give up a fight even when all hope is lost.Coop: You're not giving me a lot of options here. We're gonna blow up if we fight and they're gonna paste us if we don't! (enemy robots surround Megas) Blow up it is!
Evil Coop: You know you don't have a chance.Coop: I don't know nuthin!
- Perhaps nowhere more evident than the time he's fighting a stronger evil alternate reality version of himself.
- Drives Like Crazy: Aside from piloting MEGAS, when he has to retake his driver's test he smashes through cardboard cutouts of a family, runs the car up on two wheels to dodge cones, and ultimately ducks under an oil tanker and turns the car into a convertible.
- Completely averted when it comes to combat driving, however. When trapped on the Glorft mothership and separated from MEGAS's body but not the car, he outmaneuvers the entire ship's forces intentionally using basically the same tricks, and sends a junkyard's worth of Glorft mechs crashing into each other trying to catch him.Coop: Ha-ha-hah! You chumps wouldn't last three seconds on the Jersey turnpike!
- Completely averted when it comes to combat driving, however. When trapped on the Glorft mothership and separated from MEGAS's body but not the car, he outmaneuvers the entire ship's forces intentionally using basically the same tricks, and sends a junkyard's worth of Glorft mechs crashing into each other trying to catch him.
- Fat and Proud: "Chubby? Ladies, this is fat!"
- Genius Ditz: Keep in mind he was able to repair a broken mecha from the future while still upgrading it as time goes by in spite of being who he is. Of course his upgrades don't always work the way he intended them to and sometimes its implied even he isn't entirely sure what some of his modifications are supposed to do.
- Good Is Dumb: But he is capable of Achievements in Ignorance.
- The Hero: He is the main character and the pilot of Megas.
- Hero Insurance: It's lampshaded that he often does more damage than the villain!
- Hot-Blooded: Especially after he gets pissed off.
- Hollywood Tone-Deaf: Weaponized through a custom sound system he installed in MEGAS called "the Jammer".
- Idiot Hero: Most conflicts in the series are caused by his idiocy.Coop: "For SOME reason, everyone keeps calling ME-The Bad Guy! I may not be the best guy...But I sure ain't no bad guy!"
- I Know Mortal Kombat: His expertise at playing video games is what makes him such a great pilot.
- Leitmotif: His battle theme "Short Hair" always accompanies moments when he singlehandedly takes down swarms of enemies.
- Lethal Klutz: Impressively, he does this for both good and bad. The first season finale kicks off because his "modifications" to MEGAS accidentally teleport him into the centre of the Glorft's mothership, but the end of the episode sees him defeat them by accidentally doing the same to his soft drink and and shorting out the ship's power systems.
- Mike Nelson, Destroyer of Worlds: He doesn't MEAN to destroy New Jersey (usually). His fights just tend to level the city most of the time.
- Mundane Utility: Zig-zagged. MEGAS' head is his car, so he uses that for travel, but is prone to using the whole mech for some things like playing around.
- Neet: He's a rare example of one that isn't a shut in computer geek.
- Nice Guy: Stupidity aside, Coop is always willing to walk the extra mile to help his friends.
- Only Known by Their Nickname: He's only ever called Coop, even by his mother. His last name is revealed to be Cooplowskinote , but no first name is given.
- Primary-Color Champion: A red jacket and a pair of jeans.
- Would Hit a Girl: He'd rather not if he can help it but if need be, he won't hold back during a battle.
- Wrestler in All of Us: The core of his "fighting style", absorbed through years of playing video games and watching pay-per-view wrestling. Elbow drops, body slams, clotheslines and rope dives are abundant in almost any fight.
Relatively harmless slacker who regularly sleeps on Coop's couch and camps on MEGAS' backseat, whining. Has occasional milliseconds of bravery and intelligence, but mostly just acts as straight-man to the insanity of his friend's robot piloting adventures.
- Be Careful What You Wish For: In "Junk in the trunk" he complains about the team always getting attacked by "slobbery monsters" and wishes for once they could be attacked by "a giant hot chick". Guess what happens in later episode "Ultra Chicks"?
- Butt-Monkey: He is the prime target of mockery and physical abuse in the show.
- Catch Phrase: Usually drones "Nice..." when he finds amusement in something.
- Cowardly Sidekick: Whenever there is a bad guy around, he will scream in terror while Coop and Kiva work to solve the problem.Jamie: I'm too pretty to die!
- Deadpan Snarker: He tends to be the one commenting about the inanity of their situation or the enemies whenever he's not afraid.
- Harem Seeker: While Coop usually thinks about food, Jamie fantasies about this.
- Sometimes he actually gets one, such as in the second episode but with alien girls.
- Jerkass: Jamie has all of two Pet the Dog moments in the entire series. It is often implied that he brings absolutely nothing to the table in his friendship with Coop, and that he has no skills of his own, yet despite that he is a jerk with a superiority complex who insults his comrades, hits on women, and schemes for his own profit.
- Lovable Coward: Even so, Coop and Kiva consider him a good friend.
- Neet: And apparently has no skills to make up for it.
- Nerd Glasses: A flashback to when he first met Coop shows he used to wear these at one point.
- Only Friend: Confides to Kiva in a moment of weakness that Coop is the only real friend he's got. He feels like he has to come along on the life-risking adventures or he'll be left with nothing. The two begin getting along better after this.
- Power Perversion Potential: First to come up with the idea after Coop shows him Megas.Jamie: "Coop, do you realize what we could do with this thing?"
- Screw This, I'm Outta Here!: Has abandoned his post on occasions where things get tough. Notably in the episode "Ultra Chicks" Jamie is mistaken for Coop by the Space Cadets and recruited to fight a dangerous monster; Jamie keeps up the ruse until the last minute only to run away during the fight.
- Token Evil Teammate: Usually visualizes taking over the world and making his friends his servants and the first thing he thought of if he controlled MEGAS was to rob Fort Knox.
- Took a Level in Badass: In "Rearview Mirror Mirror", after Alternate Reality!Coop decimated the Earth, Alternate Reality!Jamie was left behind and became the leader of the Earth's resistance, and became a pretty capable mech pilot to boot.
Commander Kiva Andru, Earth Coalition Space Force
Time-traveling Ace test pilot from the year 3037 and MEGAS' original pilot. When Earth fell to the Glorft, she and MEGAS were sent back to the 21st century in order to prepare the world for the inevitable conflict. However, upon arriving in 2004, she found that MEGAS had arrived seven decades earlier, spent much of the interval rusting in a Jersey junkyard - and was ultimately salvaged and modified beyond her capability to pilot by Coop. Making the best of an insane situation, she reluctantly assumed the role of Coop's tactical adviser against the Glorft.
- Ace Pilot: She is quite seasoned from battles against Glorft, both for Earth Coalition and the resistance, which made her as the only one with experience and reasons for Coop.
- Action Girl: She can beat anything short of an opponent that requires Megas to defeat.
- The Aloner: She dedicated her whole life to the military and the defense of Earth. She has no family or friends to speak of until she arrived a millennium into the past. She finds one of her ancient ancestors and attempts to bond with an ancestor of hers but is rejected because of the danger she poses from the Glorft's constant assaults on her life.
- Boobs of Steel: You bet!
- Bare Your Midriff: Wears a black tank top that exposes her navel during the Terminate Her episode.
- Breakout Character: Is the character devoted fans and casual observers, alike, first think of when discussing the show. The fact that she, not Coop, nor Jamie, was the Megas XLR character to cameo in Crossover Nexus says a lot about how iconic she is.
- Character Development: A weird case. She begins a hypercompetent fighter who wants nothing more than to go back home and to get Megas back to her time. However, she not only grew to appreciate Coop and Jamie (to a lesser extent); but she came to realize she enjoyed being where she was; and the occasional threat was better than dealing with the daily threat. By the beginning of season 2, Coop seemingly destroyed the Glorft, thus removing any need for Kiva to return home. With no way to get back to her time and nothing else to do, she ultimately became a lazy, do-nothing slacker just like Coop and Jamie.
- Cyborg: To an extent, she sports implants like her cranial plug-port behind her head and hologram projector on her wrist but they are subtle in appearance. Her ALT version, however, become a full-blown version of it with her left-side of her face having mechanical features along with plugging herself with a larger cable behind her skull whenever she's piloting a mech.
- Defrosting Ice Queen: She is mostly an aloof, no-nonsense individual focused in the task at hand, but in time she grows to appreciate some of the guys' activities.
- Fiery Redhead: Red hair and a determined attitude.
- Leitmotif: Kiva has her own battle theme "Lose my high".
- Not So Above It All: Occasionally she will join in fun with Coop and Jamie.
- Only Sane Woman: Most of the time, but she is also prone to getting involved in the antics.
- Simple Staff: Her preferred weapon of choice. Sometimes fashioned from an Improvised Weapon.
- Tomboy: She starts out in the series as a serious and no nonsense Action Girl, but overtime in the series she starts to grow more into a Tomboy when she starts to enjoy some of the things the guys do.
- Wetware CPU: She has a plug-like implant on back skull used for piloting mech, which became incompatible with Megas due to massive modifications made to it by Coop.
- Wrench Wench: Often works on upgrading Megas just as much as Coop does and is usually the one who repairs Megas's more advanced systems after they're broken (typically by Coop). She's also the one who originally modified Megas from the Avatar prototype after it was stolen from the Glorft.
- Arch-Enemy: To Coop
- Badass Baritone: Courtesy of Clancy Brown.
- Big Bad: He is the show's primary source of conflict.
- The Caligula: His bloodthirstiness is equaled only by his incompetence.
- Cthulhumanoid: His entire race is composed of these but as a symbol of importance he is one of the few with a visible mouth and a bipedal structure.
- Defiant to the End: Would rather die fighting than surrender.Gorrath: Surrender? To a human, ha! Destruction it is.Gorrath: The day I hide from an earther is the day the universe implodes!
- No Time to Explain: Quotes this in the finale.Gorrath: Quickly! No time to explain! All units attack formation, form on the earther!Commander: Are you sure sir, shouldn't we destroy him?Gorrath: Don't question my orders! Follow them!
- Red Eyes, Take Warning: He has these, though it's a common trait of his species.
- Revenge Before Reason: On several occasions his obsession with defeating Coop proves to be his undoing.Commander: The Earth is defenseless! We should attack.Gorrath: We can conquer that puny planet any time. I want that monkey now!
- Averted in the Season 2 finale where Gorrath admits "nothing would give him greater pleasure" than killing Coop on the spot but instead he understands the need for them to work together in order to survive.
- Secondary Color Nemesis: Both his entire species and its robots have a shade of green.
- Butt-Monkey: Best seen at the end of "Terminate Her" where Gorrath uses him as an impromptu punching bag whilst he's using a hologram to make himself look like Coop
- Captain Obvious: Does this on occasion to the point of annoying Gorrath.Gorrath: Your penchant for stating the obvious is getting old commander.
- The Dragon: Of Gorrath.
- Deadpan Snarker: Occasionally does this out of Gorrath's earshot.
A parody of Mecha Godzilla. A modified duplicate of MEGAS created by the Glorft and piloted by Warmaster Gorrath.
Between catching a tan on a scrap hill or relaxing in his favourite lawn chair, Goat is the owner and operator of the junkyard in which Coop found MEGAS. Like Jamie, he tries to hit on girls (usually Kiva) and falls just a bit short. He is the same character from MTV's Downtown, sharing the same voice actor and some of the staff of this series.
- Brick Joke: In "Thanksgiving Throwdown" he is seen unsuccessfully trying to flirt with a girl by offering to buy her a churro. Later on in the episode we see that she actually he accepted his offer.
- Casanova Wannabe: Subverted. Most of the time his efforts to impress women (especially Kiva) fail, however he has been successful a few times.
- Character as Himself: While Scot Rienecker was credited as voicing Goat in the first season's end credits, the end credits for the second season instead had Goat listed as playing himself.
- Hidden Depths: He did manage to get an old alien robot working...for a few minutes.
- Ink-Suit Actor: He's based on his actor, Scot Rienecker.
- Lazy Bum: Despite what he claims, he spends most of his time lounging in his junkyard.
- No Smoking: Unlike his appearance in Downtown, he's usually seen with a lollipop in his mouth instead of a cigarette in order to maintain a PG rating.
A group of young superheroes from the planet Sarus. The S-Force protects beings of other galaxies from evil forces. They first suspected Coop to be a bad guy most likely due to Coop's senseless destruction on Earth, only to learn that he wasn't evil, just clumsy. Despite this they became great allies of the heroes.
- Ain't Too Proud to Beg: Targon detests Coop, deeming him a bad influence. Nonetheless, he agrees to Jax's idea of recruiting him for help when the S-Force are captured.
- Animal Mecha: Keeping with their Power Ranger parody, their individual mechs are an eagle, a rhino, a gorilla, a panther and a kangaroo.
- Badass in Distress: The plot of their second appearance; all but Jax are being held captive by Zarrink in "S-Force S.O.S."
- Big Eater: Sloan tends to eat a lot, but he's still nothing in the huge appetite department when compared to Coop. Though thanks to Coop's "training," in S-Force's next appearance Sloan's now as big as Coop. Mac also starts to fatten up at the end of the episode, though is back to normal when the team reappears.
- The Chick: Duchess, the token female of the team.
- Combining Mecha: Known as the Super Ultra Dimensional Magno Extreme Robotoid Powerzorp. Later Coop parodies this with Megas by using their mechs as gauntlets and boots before jamming the leader onto his back in order to power-up Megas.
- Expies: Of the Super Sentai/Power Rangers, Science Ninja Team Gatchaman and Voltron.
- Their Mentor: Targon is an expy of Zordon.
- Intelligible Unintelligible: Jax speaks in a language that only his teammates can understand.
- The Lad-ette: Duchess becomes one thanks to Coop. She becomes a slob and a Gasshole.
- Large Ham: Given who they're based on, they're appropriately pretty boisterous when talking down to villains. Especially Argo.
- Leitmotif: Triumphant fanfare tends to play during their scenes.
- Mis Matched Eyes: One of Jax's eyes is colored red.
- Pink Means Feminine: Duchess, the only female of the team, uses a pink mech and wears a pink battle-suit.
- "Super Sentai" Stance: They wouldn't be a Power Ranger parody without it.
A kid who lives in Jersey City, he often says "Cooool!!!!" when he sees something unusual, such as an alien appearing in the middle of a baseball game. He usually has a Slushie in his hand and delivers the line after taking a long sip.
- The Cameo: Usually appears spectating Coop's wacky hinjinks from afar.
- Unwitting Instigator of Doom: Subverted thanks to the show's cancellation, but he takes a piece of the destroyed R.E.G.I.S. Mark 5 after its destruction as a souvenir.
A friend of Coop. Despite his name, Tiny is considerably larger than Coop. Though like Coop, he is also fond of working with cars.
- Bald of Awesome: He's bald and on Coop's side.
- Doubles as Bald, Black Leader Guy in "The Fat And The Furious" where he leads the humans in their cars against the Glorft.
- Cool Car: His deserves special mention in being able to go toe-to-toe with MEGAS in a car competition.
A video game expert much like Coop, only he isn't as good as him. He also seems to be fond of the Lurps and plays their game series, which is apparently the only game series Coop never played.
- Defeat Equals Friendship: Despite their initial conflict, him and Coop become good friends afterwards.
- Expy: The Lurps are obviously a parody of The Smurfs.
- Pyrrhic Victory: Proves that he's played more video games than Coop but then again, the only game Coop hasn't played is Love those Lurps 7 of all things...
A girl Jamie tried to date, she thought he had a nice car (which was actually Coop's). So Jamie lied to get her to go for a ride which ended up turning into a cat and mouse chase with the Glorft until Coop regained control of MEGAS.
- All Girls Want Bad Boys: She finds Jamie's quirks kinda endearing.
- Cameo: She's the same girl Fruity was flirting with on the subway in Downtown.
- Muggle: Is unaware of who the Glorft are and doesn't want to find out.
One of Coop's friends who is the owner of the impound lot. He seems to know Coop rather well.
- No Hero Discount: Even though Coop urges him to release his car despite his expired license because of a dangerous alien was attacking, he insists that he can't due to the rules.
- Unusually Uninteresting Sight: Is quite lax about the whole giant robot appearances.
Florxin and Tolbit
Crab like aliens who perform transporting and clean-up tasks. Florxin is the tall cynical one and Tolbit is the short clueless one.
- The Cameo: They make a brief appearance in the ending credits of "Junk in the Trunk"
- Heterosexual Life-Partners: They're very close.
- Those Two Guys: They are never seen apart.
Kiva's ancestor from the past, sharing similar appearances. Gorrath tried to kill her, which would directly erase Kiva from history, preventing MEGAS from being sent to the present.
- Bare Your Midriff: Like Kiva in the episode she appears, she wears a purple tank-top that leaves her navel exposed.
- Damsel in Distress: Coop, Kiva, and Jamie have to prevent her from being killed by the Glorft.
Chieftain Ator and the Cryhocks
The chieftain of the Cryhocks i.e. "Space Bigfoots". He is the leader of his tribe of Cryhocks who lived in an ice village. His village was protected by a defector of the Cerulean army but Coop mistook him for the enemy. Ator then explained this to Coop and Coop in return became their guardian... for a short while.
- Defiant to the End: Refused to go down without a fight even though they knew they stood little chance.
- Fur Bikini: After the the ice caps melt turning the planet tropical, some of the female Cryhocks can be seen wearing fur bikinis to adjust to the new climate.
- Noble Savage: They are a relatively peaceful race that are preyed upon by the larger Ceruleans.
- Shell-Shocked Veteran: By the end of the episode, while the other Cryhocks enjoy the new sunny weather, Chief Ator just stands where he is trying to comprehend their Pyrrhic Victory.
Coop's mom who can occasionally be heard yelling at Coop, usually asking what he wants to eat or to pay a bill.
- Disappeared Dad: Coop's father is never heard or mentioned.
- The Voice: She never appears on screen and is only heard.
Coop's annoying bratty cousin. Coop was forced to babysit him in an episode while his mother and Aunt Ester went shopping in the city.
- Bratty Half-Pint: He's a pretty obnoxious kid.
- Tag Along Kid: He goes with the heroes on their adventure against their wishes.
- Unusually Uninteresting Sight: Subverted, Riding in a giant robot wasn't enough to impress him but seeing the Glorft Moonbase was deemed cool by his standards.
Space warriors who came to Earth looking for help, but instead they mistook Jamie for Coop. They needed Coop's assistance in fighting the Kurdock, so Jamie went instead, not knowing what he was getting himself into.
- Sailor Senshi Send-Up: Blatant versions of the Sailor Scouts, since they look like young women in sailor outfits and have Stellar Theme Naming (Galaxia, Comet, Pulsar, and Nova). Only difference is that they turn into giant robots when they transform.
- Transformation Sequence: Nova's is probably the most noticeably in that it parodies the overly long transformation sequences to the point where even her fellow Ultra-Cadets glance over at her, wondering how much longer it was going to take.
The leader of the resistance force in an alternate dimension. He is the hero of that Earth who fights against the evil forces of Coop and his army of robots. He apparently had a relationship with Kiva, but she left with Coop and became evil. Alternate Jamie is a love scorn, battle-hardened man with a knee brace. This version of Jamie is actually the polar opposite of the original Jamie, being very brave and fit.
- Ace Pilot: Has become this over the course of the war.
- Badass Baritone: As opposed to his counterpart's high-pitched whining.
- Cynicism Catalyst: Seeing one's best friend become a sociopathic galactic conqueror and his girlfriend follow him and become a monster is understandably painful and hardened him.
- Deadpan Snarker: He did respond to Coop's question on how he was in such a matter.
- Future Badass: Well, he's sorta one for Jamie, being an older battle-scarred leader of the resistance.
- Good Scars, Evil Scars: Subverted. He has an "evil scar" as we are led to believe he's the bad guy at first until it turns out he's actually the hero.
- Heartbroken Badass: At some point in the alternate dimension, Kiva and Jamie began dating. Then Coop went down the dark path and Kiva followed him. Heartbroken romantically and platonically.
- Nice Job Breaking It, Hero!: Downplayed, but while he had his suspicions regarding our Coop, it did lead to his forces wiped when he had them engage against him and left them open against the real danger.
- Pre-Mortem One-Liner: "Let's see you conquer worlds when you're stuck between dimensions!"note
- Took a Level in Badass: Leader of the resistance force against Alternate Coop
- We Used to Be Friends: He and Evil Coop, just like ours, but apparently something happened to Coop.
- Wham Line: "I am a good guy!" said before The Reveal of Alternate Coop, the true final villain of season 2.
The chairman of the Galactic Combat Championship Federation. He uses Coop to make money in his battle arena, but when Coop refuses to throw a fight for him, Magnanimous uses booby traps and even threatening his friends to make him cooperate.
- Corrupt Corporate Executive: He deliberately rigs the fights to maximise his profit, which is incidentally how he comes into conflict with Coop after he refuses to throw his matches.
- In his second appearance, he suckers Coop into a title-defence challenge on good will as an excuse to sic every fighter in the universe on him at once.
- Chainsaw Good: His first mech. He never gets to use it, though.
- Expy: Of Marvel villain, MODOK.
- Large Ham: He's very hammy.
- Loud of War: Also his first mech, called the "Sonic Abominator".
- Twitchy Eye: In his second appearance, which he blames Coop for.
- Unexplained Recovery: His first appearance ends with him getting knocked into a quantum singularity. He's better by his next appearance... mostly.
A robot who was one of Coop's challengers in "The Return". He often spoke in a mean rhyming tone saying stuff as "T-Bot will pounce you! Trounce you! And utterly denounce you!".
- Determinator: No matter how much he's beaten up he'll just come back for more, even at the end after getting cut in half he's still going, dragging his legless torso along the ground.
- No Celebrities Were Harmed: He's a parody of Mr T.
- Rhymes on a Dime: Although he starts to run out of them by the end.
R.E.G.I.S. Mark 5
An advanced and powerful alien robot gone horribly awry, it was supposed to be dumped into a black hole by a cloaked ship flown by Florxin and Tolbit. Unfortunately, Coop damaged the ship and the R.E.G.I.S landed on Earth.
- Achilles' Heel: Requires solar power to function. Without a constant supply it becomes useless until it is exposed to sun light again.
- Affably Evil: Despite actively trying to eliminate everyone and everything it's mannerisms are rather polite even when threatening others.R.E.G.I.S.: Surrender now, and I will destroy you peacefully.
- Asteroids Monster: Coop's attempts to smash it eventually lead to it splitting into a small army of itself that speak in unison.
- Badass Boast: Loves to do this, and frequently gets beaten to a pulp while in the middle of a monologue.
- The Comically Serious:R.E.G.I.S.: (to fire hydrant) Stand aside, or you will be struck down.(fire hydrant does not respond)R.E.G.I.S.: Die, then. (slices hydrant in half)
- From a Single Cell: Was created with highly advanced nano-technology that can allow him to continually regenerate, grow and multiply with adequate power.
- Fun with Acronyms: The Replicant Engineered for Galactic Infiltration and Sabotage Mark V.
- Leitmotif: Theme of Damnation, which plays almost every time it's on screen.
- Make My Monster Grow: It's introduced as a spider-looking bot roughly the size of a dog, but consumes metallic object to eventually grow bigger than MEGAS.
- Non-Standard Character Design: R.E.G.I.S. looks much more simplified and cartoonish compared to the relatively realistic characters of the series, and wouldn't look out of place in a series like Invader Zim.
- What Happened to the Mouse?: A piece of the robot survives its battle with Megas and gets picked up by the "cool kid". The ending credits shows it revealing signs of life yet it is never seen again.
Short for Reverse-Engineered Collective Robot, it is a robotic, war machine created by Area 50. Its prime programming was to defeat "the enemy", but due to a programming flaw, it considered everything to be that enemy. It was awakened by Coop and fed off of MEGAS' electrical energy to become stronger. After trapping MEGAS in Area 50, R.E.C.R went in search of power for its need to consume vast amounts of energy to operate properly.
- A.I. Is a Crapshoot: It's programming was simply to "destroy the enemy". Unfortunately, its "massive 56-kilobyte processor" didn't have much room for rationalizing who that was.
- Bootstrapped Leitmotif: "Ro-Sham-Bo" is often associated with him as it is prominently featured during his fights.
- Combining Mecha: Inverted, he's a robot that can separate into two tanks, two fighter jets and a UFO respectively. He can also do this to dodge attacks.
- Department of Redundancy Department: "It is unavoidable. All enemies must be destroyed because all enemies are my enemy!"
- Energy Absorption: Which poses problems given that Coop's standard strategy of fighting hand-to-hand allows R.E.C.R to do this to Megas.
- Sealed Evil in a Can: Was first sealed in Area 50 and later in the Grand Canyon by Coop.
- In an alternate time line Evil Coop apparently re-excavated him and this time successfully destroyed him.
A giant space alien that can kill planets who cares for nothing but destruction and misery. He was sealed away long ago, but was released by Coop when he was testing a new game, not knowing it was a containment cartridge.
- Badass Boast: "You will rue the day you met Grrkek the Planet Killer."
- Blood Knight: Craves nothing but destruction. His only regret is that he can only destroy something once.
- Even Bad Men Love Their Mamas: He actually gets offended when Coop insults his mother. (Implying that his mom's house is as big as a planet which indirectly calls her fat as well.)Grrkek: Thanks to your laser feast, I feel good enough to kill a thousand planets! Guess where I'm going to start?Coop: Uh, I don't know, your mom's house? (Grrkek kicks Megas)
- Fate Worse than Death: Coop seals him inside a Lurps video game which irritates him to the point where he begs to be put back into his original prison.
- Feed It with Fire: What Coop accidentally does with a laser barrage. He appears to have been killed, but sheds his skin and comes back three times bigger than before.
- I Love Nuclear Power: Has the ability to generate fusion reactions powerful enough to devastate planets
- Jerk With A Heart Of Jerk:Grrkek: I should thank you for releasing me.Coop: Don't mention it.Grrkek: Instead I shall destroy you.
- Sealed Evil in a Can: Was first trapped inside a cartridge containment prison and then later inside a Lurp videogame by Coop.
One of the S-Force's enemies. He "ends things. People, planets, galaxies". Ender appeared while Coop was fighting the S-Force and wanted to partner with Coop to rule the universe together. But, when Coop insisted he was good and refused Ender's offer, he instead fought with Coop.
- Badass Boast: "I'm Ender. I end things. People, planets, galaxies!"
- Blood Knight: If his name didn't tip you off, he lives for destroying and killing everything he can.
- Card-Carrying Villain: He openly refers to himself as evil, admires Coop after mistaking him for a villain, and seems to enjoy evil for the sake of it.
- Eviler Than Thou: Inverted. When Coop accidentally creates a matter-antimatter rift that threatens to destroy the universe, Ender expresses nothing but pure admiration and even awe as he gets sucked into the rift himself.
- Names to Run From Really Fast: His name definitely qualifies as sinister, given that it emphasizes how he "ends" things.
- Villain Respect: Subverted. Believing Coop to be a villain, he greatly admires his accidental destruction more than anything else. Coop can't stand it.
- We Can Rule Together: Offers Coop this after he (accidentally) defeats the S-Force and is sincerely disappointed when Coop refuses.
Another of the S-Force's enemies and according to Coop, is a "point-headed chump". He captures planet Sarus and tried to throw the S-Force into the Infinity Zone. Just in time, Coop came to their rescue.
- Expy: Of Berg Katse (or "Zoltar", as he is known in the dub), a major enemy of the Science Ninja Team Gatchaman.
- We Will Meet Again: He promises he'll return at the end of his episode.Zarrik: Oh, I'll be back, you inconsequential fools!
An evil space pirate and captain of the pirate battleship Saving Grace. Warlock has a fetish for red hair and he unsurprisingly fell in love with Kiva. He tricked her by promising that he would give her a time drive and attempted to trap by and threatening her with the lives of Coop and Jamie to become his queen.
- Casanova Wannabe: Fancies himself this. Kiva's final complaint when she hijacks Coop's "roll" was having to listen to his "endless, cheesy pickup lines".Warlock: Cheesy!?
- Expy: Of Captain Harlock.
- Exact Words: Lets Coop and Jamie go as promised, but purposely leaves them in a situation that will probably get them killed.Warlock: Come now there's a very good chance they'll survive the impact. Of course they'll be in no shape to fight of the Florkbat if they do.
- Heroes Prefer Redheads: Subverted as his noble appearance is a sham, but his crew groans "redheads, every time!" as he introduces himself to Kiva.
- Hot Wind: Parodied (like everything else), every time we cut to his face there's a wind blowing his hair dramatically complete with sound effects despite the fact that they're in a battleship in the middle of space.
- Ironic Echo: He claims to be the only man to every fight off a hundred lorgnarts, but gets his ship totalled by a swarm of them at the end of the episode. Kiva wastes no time throwing his boast back in his face.
- We Can Rule Together: Hoped to invoke this with Kiva.
An alien plant spore from Saturn. It requires heat to grow and germinate. Taking the disguise of Auggie the Adorable Aardvark (a spoof of Sonic the Hedgehog and Mickey Mouse), it attacked MEGAS because it considered it to be a threat to its germination process, later multiplying and taking the guises of the other Thanksgiving parade balloons.
- Blob Monster: His initial form is a green blob of jelly.
- Phlebotinum Overload: While heat typically makes him stronger, Coop gave him so much that he eventually exploded from being given too much. "Like over cooked popcorn" as Coop described.
- Revenge Before Reason: Gynok goes after MEGAS because Coop unknowingly stepped on him while he was trying to grow and infest the planet. Thus Gynok decides MEGAS is a threat to his survival and decides to neutralize him first. However had Gynok just shrugged it off and continued germinating, Coop likely would not have noticed him until it was too late to do anything.
- Rolling Attack: Uses one in his Auggie form to complete the Sonic homage.
- Terse Talker: Is prone to speaking this way.
- Voluntary Shapeshifting: Gynok can mold its body into any shape or form. But as a catch, he needs to be able to see what he's changing into (i.e. an existing object to serve as the form's blueprint) hence why he took the form of a bunch of cartoon parade balloons to combat MEGAS.
Leader of the selfish and greedy Ceruleans. Because the Ceruleans require water for their coolant systems, they drained their planet's supply of water and became focused on the ice moon nearby.
- Expy: The Ceruleans are parodies of the Decepticons thus making Drallag an expy of Megatron.
- Hoist by His Own Petard: He was tricked by Coop into accidentally destroying his home planet while attempting to destroy him with his flagship's cutter laser.
The head of Prisoner Planet. Klaar reprograms the A.I.'s of dangerous criminal robots for the greater good. He mistook MEGAS for one of these, but the misunderstanding was soon cleared up. Klaar decided to destroy MEGAS anyway due to Coop's interference. Ultimately, the criminals were all released thanks to Coop, who thought the robots were being held as slaves by Klaar.
- Brainwashing for the Greater Good: How he deals with some of the "most dangerous criminals" in the galaxy.
- Offscreen Moment of Awesome: If the end credits scene of one of the robot criminals happily skipping away as it was about to fight Megas is any indication, he somehow repaired the satellite that was used to reprogram the robotic prisoners after Coop destroyed it.
- Wardens Are Evil: What we are led to believe at first but it turns out he was Good All Along
- Well-Intentioned Extremist: He was willing to kill Coop and friends (knowing that they weren't machines) in order ensure they don't influence any of the prisoners ever again.
An intergalactic robotic crimial who speaks in a Spanish accent. Skalgar strives to be the most feared criminal in the universe, but because of his size he is often made fun of. In spite of this, he is incredibly powerful. When he gets word of a universal controller made by Coop, he goes to claim it for his own thinking it will let him control the universe.
- Accidental Misnaming: Coop ends up calling him "school girl" and Jamie later does it deliberately to goad him into firing into his now inverted Deflector Shields.
- Berserk Button: Laughing at or not taking him seriously, especially if it involves mocking his height.
- Deflector Shields: Accidentally gains this on his mech after Coop hits him with the mazer refractor (that he repaired incorrectly).
- Expy: He's based on Unicron from Transformers. Other than the similar design, he's also obsessed with destroying everything in the universe.
- Leitmotif: A few mariachi inspired ones.
- The Napoleon: Loudly proclaims how he should be the most feared criminal in the universe all the while being a midget. Even his mech falls into this being only coming up to Megas's waist in height.
- Red Baron: He tries, thinking up various threatening monikers for himself when introducing himself to Coop and noticeably loses steam as each one is met with a deadpan "never heard of you."
- Underestimating Badassery: Just about everyone who meets him sees him as a joke, even his bounty is only worth 15 credits, despite him being a legitimately dangerous criminal. In his first appearance he single-handedly destroys a Bad-Guy Bar after one robot made fun of him and after facing Megas proper and getting similar ridicule this happens:Coop: Please, this guy is half the size of what I usually have to fight.Jamie: Yeah, little guys are easy to beat up.(Skalgar's mech punches Megas across the city)Jamie: ...I guess we're the little guy.
Giant silicon-based biomechencial worms that are attracted to and feed on pure energy. They were living on a deserted ring-world that was actually an interstellar data storage drive.
- Energy Absorption: Their instinctual drive.
- Reflectionless Useless Eyes: They have eyes but can only see energy. Averted with the Queen worm.
- Silicon-Based Life: Though they are apparently able to reproduce organically.
Planet-Eating Monster: A planet-sized space monster that feeds on radio and television waves. Coop accidentally transmitted a powerful, hi-frequency radio wave into space which caught the monster's attention when Coop tried to "juice" his satellite dish to boost his television reception. After Jamie suggested that the satellite was down, the trio found the monster in space eating TV satellites.
- Big Dumb Object: It's a giant entity from space that causes the conflict in its single episode.
- Feed It a Bomb: Coop blows it up with a nuclear warhead accidentally filled with soda and pop rocks.
- Genius Loci: The creature is basically a giant living planet.
- Proportionately Ponderous Parasites: It's filled with corrosive parasites that Jamie dubs "acid boogers".
- Spikes of Doom: It's mouth is littered with these even though it doesn't chew it's food.
- Swallowed Whole: Subverted. While it typically does this with it's meals, Megas actually gets absorbed through the surface of its skin.
- That's No Moon!: "That thing's a flippin' planet!"
- Womb Level: Coop ends up having to navigate Megas safely out of its stomach. He even mentions the fact that it's similar to "Level 7 of Cavern Crashers."
A giant, fire-breathing monster that has been terrorizing the planet of the Ultra-Cadets. The Ultra-Cadets searched for Coop to ask for his help to save their planet and Jamie foolishly pretending to be Coop to try to get a date went with them by mistake. In their fight, Jamie comically ran from the monster and led it to the foot of a volcano, where it accidentally slipped off before it could finish Jamie.
- Domed Hometown: The Ultra Cadet's home employs a dome as a result of the Kurdock.
- Nice Job Breaking It, Hero!: Jamie's actions only cause the Kurdock to come back from the volcano twice as strong and this time, the Ultra Cadet's home city is without it's shield.
- Twisted Echo Cut: After sending Jamie off to fight the Kurdock the Ultra-Cadets joke that he's probably making the Kurdock beg to be spared. Then we cut to see Jamie begging the Kurdock to spare him. (To no avail)
A redneck-type alien who owned a junk planet. He allowed Coop and his friends to look for a photonic stabilizer only so he could take MEGAS and steal the time drive. He pilots a monstrous robot known as the Franken
- Bitch in Sheep's Clothing: At first seems like a helpful junkhound until he finds out Megas has a timedrive.
- Famous Last Words: "I can fix this..." right before his entire planet gets destroyed.
- Hoist by His Own Petard: Provokes Coop into fighting him and malfunctioning his own robot.
- Mismatched Eyes: One of his eyes is larger than the other.Coop: "Did you notice that guy, Varsin's eyes? They look off in two different directions. Creepy.
- Space Worm: Owns one called Fred.
- Surrender Backfire: When he warns Coop to surrender or be destroyed, Jamie accepts but Varsin admits he was going to destroy them anyway.
A space alien bounty hunter chick who was wanted in several nebulas for kidnapping and information trafficking. She was ordered to find and capture Kiva Andru so her clients could extract information from her brain.
- The Beastmaster: Imprisons a race of giant Rhino-like aliens to serve as her minions.
- Bounty Hunter: Contracted to hunt down Kiva.
- Dark Action Girl: Certainly qualifies.
Robot warriors of the empire of the Halcyon Worlds. The only named robots are Zanzor and Gyvven. When Coop accidentally destroyed the Flame of Azeroth, their sacred treasure, the Emperor issued a challenge to the robots who were competing to claim his throne: bring him the robot who destroyed the flame to face judgment
- Blood Knight: Their entire race loves to fight.
- Epic Flail: Zanzoar's weapon of choice is a flail.
- Exact Words: Zanzoar allows Gyvven to capture Megas so that he can steal Megas from him as the throne goes to whomever returns with Megas.
- Expies: Zanzoar and Gyvven are expies of Optimus Prime and Megatron respectively, right down to sharing their original voice actors. Design-wise, Zanzor is based on the Trope Maker of the Humongous Mecha genre Mazinger Z (with a name reminiscent of US adaptation Tranzor Z) and Guyven is based on Transforming Mecha Trope Maker Raideen.
- Human Shield: Gyvven blocks Megas' sword attack by using one of his fellow knights as a shield.
- Join or Die: Gyvven offers to let Coop go unharmed if allows Gyvven to turn him in but Coop refuses.
- Removing the Rival: While hunting for Megas, Zanzoar was more than happy to destroy a fellow knight to eliminate the competition.
- Spikes of Villainy: Gyvven's weapons of choice.
- You Are Already Dead: Zanzoar dies the moment he realizes Coop has cut him in two with the Metal Maiden sword.
- Blood Knight: He's essentially a more unhinged and aggressive version of Coop, if that's even possible. Defeating the Glorft did not satisfy Coop, triggering his descent into evil.
- Character Tics: Still has Coop's habit of dusting his hands off after winning a fight.
- Char Clone: He's based on Char Aznable from Mobile Suit Gundam, with his mech bearing a noticeable resemblance to Char's Sazabi. Ironic, since his enemy is an alternate version of himself.
- Evil Twin: Obviously, he's an evil version of Coop.
- Final Boss: As the show ended up cancelled after the 2nd season finale, he became the last villain faced in the series.
- Foil: To Coop. Coop is a fat, bumbling hero while Evil Coop is a muscular, serious villain. This can also be seen in how Evil Coop ultimately abandons his Megas, despite it being in perfect condition, for a more war-like mech while Coop refused to leave Megas even after it was heavily damaged and about to explode.
- Formerly Fat: After he turned evil, he started working out to drop all the extra weight and get buff. Our Coop is far more offended by that than he is about him turning evil.
- Hero Killer: Destroys and possibly kills his universe's version of the S-Force, R.E.C.R, Magnanimous and T-Bot. Best exemplified by the fact that he actually destroys Megas.
- Knight of Cerebus: His arrival marked the one time the show took itself semi-seriously. He's so dangerous that Coop actually abandoned his usual strategy of attacking blindly and planned beforehand on forcing Evil Coop through the dimensional gate and forcefully shutting it while he's still in it in order to defeat him.
- Hoist by His Own Petard: Turns out he was sentimental enough to stash his own Megas away even though he claimed it as "a toy". Good Coop ends remembering these words after his Megas is destroyed and he takes it as his own. Since it was a lot more souped up, it allowed him to be on par with Evil Coop in the final battle.
- Omnicidal Maniac: Although he's described as a galactic conqueror, this is probably more accurate given that he's more interested in just laying waste to everything he finds.
- Red and Black and Evil All Over: His robot's color scheme is black and red.
- Rocket Punch: His mech has a proper version of this, unlike Megas which just shoots its fist, which is shown to be powerful enough to generate an explosion comparable to a nuke.
- Screw This, I'm Outta Here!: Upon realizing that he and Evil Kiva are heavily outnumbered by Coop and the Glorft army, he decides to retreat back into his own dimension.
- Shadow Archetype: He appears to be a future version of Coop who became more invested in fighting with MEGAS to anything else in his life and it consumed to become a monstrous madman. The way Future Jamie speaks, he used to be just like our Coop, but years of fighting the Glorft left an effect on him. As he notes, something happened to him that just had him keep fighting.
- Unlucky Thirteen: A bad guy with the number thirteen painted on his armor.
- Walking Spoiler: His entire existance is this due to being the twist at the end of "Rearview Mirror, Mirror Part 1".
- Cybernetics Eat Your Soul: After becoming Coop's Dragon, she was outfitted with cybernetic implants that apparently keep her hooked up to her mecha since she is never once seen outside of it throughout the episode.
- The Dragon: She's the main minion to Evil Coop.
- Evil Counterpart: To Kiva. Unusual because Kiva is not even aware of her existence.
- Fallen Hero: To the Earth Coalition Space Force who sought to defend humanity against the threat of extinction by the Glorft. Following the death of her dimensions' Gorrath in the early 21st Century, she sought to return back to her own time, only for her to suffer from Motive Decay that by the time of Rearview Mirror, Mirror, she now serves as Evil Coops' Dragon in ultimately destroying civilization on Earth.
- Motive Decay: In the alternate universe where Coop conquers the world, she follows him for several years ostensibly with the goal of returning to her own time. After a while, she gives it up to rule by Coop's side. ALT Jamie who was in love with her before she turned declares her irredeemable and put her on his kill list.
