Characters / Aaahh!!! Real Monsters

The Power Trio

Voiced by: Charlie Adler

Our main hero, flawed as he is. Son of the legendary Slickis, he has a lot to live up to... but his Ugly Cuteness, nervous disposition and self-confidence issues combined with his tendency to slack off keep working against him. Still, one shouldn't underestimate him based his looks or personal problems; his scaring skills are nothing to laugh at...

  • Art Evolution: In "The Switching Hour: Part 1", he has noticeable temple arms next to his eyes suggesting that he wears glasses. Later episodes, he doesn't have them.
    • He's actually wearing glasses while disguised as a human kid in "The Switching Hour: Part 2" (clearly visible underneath the backwards ball cap he dons even though the kid he's imitating didn't wear glasses, which suggest Ickis already had a pair with him), and Ickis wears glasses in most scenes from "Monsters Get Real" which was intended to be the series pilot. Either he switched to contacts later, or the animators got tired of drawing them.
  • Acquired Situational Narcissism: Give him a situation where he temporarily gets popularity, riches or notoriety... and about five seconds. Hello again, cocky-ass Ickis!
  • Aesop Amnesia: A chronic case. See above.
    • To be fair, he always becomes cocky for a different reason (he completes a successful scare and gets praised by the Gromble and Dizzle, he's farther along on his homework than Oblina for a change, he finds a bunch of toenails and is temporarily wealthy, he's new in school and thinks having a famous father automatically means he will be respected and revered simply for existing.) The Aesop is never presented as "don't be cocky" but "don't be cocky if *insert situation* happens" so it's likely Ickis never makes the connection that cockiness all by itself is annoying or wrong.
  • Berserk Button: Being mistaken for a bunny. He's not cute!
  • Big Damn Heroes: Surprisingly good at these when he put his mind to it.
  • A Boy and His X: Once adopted a puppy that he named Fungus and tried to hide from the Gromble.
  • Brilliant, but Lazy: Despite his self-doubt, he actually had real talent and wit; however, he spent a lot of time slacking off and neglecting his scares, leaving them to the last minute... and then panicking about it.
  • Catch Phrase: "I hate my life." Doubles as a Shout Out to Rocko's Modern Life, where Ed Bighead (also voiced by Charlie Adler) expresses the same refrain. He has a few other repeated sayings like "On the good foot!", "I'm bad!" and "No way!" that are used sporadically, but not quite to the same extent as "I hate my life."
  • The Chosen One: There are definite elements of this. In the first season, "Where Have All The Monsters Gone", The Great Pool, the collective embodiment of all monsters, declares Ickis is the one who will lead the other students to rectify the lack of fear crises — which he does. In the second season, Ickis is the monster selected to undertake the once every 400 years quest to find the Holey Pail; this is a big deal in monster society, and the last monster to quest for it was none other than the Gromble.
  • Clark Kenting: His Super Monster costume is nothing more than a towel for a cape, and underpants for a mask. It does at least cover his ears, which seem to be viewed as his most distinguishing feature.
  • Crouching Moron, Hidden Badass: Most commonly kind of goofy, but when he gets serious...
  • Cute but Cacophonic: Ickis is the least scary-looking of the regular monsters, but he has a very high-pitched voice. This isn't entirely a bad thing in monster culture; when he and Krumm are mashed together to become Krickis, Krumm is genuinely pleased he can now whine like Ickis does.
  • Fantastic Racism: When Ickis becomes spontaneously combustible, almost all the other monsters react with fear and refuse to be around him. Horvak takes it the farthest, by actually pulling Krumm out of the Academy temporarily.
  • Forbidden Fruit: Was absolutely fascinated by human culture, despite the Gromble forbidding everything to do with it.
  • Guile Hero: Since he didn't have much in the way of sheer physical strength, and going One-Winged Angel couldn't solve all his problems, he tended to rely more on quick thinking and Indy Ploys.
  • Hidden Depths: Ickis is a surprisingly good dancer, as shown in multiple episodes.
  • Inferiority Superiority Complex: Inverted; he has one, but instead of the high-and-mighty airs being his default mode, he only assumes them when given the opportunity. The rest of the time, the emotional mess underneath is fully exposed.
  • Interspecies Friendship: While monsters in general seem to look down on humans, Ickis really seems to be quite amiable towards them; whilst he still scares them because he has to, and enjoys doing so, he really does sit in Punch Clock Villain territory with the fact he's quite companionable towards them if given the opportunity. He makes fairly good friends with Bradley, despite their less-than-stellar first meeting, and in one episode becomes attached to a blind old blues player to the point of going on one of his most impressive physical transformations to help him.
  • Jock Dad, Nerd Son: His father has won a few trophies, and ribbons, and plaques, and more trophies... A recurring theme is Ickis despairing of ever matching the Great Slickis' exploits. It's telling that when the Gromble forces him to become a last minute entry in a wave-riding competition, the same competition that his father NEVER lost, everyone is betting on Ickis... to lose. In a surprising twist, Ickis proves that he could have won that event, but gives up a sure victory to go back and save Krumm.
    • Unusually for this trope, however, his father isn't really that demanding and is quite understanding that his reputation is a lot to live up to. In his introductory episode, he deliberately showcases one of his own embarrassing failures to help his son realise that even The Great Slickis didn't start out so great, and he's highly proud of Ickis's above mentioned moral victory.
  • Keet: He's the most manic and hyperactive of the three heroes.
  • Killer Rabbit: Ickis's transformations include fangs and claws that certainly look quite nasty, even before he starts growing larger. Even when he doesn't have them, he's got a nasty bite, and he's actually pretty good at making scary sound effects (screeching, scraping claws, gnashing fangs). It's usually when he appears and people see how much like a rabbit he looks that they tend to stop being scared.
  • Large Ham
  • Let's Get Dangerous: When the chips are down is when Ickis tends to forget about his issues and just go with his instincts.
  • The McCoy
  • Mood-Swinger: Depending on the moment, he could go from cocky Jerkass to wide-eyed naivete to Deadpan Snarker to panicky Woobie.
  • Mr. Vice Guy: If an episode is going to focus on a monster developing a vice, it's usually going to be Ickis.
  • Naive Everymonster
  • Nerd in Evil's Helmet: An inversion, in that Ickis normally looks cute and cuddly, with his truly monstrous side hidden until he manages to trigger a transformation.
  • Not So Different: From his father or the Gromble.
  • Other Me Annoys Me: Is conned into creating 5 clones in one episode. The clones fulfill his 5 scares in a day assignment, enabling him to play Sewerball. In a rare moment of glory Ickis wins the game. Too bad for him the clones escape from his dorm and annoy The Gromble, The Snorch, Zimbo, Krumm and Oblina, leaving Ickis highly upset.
  • Parental Issues: He's deeply concerned about trying to live up to his famous father's reputation.
  • Ping-Pong Naïveté
  • Red Eyes, Take Warning: A signal he was going to start looming was his eyes turning red. The accompanying noises made it sound like they were actually filling with boiling blood.
  • Sensitive Guy and Manly Man: The sensitive guy to Krumm's manly man. Sometimes, this can be inverted between the two.
  • Ship Tease: The clone Ickis seems to regret the most is Chickis, the lecherous clone who tries to kiss Oblina, which he claims he will never be able to live down. Bear in mind that Ickis got awfully jealous when Oblina was squishing on the popular Gludge, once confessed that he didn't know what he would do without her, and his version of how they scared an operahouse full of humans had Ickis rescuing the nervous, starry-eyed Oblina who all but swoons over his bravery.
  • Size Shifter: Called 'looming' or 'growing', which also functioned as a One-Winged Angel mode for his victims. Of all the monsters, he seems to be the most adept at it, once growing bigger than an apartment building.
  • Strong Family Resemblance: He's basically a somewhat scrawnier version of his dad.
  • Ugly Cute: In-Universe, this is how humans react if they actually see him. Seriously; in one episode, a nurse he has terrified to the point of cowering in fear whilst he was in the shadows immediately calms down and starts cooing over how cute he is upon seeing him in the light. In another, a man with a nervous disorder that makes him terrified of literally everything — to the point he's seen screaming in terror of a chair and his own bed — just smiles and cuddles Ickis on first seeing him, calling him "teddy".

Voiced by: David Eccles

Ickis's best friend and fellow underachiever, a squat, hairy pink monster with free-rolling eyes that he normally carried around in his hands. Cheerful and carefree, he never stressed about scaring as much as his roommates, just enjoying whatever misadventures they got into.

  • Brilliant, but Lazy: Krumm is actually more intelligent than he lets on (much to the surprise of The Gromble), to the point where he's actually scored second behind Oblina in scaring at least once. He only acts dumb because there's less pressure on himself.
  • Cephalothorax: He's basically a giant, hairy mouth/belly combo with stubby limbs, a big nose and a pair of free-floating eyeballs.
  • Curse: Suffered from the Curse of the Krumm, a complete loss of his trademark hideous stench, for a period of time, but managed to break it with the help of his friends.
  • Eyes Are Unbreakable: Well, his father's fate implies they can be destroyed, but fortunately they're a lot tougher than human eyes.
  • Eyes Do Not Belong There: Krumm carries his eyes around in his hands, allowing him to put them wherever he wants. He usually sticks them in his mouth if he needs to use his hands.
  • The Fool: He's the goofy one of his friends.
  • His Name Really Is "Barkeep": His family is called "the Krumm". Apparently, Horvak wasn't very imaginative when it came time to name his son.
  • The Kirk
  • Loser Son of Loser Dad: Downplayed. His father Horvak flunked out of the academy and became a muck farmer, and the Gromble doesn't exactly expect a whole lot out of Krumm himself. Krumm seems pretty okay with this, though.
  • Sensitive Guy and Manly Man: The manly man to Ickis' sensitive guy. Sometimes, this can be inverted between the two.
  • Strong Family Resemblance


Though her family had enough toenails that she could lounge in the lap of luxury for the rest of her life, Oblina chose to attend the Monster Academy. Since she could pull her insides out, she quickly became top scarer in their class, despite having two of the worst students as her roommates. Frequently tries to get them to take their studies more seriously, and isn't above gloating whenever ignoring her advice gets them in trouble... but isn't above the antics herself, and still considers them her best friends.

  • Action Girl: Or the scarier equivalent.
  • Balloon Belly: Because of how slender she is, when she eats something, it tends to visibly bulge through her skin as she swallows. A focal point in "Internal Affairs", in which she becomes infested by a parasite-monster that forces her to consume random junk to decorate his new home in her stomach, to the point it's feared she'll eventually rupture something.
  • Becoming the Mask: Happened once; while disguised as a human to gather information on them, she had a bad reaction to cotton candy and ended up believing she was really human.
  • Braces of Orthodontic Overkill: After a youthful indiscretion of brushing her teeth once, she had to get a set of these to unstraighten them. This grabbed the attention of the Romantic False Lead — or rather, his reflection off of them did...
  • Growling Gut: This happens to her in "Internal Affairs".
  • I Warned You: A common refrain on her part.
  • Insufferable Genius
  • Lonely Rich Kid
  • Not So Above It All: Despite her complaints, she could get swept up in things just as easily as her roommates. While she often derided Ickis' fascination with human culture, that didn't stop her from being entranced by The Lamp, or developing an obsession with Westerns, and so on and so forth.
  • One-Winged Angel: You know the one...
  • Parental Issues: She's got.....mommy issues.
  • Slapstick Knows No Gender: Is just as prone to the receiving end of Amusing Injuries as her other two friends.
  • The Spock
  • Teacher's Pet: She's the Gromble's personal favorite.
  • Toilet Humor: She burps when she eats a shoelace, which, sounds quite weird.
  • What the Hell Is That Accent?: Speaks with a vaguely British accent, even though she is an American monster. Notably, her parents have a different accent.
    • In the Mexican Spanish dub, she speaks with a notable European accent in her voice, possibly in a attempt to sound her like another classic monster.

Staff Members

The Gromble

Voiced by: Gregg Berger

Headmaster and head teacher, The Gromble certainly isn't afraid to berate, belittle and punish his students whenever they falter in their scaring or studies. Particularly likes to single out Ickis and his friends — though admittedly, they do bring a lot of it down on themselves. For all his harshness, he really does care about his students and wants to see them succeed — even if he has to beat every scrap of hard work out of them!

  • Agony of the Feet: Those fetching red high-heels were accidentally obtained during his first trip into the human world... when they got wedged on his feet.
  • Badass Teacher
  • Camp Straight: He was melodramatic and wore red pumps, but in one episode had a crush on the female librarian.
  • Creepy Crossdresser: For some odd reason, he wears high heels on his feet. He's even got a room full of them.
  • Dean Bitterman
  • Expy: The Gromble was patterned in voice and design after the head Blue Meanie.
  • Jerk with a Heart of Gold: See Pet the Dog
  • Large Ham
  • Nice Shoes
  • Not So Different: It was implied several times that when he was Ickis' age, he suffered a lot of the same problems and stumbling blocks.
  • Papa Wolf: He'll go to great lengths for his students, and doesn't care if you're a member of his academy or not if he catches you toying with his students he will make you regret it.
  • Pet the Dog: Getting these moments now and then showed how much he really cared about his students.
  • Red Eyes, Take Warning: A key indicator that you really ticked him off is that his eyes turn red (much in the same manner as Ickis' when he starts to loom, complete with the blood filling sound)
  • Sadist Teacher/Stern Teacher
  • Spell My Name with a "The"
  • Strong Family Resemblance: To his mother.
  • Vague Age: Possibly a Retcon? In one episode he was depicted as a young teacher just starting his career in the late 1700s, and another has him as a child in the 1920s.
    • Teaching in the 1700's is more probable. He embarked on the Quest For The Holy Pail when he was a student... 400 years ago. The Gromble would have to be really 500 years old for some of his comments to even make sense, although it still seems like an exaggeration to say he hasn't seen another monster in centuries.
  • Verbal Tic: Switches between a sweet (and extremely sarcastic) tone of voice, a sinister growl, and over-the-top screaming at the drop of a hat.
    The Gromble: Oh, Master Ickis, how inquisitive you are today! It is so ANNOYING!!!

The Snorch

The Unintelligible monster who handles all the Cool And Unusual Punishments rule-breaking students have to suffer. Very intelligent, with a love for the very same things he uses as punishments, like opera and square dancing. Unfortunately, the communication barrier makes it difficult to share his interests and thoughts with others...


Voiced by: Tim Curry

As the only monster capable of understanding The Snorch — and a craven little coward with a tiny body and no real physical strength of his own — Zimbo likes to stick close to The Snorch and leech off his fearsome reputation. Also uses his size to his advantage by spying on the students and reporting back to The Gromble.

Parental Units


Voiced by: Billy Vera

Ickis's father and the most famous graduate of Monster Academy. Living up to his legacy is quite the responsibility...

  • The Ace
  • Acrofatic: Flashbacks show him as a chubby bonsty, and even nowadays he's quite a bit broader and heavier than Ickis. Yet Slickis still has an easy time scaring humans, can stand up to a tank, and is great at monster sports (evidenced when he bowls a perfect game of Gorblats.) He might be a Big Eater as he cheerfully suggests buying a large amount of Slime Pies, and his first choice when listing father/son activities was to go forage for food.
  • Boisterous Bruiser: Extremely friendly, cheerful and happy, making yet another stark contrast with his emotional son.
  • Generation Xerox
  • Minor Major Character: He's one of the most famous monsters to have ever graduated from the Gromble's Academy and father to Ickis, yet he only appears in 5 episodes (one of which is a flashback, and another is part of a dream sequence.)
  • Not So Different: Has admitted that he didn't have the easiest time in school and was a lot like Ickis.
  • Papa Wolf: Risked his own life to save his son's from being flattened by a tank in a botched scaring attempt certainly counts
  • Parental Issues
  • Scars Are Forever: As an adult his ears are torn in several places.
  • Strong Family Resemblance: Was a little taller than Ickis and had a stockier, sturdier build.


Krumm's father, an equally cheerful monster who makes his living as a muck farmer. Has only one eye, and wears a black glove over his empty hand.

  • Curse: Like his son, suffered the effects of the Curse of the Krumm. Unlike his son, was never able to break it, and lost his stench for good.
  • Eyepatch of Power: Wore a black glove over the hand that was supposed to hold his lost eye.
  • Eye Scream: He attempted to scare people in pre-Revolutionary America, but dropped one of his eyes as a soldier dropped a box of musket balls. The soldier grabbed Horvak's eye by mistake, loaded it and... well, it was the Shot Heard Round the World.
  • Fantastic Racism: He doesn't want Krumm to attend class with a combustible monster, and tries to come up with an excuse for Krumm to leave.
  • Generation Xerox
  • Perma-Stubble
  • Strong Family Resemblance: Basically looked like an older version of his son (minus one eye).


Oblina's rich and overbearing mother. She disapproves of her daughter becoming a common scarer, and would much rather see her return to the lap of luxury.

  • My Beloved Smother
  • Rich Bitch: Looks down upon other monsters who aren't as wealthy, and thinks that her daughter's dreams of becoming a great scarer are beneath her.


Oblina's meek and submissive father, who only wants to see his wife and daughter happy.

Important Humans
"They want evidence? I'll get 'em evidence!"

Simon D. Hunter

Voiced by: James Belushi

As his title implies, Simon is a self-declared monster hunter, determined to break the masquerade and prove once and for all that he isn't insane. Develops a very personal grudge against Ickis after the little monster thwarts his plans and keeps humiliating him. His surname and middle initial were given in his expired driver's license in the episode "Battle of the Century."

  • Even Evil Has Standards: Despite constantly trying to capture the monsters, Simon means no particular harm to them. In the episode "Showdown" he even rescues Ickis from some more ruthless monster hunters who want to kill Ickis instead of capturing him alive.
  • The Hunter
  • Humongous Mecha: Pilots one in "Battle of the Century."
  • Meaningful Name: Simon D. Hunter...Simon the hunter.
  • It's Personal
  • Large Ham: He knows how to make a entrance.
  • Not-So-Harmless Villain: Whenever the monsters push him too far, he goes to extreme levels to catch them by force.
  • Small Name, Big Ego
  • Stupid Evil: Most of his failures to catch a monster is his own fault. For example, in one episode, he finally succeeds in catching Bigfoot...and he would've succeeded in showing everyone proof if he didn't waste time reading such a long list, thus giving the other monsters time to free Bigfoot before he is exposed to the humans.
  • They Called Me Mad!


Voiced by: Brett Alexander

A somewhat nerdy young boy who became curious about monsters after first encountering them. Briefly became Simon's apprentice; however, when Ickis told him what would happen if monsterkind was revealed to humanity, he promptly helped them escape and became a Secret Keeper.
