     Tyler "Ty" Archer
Voiced by: Michael Cohen

Abby's younger brother and the other main character. He is very intelligent, possessing a cool, active and analytical personality that takes everything in.

     Paul "Lab Rat" Squirfenhender
Tech support for the Bureau of Grossology, and a friend of Ty and Abby. He is always accompanied by his pet rat, Hermes.

     The Director

Once a promising young university student who wanted to study entomology (the study of insects) until she discovered how insects are treated by science: captured and dissected. Now, armed with all sorts of bugs, she pursues an insect agenda, to wipe all people off the planet so bugs can rule again.

The Slim Slime Man
A bitter old sewer worker, who abnormally fused with a living slime mold while working in the sewers one day, becoming a strange giant slime creature with a ghoulish skull-like head seen inside. As he gets more powerful, he aims to cover the surface world with living slime molds.
  • Benevolent Boss: He treats his slime mold minions like a group of kindergartners, even telling them to pick a "surface buddy" for their invasion of the surface world.
  • Blob Monster: Part-man, part-slime mold.
  • Glowing Eyes of Doom: His eyes glow yellow.

Originally just an ordinary kid until his older brother Gary tortured him by stuffing his brother under the bed sheets and farting in there. For fifteen years, he became adapted to breathing the gases in farts. Like a fish being out of water, clean air is toxic for him, so he breathes toxic gases in a dome that he wears on his body. There was only one thing Fartor wanted... revenge on his brother Gary.
  • Amazing Technicolor Population: Has blue-grey skin.
  • Benevolent Boss: His kind treatment of Ty even after brainwashing him into becoming his minion.
  • Body Horror: He was normal human who mutated into a bloated, grey-skinned, methane-reliant monstrosity.
  • Fartillery: It's all in his name.
  • Gasshole: His abilities revolve around farting and he even breaths methane as a substitute for oxygen.
  • Gonk: Post-mutation.
  • Powered Armor: He wears this to help him breath and fly around.
  • Tragic Villain: His motivations are more out of spite over his condition than out of evil.
  • Used to Be a Sweet Kid: He used to be a normal kid named Larry, until his brother's constant Dutch Ovens caused him to mutate into Fartor.
  • Woobie, Destroyer of Worlds: Started out as a normal kid who suffered abused by his brother, now turned into a villainous abomination.

Sloppy Joe
An extremely dirty man who after discovering that a whiff of his stink was enough to render people unconscious, vowed to never let a drop of water, soap, or deodorant touch his skin again, and turned to an easy life of crime.
  • Amazing Technicolor Population: Sickly greenish-yellow skin. Subverted as it's actually the filth coating him.
  • Ambiguously Human: He looks more gorilla-like than human.
  • The Brute: His large size and strength makes him a threat.
  • Evil Albino: He's actually one, and only appears green because of how much filth he has on him.
  • Fat Bastard: Overweight and a nuisance to everyone around him.
  • Fat Slob: He isn't called "Sloppy Joe" for nothing.
  • Gonk: Not exactly in the good-looking department.
  • Not-So-Harmless Villain: Most of the time he's more of an annoying petty criminal than actually dangerous, but it's shown that some of his actions can have disastrous consequences, such as in "Yack Attack".
  • Obliviously Evil: Occasionally he can fall into this. In "Yack Attack", he just wanted to go for a swim in his own quiet vacation spot. The problem is that his "vacation spot" was actually the city's water supply, and he was unknowingly passing his germs to everyone and making them extremely sick.
  • Pet the Dog: Turns out he has a soft spot for Christmas, and genuinely tries to be cheerful and spirited in "Let Them Eat Fruitcake", even giving Abby a present.
  • The Pig Pen: Sloppy Joe is covered filth and all of his plans tend to involve filth in some way.
  • Uncleanliness Is Next to Ungodliness: No surprise there, since his gimmick is that he never bathes and uses his filth as a weapon.
  • Weaksauce Weakness: Clean water or just taking a bath in general. While it doesn't really hurt him, he hates it and being sparkling clean will leave him with a Villainous BSoD.
  • Yellow Eyes of Sneakiness: Has yellow eyes, and is a criminal.

The Scab Fairy
A crazed former beauty queen who was traumatized over a small cut to her shoulder, ending her career. Not seen since then, she used her exceptional degree in dermatology and mythology to create a high-tech dragonfly-winged suit made of scabs, and takes the identity of the Scab Fairy, based on a Tooth Fairy-like myth figure that collects scabs (rather than teeth). She is armed with a high-tech wand that removes scabs from people's wounds, and inflicts them on others. Her ultimate obsession is to inflict scabs on anyone pretty, as revenge for the loss of her old beauty queen career.

Lance Boil
Once a successful Grossologist; however, he envied The Director's authority. Boyle tried to pull a coup, using a "prototype shrink-ray." Ty had tinkered with the weapon though, and Lance ended up blasting himself, causing himself to shrink and his head to turn into a giant boil. Banished from the team, he decided to use his skills for evil, with one goal in his twisted head revenge against all Grossologists, especially Abby and Ty.

Keith "V.K." Van Kobbler
A popular and undefeated young basketball player, and Abby's former idol. Endorsed the "KVK-1" brand super-sneakers, with a twisted method behind his fame; he single-handedly manufactured the KVK-1 sneakers for mass consumption, and spiked them with fungus (while wearing a non-spiked "Deluxe Edition" pair for himself, of course), so that everyone will have foot fungus, and most of all, eliminate the competition, so that he will be the only basketball player in the world.

Mr. Fowler
The custodian at Ringworm Junior High School. He grew tired of cleaning up the excess pigeon poop around the school, so he built a giant mechanical owl suit, with which he captures pigeons and plots to put them in a pie to bake them.

Chester/Kid Rot
A teenager who, after a science experiment mishap while trying to find a cure for foods going bad or rotting, gains the "rotting touch," with which he causes all organic materials to rot with a single touch, and also gives off a horrible smell. He becomes a new student at Ringworm Junior High School, and causes chaos upon his arrival, with a concerned Abby and Ty trying to cure him. But Chester's rotting powers literally go to his head, giving him a twisted personality, even christening himself "Kid Rot", and making him a formidable and diabolical foe for the Grossology team. Worse, he has a psychotic infatuation for Abby who ultimately hates his prevalent Kid Rot persona, and will stop at nothing to win her heart, even going as far as to rot the entire world.

Dr. Cornelius Colon
A mad proctologist, who plots to engulf the world in a gigantic colon, starting with Ringworm Junior High School, to take revenge on people for unsympathetically making fun of him for his unfortunate surname. He has giant tapeworms as henchmen.

A giant monster made of nose mucus stolen by Sloppy Joe using a suction gun, who simply wanted to make a "boogerman" with said mucus much like a snowman. Abby and Ty confront Sloppy Joe, and in the process, inadvertently cause an electrical accident that brings the "boogerman" to life. The monster sucks mucus out of people's noses, and the more he consumes, the larger he gets.
  • Blob Monster: Made entirely out of snot.
  • Weaksauce Weakness: Its only weakness is dirt particles just like any mucus, which cause him to not only dry up, but decrease in size.

Darko Crevasse
A gothic caped villain whose eyesight is accustomed to darkness. He summons a huge flock of bats to drop guano on anyone who opposes him. As he cannot stand light, his ultimate plan is to plunge the city into eternal darkness.

Sarah Senia
A lady whose DNA structure was crossed with that of plants. Plotted to use giant carnivorous plants to attack the city, and ultimately, the world.

Insectiva's twin sister. Unlike Insectiva, she loves arachnids, as her name suggests. She and Insectiva have had a bitter rivalry, and both pit their own respective arthropods against each other, with catastrophic results.

Frederick Follicle
A hair dresser who doesn't like to change styles. After getting kicked out of a job, he went underground doing biological experiments, and ended up with living hair.

Roger Pink-Eye
A kid with a pink eye. He is curious about Ty and Abby's extra-curricular activities, and thus sets off to find the truth about his classmates' secret identities, using various attempts to do so that ultimately end in failure. He eventually becomes a Grossologist, but he is fired/quits after his plan backfires with Lance betraying him.

Basso Profondo
A disgraced opera star, who was once part of the Three Baritones. He's back for revenge, but this time he's singing a whole new tune; in other words, he's now a burping star.
  • Balloon Belly: Turns out that Basso is obese because of all the gas built up inside him.
  • Big Eater: Eats a lot of meat and other rich foods, which help fuel his burping powers.
  • Evil Sounds Deep: Has a baritone voice, though it's noticeably higher when he's skinny.
  • Fat Bastard: Though he's actually just bloated, rather than fat.
  • Fat Slob: If his powers didn't already tip you off, his eating habits are disgusting as well, gorging nonstop on greasy foods and his shirt even being covered in grease stains.
  • Karma Houdini: His episode ends with him running away, presumably getting away scott-free with his destruction and havoc.
  • Jerkass: He is extremely rude to Mr. Archer even after the latter stated he was a huge fan of his.
  • Gasshole: His burping abilities.
  • Gonk: Probably not as much as some other villains on this show, but he's still in no way pleasant-looking, even before getting extremely big.
  • Make Me Wanna Shout: His sonic belches serve as this, even being able to shatter glass.
  • Ominous Opera Cape: Naturally, due to him being an opera singer.

Gary Gumdrop
A crazy man with a big sweet tooth and a lot of rotten teeth. His plan is to make super tooth-rotting candy, pretending that they'll take care of your teeth, and distribute them to everyone, so he won't be the only one with a rotten mouth and a large craving for candy.

Gundy McGoober
An old man running a campground who is tired of campers bringing their new electronic devices with them, so he uses mutated worms to scare away people from his lake.
  • Grumpy Old Man: To a villainous degree. He doesn’t like campers playing with electronics, so goes to great lengths to get rid of them.
  • Well-Intentioned Extremist: He only wants to get rid of the "city folks" because of how disruptive they are, although scaring them away is probably a bit too much.
