Major Characters

    Mouse Fitzgerald 
https://static.tvtropes.org/pmwiki/pub/images/mouse_9.png
Not drunk enough.
Voiced by: Matt Maiellaro, Seth Green (Invictus)
Mouse Fitzgerald, nicknamed Fitz and also known as Butch, is the main protagonist of 12 Oz. Mouse. He is a green mouse who displays sociopathic, alcoholic, amnesiac, and anthropomorphic behavior very often. He usually relies on comedic responses or a roundabout figure of speech instead of straight answers. Most of the first season involves him and his best (and only) friend Skillet causing havoc in the town, while in the second season focuses on the dual's struggle against Shark and Rectangular Businessman, the former originally being his work boss. He drives a yellow jet with "TAXI" written on both sides. He was employed by Shark, but he is very cautious around the latter.

He works for Shark, but neither of them trust each other very much at first — a suspicion that turns out to be completely justified later on, with the second season focusing on him and his cohorts in a conflict with Shark and Rectangular Businessman that seemingly has the world around them at stake as Fitz tries to make sense of who he was in a past life.


  • A Dog Named "Dog": He is a mouse whose first name is Mouse.
  • Alcoholic Parent: Is an alcoholic who had a wife and a daughter.
  • The Alcoholic: One of the main themes of 12 Oz. Mouse is Mouse Fitzgerald being an alcoholic. In fact, it is his defining trait. He usually gets drunk as a reward for performing various odd jobs, such as robbing the bank in the first episode. He frequently goes to Rhoda's Bar and the Liquor Store to start drinking lots of bottles of alcohol (whether it be beer or liquor), which interferes with his memory.
  • Amazing Technicolor Wildlife: Fitz is a green mouse.
  • Amnesiac Hero: For a real loose definition of "hero", but yeah. The ongoing narrative throughout the first two seasons essentially sees Fitz following what clues he can find to determine who he once was.
  • Anti-Hero: Fitz and Skillet have no problem robbing banks, killing off human citizens, and then getting drunk as their reward. At least they aren't trying to destroy/control the whole world.
  • Cool Car: He has one very cool taxi that appears to be a yellow jet with no wings.
  • Funny Animal: Indeed, but Mickey Mouse he is not, bearing a closer resemblance to a talking rat.
  • Happily Married: To his wife, Woman Mouse before her disappearance.
  • Talking Animal: Mouse Fitzgerald is a green anthropomorphic mouse that has the ability to talk like an actual human being.
  • Villain Protagonist: More so in the earliest episodes, before the show's Myth Arc places Fitz on the grey end of Black-and-Grey Morality.

    Skillet 
https://static.tvtropes.org/pmwiki/pub/images/screenshot_2019_01_01_at_91134_pm.png
drum solo
Skillet is the secondary protagonist of 12 oz. Mouse, an ever-screeching chinchilla. He never speaks English but instead screeches to communicate. He has rocket feet, laser eyes, and also plays the drums. He is Mouse Fitzgerald's best friend.
  • Anti-Hero: He’s an agent of chaos much like his buddy Fitz, but they aren't actively malicious the way Shark, RBM, and the Clock are.
  • Back from the Dead: He died in the Season 2 episode "Farewell", and was later revived in the finale "Prolegomenon".
  • Funny Animal: Averted, he is a non-anthropomorphic chinchilla.
  • I Am Not Weasel: He is a chinchilla. The characters mistakenly call him a squirrel on numerous occasions.
  • The Unintelligible: He speaks not in English, but in frenzied chittering noises. Fitz seems to understand him just fine, though.
  • The Voiceless: Skillet doesn't have a voice, and speaks in screeches.

    Shark 
https://static.tvtropes.org/pmwiki/pub/images/shark3y.jpg
Got a job for you.
Voiced by: Adam Reed (originally), Rita Morales (briefly), Matt Maiellaro (briefly), Ned Hastings (currently)
Shark is one of the show’s primary antagonists. Initially seen as the president of an employment company (and possibly of the show's setting), he’s revealed to be involved in a large conspiracy against Fitz, alongside RBM. He's portrayed as an intimidating, yet soft-spoken creature who has a short tolerance for those around him. While he constantly threatens with violence, he actually prefers to use indirect means of assault (ex. hiring Pronto to assassinate Fitz) but does not hesitate to get involved personally once aggravated enough. He has a strong desire to remain in power, regardless of whatever situation occurs.
  • A Dog Named "Dog": Like Mouse, there's not much ambiguity about what he's got goin' on.
  • Art Evolution: Shark's design gets a subtle change in "INVICTUS”. Rather than being a direct rip of the “Old Kentucky Shark” clip art (purported to originate from Sealab 2020 and most well known for appearing in an episode of Space Ghost Coast to Coast prior to being repurposed for 12 oz. Mouse), he’s fully animated like everyone else, granting him a fuller range of movement. (Doesn't fix his mobility issues, though!)
  • Back from the Dead: After his death at the end of Season 2. In "INVICTUS" he appears alive & well with no explanation, however, he does get killed by Fitz.
  • Bad Boss: Shark started to became this starting with the fifth episode "Rememorized" where he showed a supposed threat to his employee Mouse on television. Shark revealed the threat to be Pronto, a deadly archer.
  • Big Bad Duumvirate: Shark & The Rectangular Businessman are the two big bads of the show.
  • Cool Ship: His ship is very cool as it appears to be a giant flying metal shark.
  • Immune to Bullets: In the first episode, "Hired", he was immune to Fitz's Bullets from his gun. Later subverted in "Farewell" where he was killed by the bullets of Mouse, Skillet & Cyber Green-Sweatered Woman.
  • Smug Snake: He tries his damnedest to come off like this, but it doesn’t really take. Mostly because he’s got RBM to compete with.
  • Talking Animal: Yep. Notably, the only animal-based character in the cast whose anthropomorphic traits are limited to thinking, speaking and breathing like a human, but not moving like one.
  • Threatening Shark: He's a shark and one of the main villains.
  • Vitriolic Best Buds: With Rectangular Businessman.
  • Weaksauce Weakness: Shark, being a non-anthropomorphic shark out of the water, has to drag himself slowly across the floor, and needs a special rig to move around his control room.

    Rectangular Businessman 
https://static.tvtropes.org/pmwiki/pub/images/rectangular_businessman.png
I hope you know how very lucky you are to know me since I'm so incredibly incredible.
Voiced by: Kurt Socclich
The Rectangular Businessman, also known as The No-Eyed Square Guy, is an arrogant pink square who claims to be an affluent businessman and continually references his enormous wealth, and one of the main antagonists of the show. He wears thick, rounded spectacles but has no eyes. Although partners, there seems to be a rivalry between Shark and the Rectangular Businessman, both imposing on the other on several occasions. Despite his arrogance, Rectangular has taken orders from Shark, albeit begrudgingly. He is able to use his mind to kill, and has used it for a number of activities, from teleporting a television to splitting open heads to transforming the Shadowy Figure into a dark liquid substance.
  • Back from the Dead: Like Shark, after his death at the end of Season 2, he appears alive & well in the special "INVICTUS" with no explanation. He later gets shot to death by the Cyber Green-Sweatered Woman.
  • Big Bad Duumvirate: Shark & The Rectangular Businessman are the two big bads of the show.
  • The Dragon: To Shark.
  • Eyeless Face: He wears a pair of glasses that hide the fact that he has no eyes. He casually reveals his face to other characters a couple of times over the course of the series.
  • Eye Glasses: He has blue glasses for his eyeless face.
  • Gentleman Snarker: He enjoys the finer things, and is petty AF.
  • Screw the Rules, I Have Money!: His modus operandi.
  • Sinister Shades: Is a villain who wears a pair of shades.
  • Smug Snake: He’s rich, wants you to know very much that he is rich, and frequently engages in Snark-to-Snark Combat with Shark in an ongoing attempt to one-up him.

    Clock 
https://static.tvtropes.org/pmwiki/pub/images/screenshot_2019_01_20_at_72846_pm.png
tick...tick...tick
Voiced by: Ned Hastings
The clock is a wall clock that can slide around on the wall and teleport. It appears to command Shark and Rectangular Businessman and can release "time gas" and "anti-language gas" that can affect people's minds. While Shark and Rectangular Businessman converse with the Clock as if it were their equal or superior, the Clock itself does not speak. It only makes a constant ticking sound. The Clock hands are stopped; characters state that the time is stopped at 2:22. In the Season 2 finale, the clock finally changes its time to 2:23.

    Rhoda 
https://static.tvtropes.org/pmwiki/pub/images/rhoda.jpg
I mean completely wild at a wildness wild-y. And I salute you.
Voiced by: Dave Willis
Rhoda is a one-eyed bartender that works at the Bar in the City. Though usually described as male, Rhoda's gender is unknown, being referred to with both he/him and she/her pronouns by various characters. Rhoda often serves Fitz and Skillet twelve beers at once, and appears to be a friend to Fitz, but is terrified and intimidated by Shark. Rhoda also believes that Rectangular Businessman and Roostre are the true evils in their society.
  • Ambiguously Human: He looks like a floating human head, possessing various human features.
  • Ambiguous Gender: Rhoda, who looks and speaks like a man, is sometimes referred to with she/her pronouns.
  • Back from the Dead: He is found alive in a jar in the special "INVICTUS".
  • Out of Focus: Due to his death in the Season 1 finale, he is more or less absent from Season 2.
  • Killed Off for Real: Averted in "INVICTUS". He dies when the Rectangular Businessman executes him by telepathically slicing his head in half to reveal a fire-breathing snake inside, implying that he's dead for the rest of the series... until his cameo in "INVICTUS".
  • The Bartender: He is your everyday bartender who works in his own bar.
  • The Bus Came Back: Rhoda (fully revived) makes a small cameo trapped in a giant jar alongside Liquor & The Bug in the special "INVICTUS".

    Man-Woman 
https://static.tvtropes.org/pmwiki/pub/images/screenshot_2019_01_30_at_84910_pm.png
Woman Power On!/Man Power Go!
Voiced by: Bonnie Rosmarin
Man-Woman is a woman that can change her gender and emit a loud air horn sound. She has the unusual ability to transform into a man after shouting the command "Man power, go!", and can transform back into a woman by saying "Woman power, on!". Man-Woman is also the owner of a diner.
  • Ambiguous Gender: She can switch genders at will, hence her name.
  • Back from the Dead: She is fully alive in the special "INVICTUS".
  • Flat Character: Unlike the Green-Sweatered Woman, Man-Woman's character is kinda flat. There is not that much about her except that she's a waitress with the ability to change her gender at will who also enjoys playing with a red ball, drinking beer, reading books and hates pizza. She doesn't really do much in her appearances, though, this is later subverted in the third season where it's revealed that she owns the Box of Worlds.
  • Out of Focus: She was absent in most of Season 2 due to being killed in an explosion in "Surgery Circus", she did make a return in "Meaty Dreamy" in a flashback and "INVICTUS" however.
  • Sensory Abuse: Makes loud, often abrupt, air horn noises.
  • Sex Shifter: True to her name, this is Man-Woman's main gimmick.
  • Shapeshifter Default Form: The woman form.
  • The Smurfette Principle: In the first few episodes, later averted with the appearance of the Green-Sweatered Woman.
  • They Killed Kenny Again: She died once in "Surgery Circus" when she entered a building saying "Cookies"; after this, she was absent for the rest of Season 2 (aside from appearing in a flashback in "Meaty Dreamy").

    Peanut Cop 
https://static.tvtropes.org/pmwiki/pub/images/screenshot_2019_01_21_at_100937_pm.png
Are you the one who broke in here... now?
Voiced by: Nick Weidenfeld
Peanut Cop, also referred to as "Peanut" (and simply "The Cop" in episode summaries) is a blue peanut-shaped policeman who may be the only officer working at a jail located in the city. He often fails to do his job, since he is constantly drunk and/or stoned. His state of mind prevents him from reacting appropriately to crimes that occur right in front of him. He mostly hangs out with his friend Golden Joe. Sometimes he begins to laugh uncontrollably, and anyone around him begins to laugh as well. According to the Rectangular Businessman he is "the highest marksman in the class", and "could probably hit a mite from 1000 yards in high wind". Despite this claim, Peanut Cop is usually unable to hit anything unless he is within a few inches of his intended target. He gives up his police job and becomes a fireman in Season 2.
  • Ascended Extra: Peanut Cop was originally a recurring character; later on, he makes additional appearances in Season 2, the webisode and the special "INVICTUS" as he becomes one of the main characters after joining Fitz's gang.
  • Back from the Dead: After his death by disappearing in the webisode "Enter The Sandmouse", he reappears alive in "INVICTUS".
  • Cloud Cuckoolander: Confuses blood for ice cream on one occasion.
  • The Fool: Even by the standards of someone who's completely wasted, he displays terrible judgment and is easily manipulated.
  • The Hyena: Can barely speak a sentence without laughing. The few times he doesn't are treated as O.O.C. Is Serious Business.
  • New Job as the Plot Demands: Eventually he gives up his job as a policeman to become a fireman in the Season 2 episode "Auraphull", remaining so until the finale of Season 2.
  • No Name Given: Through the show's original run. He is finally referred to as "Peanut" (one of the most common fan nicknames) in the webisode.
  • Police Are Useless: He fails to do his job all the time, often joining in on other characters' illegal antics.
  • The Stoner: Is a laid-back cop who is always stoned. When he isn't, he's lighting up a joint at the very least.

    Liquor 
https://static.tvtropes.org/pmwiki/pub/images/liquor.png
What I'm actually thinking, and please take this the wrong way as far up your hole as you can, is that your gunko schlinger is the size of a fort meizer's reticulus.
Voiced by: Matt Harrigan
Liquor is an anthropomorphic match-like being that runs the Liquor store where Fitz frequently stops at. His temperament can best be described as resigned. He seems to be Fitz's ally and is defiant to anyone of authority, such as Shark and Rectangular Businessman. Liquor also knows about the secret nature of the world. Liquor owns a liquor store whose interior is later covered in blood from Mosquitor's letter in the episode "Spider".
  • Ascended Extra: In Season 1, he was a recurring character. In Season 2 he has a much larger role, as Liquor is a very important character as part of Mouse's gang.
  • Demoted to Extra: In the special "INVICTUS", he doesn't join Mouse's gang at all and is only a background character this time, as he only makes a small cameo in a giant jar.
  • Immune to Bullets: His skin is bulletproof.
  • Meaningful Name: He is named "Liquor" because he owns a huge liquor store that sells liquor, a type of beer.
  • Only Sane Man: The only character on Fitz's side who's fully aware of the nature of the world he lives in.
  • Suspiciously Similar Substitute: His role is similar to Rhoda, due to both of them having jobs selling alcoholic beverages. After the death of Rhoda by the hands of Rectangular Businessman, Liquor fully replaces him and his role as the main bartender to assist Fitz.
  • The Bartender: Similar to Rhoda, Liquor is the bartender of his liquor store.
  • The Bus Came Back: Liquor makes a small cameo trapped in a giant jar along with a fully revived Rhoda and the Bug in the special "INVICTUS".

    Producer Man 
Voiced by: Matt Thompson
Producer Man (also known as Producer Guy and Talent Scout) is a very sociable, amusing, loud, and gregarious producer and talent scout who has a habit of walking around bent over backwards and high-fiving, and is very willing to hire actors or produce records.
  • Butt-Monkey: He is often killed in his appearances.
  • No Name Given: His name is never stated at any point in the series, with his name only revealed in outside sources, such as in a few official episode summaries from Adult Swim. Producer Man is also referred to as "Talent Scout" as seen on other sources and other websites centered on 12 oz. Mouse.
  • Out of Focus: Only appears in six episodes.
  • They Killed Kenny Again: He dies in the Episodes "Spider" and "Bowtime", but revives in "Meaty Dreamy", only for him to get killed off later in "Pre-Reckoning" by Spider in order to activate the Corn-Droid for Roostre.
  • What Happened to the Mouse?: The last time we see the Producer Man, he was killed by Spider using the Hand to control his brain. In the episode "Pre-Reckoning", his fate is currently unknown if he is dead or not. He doesn't even appear in the special "INVICTUS" (save for a small cameo in the credits).

    Eye 
https://static.tvtropes.org/pmwiki/pub/images/eyepng.png
Eye live on an eye-land in Eye-owa.
Voiced by: Nick Ingkatanuwat
A giant eyeball with legs that speaks in a calm, almost monotone pace who overemphasizes words and syllables that sound like the word "eye". He lives on an island which he claims is either Iowa (Eye-owa) or Wyoming (W-eye-oming). He also has the ability to tap dance as this is seen in "Booger Haze" & "Auraphull." It is revealed in Q109 that he's actually the eye of a human being in a simulation.
  • Demoted to Extra: The Eye as we know him is absent in the special "INVICTUS". In the special, he is found in the "real world", where he appears as a small child (though he still has an adult voice). Instead of just being one gigantic eye, he now has a human body with two eyes.
  • Eye Open: Since he is a living eyeball, his eye is always open, though his iris is capable of blinking.
  • Everyone Calls Him "Barkeep": Everyone calls him Eye because he is a giant eyeball.
  • Nice Guy: Eye is one of the nicest characters in the series, being friendly to everyone, even Shark & Rectangular Businessman (before they betrayed him)!
  • Oculothorax: The Eye is a giant eyeball with legs and a mouth.
  • Verbal Tic: Always stresses syllables that sound like "eye", as well as some that don't.

    New Guy 
https://static.tvtropes.org/pmwiki/pub/images/screenshot_2019_01_20_at_23932_pm.png
Dusk to dawn she trawls, And your will is dying (dying)
The New Guy is a strange red umbrella ghost-like creature with two sets of feet and a taste for lounge music. He lives in a warehouse, shows up from time to time and makes a flapping noise. He also seems to have an obsession with Skillet as his house is covered with pictures of the chinchilla, and has previously kidnapped him. The New Guy often plays the song Princess Cruiser by Tongo Hiti on a record player, which appears to mesmerize or otherwise mentally incapacitate those who hear it.
  • Ascended Extra: New Guy makes an additional appearance in the special "INVICTUS" as one of the main characters in the special.
  • Animate Inanimate Object: He is an anthropomorphic umbrella.
  • Back from the Dead: After being killed off at the end of Season 2, he returns alive in the special "INVICTUS".
  • Everyone Calls Him "Barkeep": Everyone calls him the New Guy because he is new around town.
  • Our Ghosts Are Different: What kind of ghost is the New Guy supposed to be? Is he an umbrella ghost?
  • Out of Focus: He didn't make that much appearances in Season 2 as he was absent for half of the season, compared to his appearances in Season 1 and "INVICTUS".
  • The Bus Came Back: After being killed off during the end of Season 2, he is one of many characters to reappear in the 12 Oz. Mouse special "INVICTUS".
  • The Voiceless: He doesn't speak at all (save for "INVICTUS" where Mike Lazzo voices a miniature version of him).

    Golden Joe 
https://static.tvtropes.org/pmwiki/pub/images/screenshot_2019_01_01_at_91024_pm.png
So tell me man, wassup? What you want with the Joe?
Voiced by: Vishal Roney
Golden Joe is a friend to Fitz, he is a loudmouthed rapping wizard who has the ability to "come and go" as he pleases through teleportation. His voice is distorted by a reverb effect and he has a single gold tooth which has a dollar sign on it. He is also a rapper who produces songs. He often risks irritating people who are close to him, especially Roostre in particular, because of his long and verbose sentences. Shark refers to him as "All disappeary and shit." Joe places a lot of importance on the ability to rhyme. He mostly hangs out with his friend Peanut Cop. By his own account, he is an excellent driver.
  • Ascended Extra: Like Peanut Cop & Roostre, he originally started as a recurring character, but eventually Joe became one of the series' main characters since he made additional appearances in Season 2, the webisode and the special in Fitz's gang.
  • Back from the Dead: After getting carried away by a hawk in the webisode "Enter The Sandmouse", he reappears alive in "INVICTUS".
  • Cartoon Creature: What kind of creature is Golden Joe anyway? An anthropomorphic green orb with mouse ears?
  • Expy: Is based on Ruby Rhod from The Fifth Element.
  • Large Ham: Golden Joe is always yelling and is very loud.
  • No Indoor Voice: He has a very loud voice, and Roostre has described him as a "a human P.A. machine".
  • Why Did It Have to Be Snakes?: Golden Joe is shown to be afraid of Shark, which can be seen in a few episodes. In "Spider", he teleports into Rhoda's bar only to flee due to Shark's presence; these feelings only got worse as Golden Joe was later captured by Shark in the last couple of episodes of the second season.

    Green-Sweatered Woman 
https://static.tvtropes.org/pmwiki/pub/images/12_oz_mouse_green_sweatered_woman_3.png
Voiced by: Melissa Warrensburg
The Green-Sweatered Woman is an annoying woman that lives in the city. Her actual name is unknown, only being referred to as the Green-Sweatered Woman (and in her cyborg form, Cyber Green-Sweatered Woman). She appears as a blonde-haired woman wearing a green blouse, shoes and a pink skirt. She speaks in an annoying, repetitive manner, often telling other characters what they're not allowed to do. This has resulted in her getting shot on at least two occasions. After being ripped in half later on, she is revived as a cyborg by Fitz and Skillet in order to be their walking arsenal, carrying many firearms from Roostre's weapons cache. In this form, she joined Fitz and Skillet in gunfights and helped kill Shark.
  • Ascended Extra: She originally started as a supporting/recurring character, but after being brought back from the dead by Fitz & Skillet, she made a few additional appearances in the rest of the series.
  • They Killed Kenny Again: The Green-Sweatered Woman has died a few times in the series such as in "Signals", where she was shot by a tank driven by Mouse & Joe. In "Rememorized", she was killed by Mouse, Skillet & Peanut Cop with their guns.
  • No Name Given: She has no actual name; however, Word of God confirms that her cyborg form is known as "Robogirl".
  • The Smurfette Principle: In Season 2, she was the only female character to join Fitz's gang.

    The Shadowy Figure 
The Shadowy Figure is a dark, looming human-type being that is seen multiple times throughout the series. His voice is unintelligible to the audience, although many of the characters in the show can understand what he is saying. He impales people with darts, and places them in a white room with a large fan. He is one of the main villains in the series, as he is seen working with the Rectangular Businessman.
  • Ambiguously Human: It's unknown if he's actually human due to the shape of his body resembling that of one; he is more a shadowy figure of a person.
  • Living Shadow: He is a human-like shadowy figure that is living, having the ability to shoot darts at people.
  • Meaningful Name: He is a creepy Shadowy Figure.
  • Silent Antagonist: He doesn't speak, when he does, it's in a creepy and unintelligible warbling computer voice.
  • The Unintelligible: His creepy voice is very unintelligible.

    Roostre 
Voiced by: Scott Luallen
Roostre, pronounced "rooster", is a human hillbilly corndog farmer near the town where Fitz lives. He plays the guitar and has a hook for a hand. In the series, Roostre talks about the mysterious "Birmingham/C. J. Muff" who left "Q109" to some characters like Fitz and Spider. He also has memories of being abducted by an indistinct figure, taken to a white room, being paralyzed by a dart to the neck, and being pushed toward a "giant, spinning fan".
  • Ascended Extra: Like Peanut Cop & Golden Joe, he originally started as a recurring character in Season 1, then became a main character in Season 2.
  • An Arm and a Leg: Roostre had his hand cut off as part of a conspiracy started by Shark and the Rectangular Businessman to keep him from interfering with their plans. He gets a hook prosthetic later on.
  • Hook Hand: He has a hook on one of his arms. His leftover hand was the Hand, but it got separated from him.
  • Prefers Going Barefoot: Is never seen wearing shoes.
  • Token Human: Of Fitz's allies, depending on whether Green-Sweatered Woman still counts as a human after joining Fitz.

    Spider 
Spider (also known as Spider-Boy) is a gigantic, seven-legged arachnid that emits insect-like squeaks, and groans. Like most spiders, he is capable of leaving large webs and shooting. However, unlike most arachnids, he can skillfully play the piano and strangely weave arrows.
  • Ascended Extra: Spider was originally a minor character in Season 1, but had a much larger role in Season 2. He also reappeared in the special "INVICTUS".
  • Big Creepy-Crawlies: The Spider is a large giant man-sized spider with 7 legs.
  • Funny Animal: Spider.
  • The Voiceless: The Spider doesn't speak, only making bug-like noises.

    Hand 
The Hand is a small, severed hand that has a mind of its own. The hand originally belonged to Roostre, but was eventually separated from him.
  • An Arm and a Leg: The hand is cut off Roostre as part of a conspiracy by Shark and the Rectangular Businessman to keep him from interfering with their plans.
  • What Happened to the Mouse?: The Hand doesn't appear in "Invictus" at all despite Roostre reappearing in the special and the entirety of the third season, however, it does appear in "Francis, Cheap & Out of Control".

    Pronto 
Pronto is a short, crudely drawn man with no torso, and an agent employed by Shark and Rectangular Businessman. His weapon of choice is a bow and arrows, and he is an expert "archerist", as Shark once called him. It is believed that he is the one responsible for the shootings of several characters, including a special effects expert outside Rhoda's bar and other random people in episode 2 "Signals" and Rhoda in episode 5 "Rememorized".

    Buzby 
Voiced by: Dana Snyder (Invictus), Paul Painter (3rd season)
Introduced in "INVICTUS", Buzby is an anthropomorphic bee serving as an exterminator that Fitz hires when he finds Spider in his house back in the real world.
  • Funny Animal: He is an anthropomorphic bumblebee with no legs.
  • Insect Gender-Bender: He has a stinger despite being male.
  • The Mole: While not truly evil, he is friends with Fitz; however, he also worked on the villains' side the whole time as he was forced to bring Fitz back to Q109 to free Shark and RBM. As another part of Shark's plan, Buzby was forced to kidnap Fitz so he can exchange his mind with Shark to enter the real world. Despite this, he is still on the hero's side, joining forces with Fitz and co. to defeat Shark and RBM at the end of special.

    Aria 
Voiced by: Mary Spender
Aria is a British scientist who operates a large laboratory with a man known as Professor Wilx, currently living in a new world named the "Lotharganin". Being the two top scientists, Aria and Wilx were once recruited by Shyd Industries to work on a confidential project, but are now stuck in a series of simulated universes, trying to reroute their way back to Outer Earth.

    Professor Wilx 
Voiced by: Ned Hastings
Professor Wilx is an African professor that has long blonde hair, appearing in the third season of the show. He works in a mysterious laboratory with Aria and lives in Lotharganin alongside her.

Minor Characters

    Woman Mouse 
Voiced by: Liz Maiellaro
Woman Mouse, also known as Lady Mouse or Fitz's Wife, is a large pink mouse that is married to Fitz. They had an unnamed baby mouse together. It is unknown how long Fitz has been married to her, or what happened to her after she was shot with a dart by the Shadowy Figure. Despite this, she was shown as a hologram inside of Shark's simulation in the episode "Bowtime".
  • Amazing Technicolor Wildlife: Similar to her husband, she is a colored mouse, and is colored pink.
  • Happily Married: To her husband, Mouse Fitzgerald before her disappearance.
  • No Name Given: Unlike her husband Fitz, she is never referred by name; instead, she is always referred to as Fitz's Wife or Woman Mouse by fans.
  • Non-Mammal Mammaries: She has human-like breasts without nipples.
  • Posthumous Character: She only appears in Fitz's flashbacks aside from Shark's simulation in "Bowtime" and her image appearing in "INVICTUS".
  • Satellite Love Interest: She has barely any characterization outside of being the main character's wife.
  • Talking Animal: Like her husband, she is a pink female anthropomorphic mouse that has the ability to talk like a human being.

    Baby Mouse 
This unnamed baby mouse is Mouse Fitzgerald's child and daughter. The baby is known as a girl, due to Fitz asking a doctor, "Is she supposed to be that small?" She is usually seen in Mouse's flashbacks, along with her mother.
  • Cute Mute: She is a baby who only communicates through cries and screeches.
  • No Name Given: Unlike her father who is named Mouse Fitzgerald and like her mother who has no name but is called Fitz's Wife or Woman Mouse by fans, she is only called Baby Mouse by fans, with no name ever mentioned.
  • Posthumous Character: The Baby Mouse only appears in Fitz's flashbacks. However, she morphs into a spider in a flashback in Bowtime.
  • The Voiceless: Fitz's daughter doesn't have a voice, she only makes crying and screeching sounds. Justified because she is a baby.
  • What Happened to the Mouse? (no pun intended): In the episode "Bowtime", in a flashback where she is transformed into a spider, this the last time we see Fitz's daughter.

    Bug 
The Bug is a small robotic bug or a group of identical bugs that work for Shark, planting surveillance cameras. A bug will often spin around and walk on walls erratically, and bugs frequently procrastinate when given assignments.
  • Big Creepy-Crawlies: The Bug is a large robotic insect who crawls around walls.
  • Silent Antagonist: The Bug never speaks; instead, it makes beeping sounds.
  • The Bus Came Back: The Bug makes a small cameo trapped in a giant jar along with a fully revived Rhoda and Liquor in "INVICTUS".

    Second Eye 
Voiced by: Nick Ingkatanuwat, Ted Murphy

The 2nd Eye is an exact clone of Eye, having every feature of the original. When he debuts in "Surgery Circus", the giant eyeball appears to be the original eye's friend. Eventually in "Enjoy The Arm", he grows an arm out of his side and grabs a shotgun, which he points at the Eye's so-called "forehead".


  • Evil Twin: He is an evil clone of the Eye.
  • Eye Open: Like the original Eye, his eye is always opened.
  • Flat Character: His character is very flat as he is only a clone of The Eye and the only trait this clone has is that he is evil.
  • Killed Off for Real: He is shot to death by Fitz, Skillet & The Cyber Green-Sweatered Woman.

    Corn-Droid 
The Corn-Droid is a robotic weaponized corndog droid and a hidden Corn-Droid possibly made by Roostre or CJ Muff. Its purpose is to destroy any threat posed to the city.
  • Killer Robot: A subversion of one. While it is a killer robot, it killed the entire population in thousands in order to save multiple human citizens from being abducted.
  • Non-Standard Character Design: Its design is more detailed than the majority of characters.
  • What Happened to the Mouse?: Its fate is currently unknown, disappearing after the nineteenth episode, although it is mentioned in the special.

    Amalockh 
Amalockh is a gigantic, many-armed monster that was summoned by Pronto using the Animal Chain, both of which he quickly devours. He resides in a giant tomb that features small pillars and turntables on the side. The tombstone lies in the graveyard.
  • Eldritch Abomination: Whatever thing Amalockh is, he is some type of monster that came out of nowhere, living in a gravestone found in the graveyard.
  • Knight of Cerebus: His return puts everyone on edge and initiates the destruction of the city towards the end of the second season.
  • Non-Standard Character Design: This character is animated with a notably higher level of detail than any other character on 12 oz. Mouse, having a design similar to some characters from Matt Maiellaro's other show, Aqua Teen Hunger Force.
  • What Happened to the Mouse?: It's unknown whatever happened to Amalockh as he is not seen in Episode 20, the webisode and INVICTUS (save for a flashback).
  • Your Size May Vary: When he first appears in the graveyard, he's slightly bigger than Pronto. Later on, he is the size of a Kaiju and rampages about the city.

    Archeus 
Archeus is a pink glowing orb that confronts Fitz in "Prolegomenon". While visually similar to C.J. Muff and the musical notes from "Booger Haze", Archeus is apparently a separate entity.

    Lee 
Voiced by: Ted Murphy
Lee is a character whose only appearance was in "Enter the Sandmouse", wanting aid from Mouse and Skillet after her gunfight with them. She talks about people who find the New Angel and "get out". That night she gave Mouse the only thing that could kill her (apparently a large silver bullet), then turned into a she-wolf.
