The character sheet for the [adult swim] cartoon, 12 oz. Mouse.
Major Characters
- Voiced by: Matt Maiellaro, Seth Green (Invictus)
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.
- 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.
- Voiced by: Adam Reed (originally), Rita Morales (briefly), Matt Maiellaro (briefly), Ned Hastings (currently)
- 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.
- Voiced by: Kurt Socclich
- 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.

- Gentleman Snarker: He enjoys the finer things, and is petty AF.
- Screw the Rules, I Have Money!: His modus operandi.

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.

- Cloud Cuckoolander: Confuses blood for ice cream on one occasion.

- Only Sane Man: The only character on Fitz's side who's fully aware of the nature of the world he lives in.

- 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".
