Shark (or "The Shark") is the Main Villain/Antagonist of 12 Oz. Mouse along with The Rectangular Businessman & Clock. Initially seen as the president of an employment company (and possibly of the show's setting), he eventually develops into one of the main antagonist alongside the Rectangular Businessman, and is later to be involved in a large conspiracy against Fitz is portrayed as an intimidating, yet soft-spoken creature who has a short tolerance for those around him. While he constantly threatens with violence, he 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.


Shark was originally voiced by Adam Reed and is one of two characters who do not use an original design[1], the other being Skillet. In the 12 Oz. Mouse special INVICTUS, when Shark is dressed as Fitz's Therapist, he has a female voice & is voiced by Rita Morales. From the third season's first episode Francis, Cheap & Out of Control, he is voiced by creator Matt Maiellaro, during the rest of the third season Shark's current voice actor is Ned Hastings & replaces his original voice actor Adam Reed due to him being unavailable at the time of the third season's production.

Appearance[edit | edit source]

Shark is a non-anthropomorphic Blue Shark, the lower part of his body is white like a great white Shark, he has a mouth with sharp teeth, a nostril, he has five gills on his body, has blue fins as part of his body, & a long tail.

 Relationships[edit | edit source]

Alliances & Friendships[edit | edit source]

Despite befriending the Rectangular Businessman, they are regularly at each other's throats, critiquing one another's actions. Shark shares a slight amount of hatred for the square-being, but having to work together, decides to put up with the businessman's attitude. His infantry of robotic insects is quite ignorant, which usually causes Shark to become miffed. Other affiliates include the clock and skilled archer, Pronto. While Shark doesn't interact much with the unnamed clock, he has had several conversations with Pronto, often concluding in Shark regarding the latter as having poor abilities.

Enemies[edit | edit source]

Similarly to the Rectangular Businessman, Shark decides to insult others rather than make peace with them. While not as snobby, he shares several traits of the aforementioned square creature. While Shark doesn't outright hate certain characters, he has a slight distaste for most. He dislikes Rhoda, and due to the latter knowing too much about his conspiracy, orders to have him killed. As Shark doesn't relatively despise Golden Joe and the Eye, he is often annoyed by both character's personas.
