12 oz mouse Wiki

Aria is a major protagonist in 12 Oz. Mouse, introduced in the third season of the series. She 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 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.

She is voiced by British singer/songwriter Mary Spender, who collaborated alongside Maiellaro on Freebird Your Mind, a song heard during the closing credits of "Francis, Cheap & Out of Control." Due to Mary's love for music, this aspect of her life was incorporated into the character, with Aria often seen playing an acoustic guitar and singing.


Unlike most 12 Oz. Mouse characters, Aria is animated with a notably higher level of quality, having more detailed features. Her facial features consist of brunette hair, brown eyes, a small nose and ears, and red lips. Along with this, she wears a white bodysuit, with colour-changing panels around her legs, arms, and chest that often change colours to match her emotions.


Alliances & Friendships[]

As mentioned before, Aria has formed an alliance with another top scientist named, Professor Wilx. She has also befriended Mouse Fitzgerald, a character who was once associated with Shyd Industries' simulation project. Due to his former involvement, Aria assists Fitz in regaining his memory, as he previously designed the layout for the worlds, and only knows the way to escape them.


Aria despises Shyd Industries' malicious plan to trap people within these simulations and expresses hatred with anyone associated with the company such as Industry Man and Sirus. Knowing this, it can be assumed that she dislikes Shark, the Rectangular Businessman, and other antagonists.

Episode appearances[]
