Captain Liberty is one of the main characters in The Tick live action show, played by Liz Vassey. She is apparently a parody of mainstream superheroes like Captain America and Wonder Woman, much like American Maid from the animated series. She is employed by an unnamed government agency and frequently teams up with The Tick, Batmanuel, and Arthur to fight crime. Due to the show's budget constraints, she is rarely seen actually fighting crime, much more frequently seen after the fight is over or in the super hero bar the four spend much of their time together in.
She is also in an on again off again relationship with Batmanuel whom she disdains but can't seem to stop having sex with; Batmanuel often addresses her as "Janet". Her attempt to date a non-super man failed once he discovered her super hero identity. Her brief affair with a celebrity hero called the Immortal resulted in his untimely and ironic death, after which she found out she was not his first conquest.
