*Lexi Bunny is the tritagonist of Loonatics Unleashed and the only female member and Co-Leader of the Loonatics. She is an anthropomorphic rabbit. She is the descendant of Lola Bunny.

Before gaining her powers, Lexi was a student at Acmetropolis University who tried to join the school's cheerleading squad. The captain, afraid she was too good, did not accept her. Lexi enjoys playing video games in her spare time and is implied to be the best of the team at it, and wears a pink uniform. She leads the group alongside Ace Bunny and Danger Duck (on occasion).

Lexi Bunny is the second-in-command of the Loonatics. Before getting her powers, Lexi was a student at Acmetropolis University who tried to join the school's cheerleading squad. The captain, afraid she would be overshadowed in terms of skill, did not accept her. Nevertheless, Lexi is the most agile and acrobatic member of the team.

As a member of the Loonatics, Lexi is the team's eavesdropper. Her powers, if not equal to, are almost as powerful as Ace's.

Lexi occasionally expresses concern about her looks, the first time being in the pilot episode "Loonatics on Ice" when Zadavia tells them about the freeze Lexi mutters about how wearing a sweater would make her look chubby. Another example is in "Stop the World, I Want to Get Off" when she asked if Tech could find a way of reverting their weight to normal without making them look bloated.

A further example is in The World is My Circus after being mutated by the DNA scrambler of Ringmaster and Otto she says that they can't keep fighting and the Pepe Le Pew look is not her. This is an ironic statement as she along with all the other Loonatics would eventually encounter Pierre Le Pew (the evil human parody of Pepe Le Pew) who observed her placing a Pterosaur back into the Acmetropolis Zoo (it was implied that he released the animals to be able to recruit Slam to his illegal fights arena) and Pierre attempted to flirt with/hit on her by complimenting her looks. Lexi however was predictably repulsed by Pierre's stench and creepy mannerisms.

She wears a black suit with pink schemes, a green ribbon tied up her ears, light green eyes, and a golden blonde hair and eyebrows.

Whenever she wasn't wearing a bodysuit, her fur is ivory and white without any visible chest pattern unlike Lola bunny, light blue eyes, and aery light blonde hair.*
