Grrrl

Grrrl is a Human cross-species dresser who has been seen dressing up as an Omicronian. She first saw Lrrr, ruler of the planet Omicron Persei 8, at Comic-Con 3010, where she was first convinced that he was another nerd wearing a costume. She later met him in The Hip Joint. Then, she began developing an attraction to him, even after realizing he was an actual Omicronian. Grrrl also said she wanted to have his Popplers.

Character Description
She seems to have some kind of lust for alien monsters, as, once Lrrr "dumped her", she immediately turned to Dr. Zoidberg, a Decapodian. However, it's also possible she thought he was a cross-species dresser too, given that she also has a Decapodian costume.

Trivia

 * Grrrl is a pun on Lrrr and girl. It is probably not her real name.
