Cynthia Aurora "Cindy" Vortex is Jimmy's arch-rival and hinted love interest. While she is mostly antagonistic towards some of the main characters, she is still considered one of the main characters as she helps them out on their adventures many times.
Cindy is basically the anti-dumb blonde role. She is a very prideful, intelligent, and competitive character, and she was shown with these personality traits throughout the series. While she has a crush on Jimmy, she plays an aggressive, bully role, and pretends to dislike Jimmy to hide her true feelings.
Cindy appears as an NPC in Nicktoons Unite! Cindy only is found in Jimmy's lab to talk to but further she doesn't has any impact on the story.
