An unnamed fangirl is a resident of Jump City and a known fan of teenage superheroes.
After Robin locked himself outside Titans Tower in the nude, he navigated through the bushes in an attempt to reenter the tower unseen. However, the fangirl, alongside three others, stood in front of the entrance with an "I ♡ Robin" sign, blocking his way. Upon spotting him, she and the other fangirls squealed in delight and began snapping pictures of him, causing him to run off. The fangirl joined the others in a pursuit of Robin around the island.
Sometime later, the fangirl also became a fan of Lady Legasus after she embarked on a solo career. She approached the superheroine screaming with delight and held out one of her comic books while wearing a shirt with her emblem. After Lady Legasus autographed her comic book, the fangirl ran off, giggling with delight.
