Shimmer (also known as Selinda Flinders) is a fictional villain from DC Comics, created by George Perez and Marv Wolfman. She first appeared in New Teen Titans #3 (January 1980) as one of the founding members of the Fearsome Five after answering an advert in the Underworld Star placed by Doctor Light, who was looking to establish his own villain team, and so became enemy of the Teen Titans, Superman, and the Outsiders. She is Australian by birth, and has a brother named Baran (aka Mammoth), also a founding member of the Fearsome Five.
