As children growing up in Australia, Selinda Flinders and her brother Baran received nothing but mockery as their unique abilities developed. She could transmute elements, while he exhibited terrifying strength. When the frustrated siblings used their powers against the local children, enraged and fearful adults tried to drive Selinda and Baran’s entire family out of town. As a compromise, the children’s father brought his two children to the renowned Markovian scientist Dr. Helga Jace. Jace helped the siblings understand and expand their powers, while trying to instill a sense of morality in the two teenagers.
Nevertheless, Selinda and Baran used their powers for personal gain, establishing criminal records as Shimmer and Mammoth. Later, they answered an ad placed by the super-criminal Dr. Light and joined his new criminal organization, the Fearsome Five.

Five by Five
The Fearsome Five’s first case brought them into conflict with the Teen Titans, and this was the first time Shimmer and Mammoth met defeat and imprisonment. The inseparable brother and sister were later freed, and sought revenge against the Titans from time to time.
Selinda and Baran eventually found peace in a Tibetan monastery, where they renounced their life of crime. But the Flinders’ newfound peace was soon destroyed by the arrival of Psimon, who sought revenge on his former teammates for abandoning him. Psimon exacted his revenge in a vicious two-pronged attack. First, he used his extraordinary psionic powers to drive a spear through Baran’s head. Next, he transformed Selinda into glass and shattered her into thousands of tiny shards.
Baran miraculously survived the attack and resumed his life of crime, but was devastated at the loss of his sister.

Sometime later, Dr. Sivana organized a revamped Fearsome Five comprised of Psimon, Jinx, Gizmo, and Mammoth. Sivana enlisted Mammoth with the promise of restoring his long-dead sister, Shimmer. Psimon was able to assemble the remains of Shimmer’s shattered crystalline form, as Dr. Sivana’s super-science successfully restored her to life. Upon awakening, Selinda wasted no time returning to her criminal ways with her fraternal partner-in-crime. The newly formed group was hired to initiate a corporate espionage plot against Lexcorp, but their efforts were undone by Nightwing’s Outsiders team.
Since then, Shimmer and Mammoth have remained with the Fearsome Five although its membership is constantly changing. Plagued by personal agendas and constant in-fighting, the evil organization’s biggest obstacles can often be found within its own ranks!
