Shimmer

Shimmer is a member of the Cult of the Kobra.

History
Shimmer is Kobra's right hand. When the Kobra Venom was first produced, Shimmer injected, Mammoth, with one ampule of the drug. He was permanently transformed into a super strong monstrosity. She seems to be adept in martial arts, as Kobra confidently ordered her to one on one combat with Robin on July 22. She also seems to have mechanical skills as she repaired Sportsmaster's sabotaged helicopter.

She was subsequently sent to Belle Reve Penitentiary.

Background in other media

 * In the comics, Shimmer has the power of transmutation, the ability to turn one object into another. Whether she has this, or any other, power, in Young Justice has yet to be revealed.
