Kole is one of the many Honorary Titans from the show Teen Titans and comics. She has the power to turn her body to crystal and can be used by her caveman assistant Gnarrk as a sword, shield, or even a boomerang. In the comics she dies.
Kole is a girl who fled the surface world from unscrupulous people who wanted to abuse her crystal powers for their own personal doom. Under circumstances yet to be revealed, she found her way into a subterranean prehistoric world under the frozen Arctic, where she met the neanderthal Gnarrk who would become her friend.
She lived there peacefully until the Teen Titans literally dropped by following a confrontation with Dr. Light. Dr. Light had created a levitation device which could feed the light of the arctic auroras into his armor and body, making himself even more formidable, but the synthetic diamond he used as a focusing element had proven inadequate. Upon seeing Kole's powers in action, Dr. Light attempted to use her as a new focusing element, but luckily she was saved by Gnarrk and the Teen Titans, who subsequently made her an Honorary Titan member.
At some earlier point she bothered the Titans with testing the communicators which connected the Titans around the world, but not long after she and Gnarrk fought Billy Numerous and Gizmo acting under commands from the Brotherhood of Evil. She and Gnarrk fought them off and later joined Cyborg in aiding the other heroes in the final battle against the Brotherhood. Afterwords she was seen at Titans Tower beside Gnarrk, socializing with the other Titans, and subsequently joined the Titans to battle Dr. Light, who had just robbed a bank</p>
