Kole Weathers (New Earth)

Professor Abel Weathers, paranoid of an impending nuclear holocaust, was attempting to find a way for humanity to survive the fallout through forced evolution. One of the test subjects in his experiments was his sixteen-year-old daughter, Kole, whom he grafted with Promethium. However, instead of evolving, she found herself with the ability to create and control silicon crystal.
Kole was then kidnapped by the mad sun Titaness, Thia. For two years, Thia forced Kole to use her powers to construct a crystal prison in which Thia can hold important prisoners. Thia eventually came into conflict with the Teen Titans... which ultimately lead to the death of the goddess and Kole winning her freedom. Lilith, a member of the Titans who has the power to tell the future, sensed the "dark clouds of destruction" around Kole and warned her that she would face a "grim future" should she return to Earth and invited her to remain in Mount Olympus. Kole declined, electing to reclaim her life on Earth.

Now back on earth, Kole tried to reunite with her parents, only to find that her father's experiments had produced a house full of crystalline and insectoid monstrosities. When the Titans came to confront him, he had them captured and attempted to subject them with the same experiments. Kole helped them to escape, and in the ensuing conflict, Abel and his wife Marilyn transformed themselves into insects and caused the lab to self-destruct. Having nowhere else to go, Kole chose to go with the Titans to New York City, though she never officially joined (this fact seems to be contradicted in other later sources such as The Secret Origins of the Teen Titans in which Dick Grayson lamented how Kole was a "Titan for such a short time").

Kole was apparently killed during the Crisis on Infinite Earths by the Anti-Monitor's shadow demons while trying to protect Earth-Two's Robin and the Huntress. Note: The Crisis of Infinite Earths rewrote the origins of Donna Troy, in which Thia and her fellow Titans of Myth played a major role, which means Thia never kidnapped Kole and thus how Kole met the Titans has been nullified. There has yet to be an updated origin for Kole.

After her seeming death, Kole mysteriously resurfaced a few years later, where she assisted the Team Titans against a pack of vampires. Her powers had somehow been upgraded with the ability to teleport from place to place at will and sense events happening miles away. She also hinted that she isn't anything "alive". After helping the Team Titans in several battles, Kole vanished again. It was later suggested that this was not in fact the real Kole, but a puppet created by Monarch. However, when an organization called The 1000 did a data search on all the Titans, living and dead, Kole's file read "Data Inconclusive", which added some doubt to her final fate.

Kole's death was confirmed however, only a few years later. The teen successor to the line of Brother Blood created a team of zombie combatants made up of the resurrected deceased members of the Titans. Among those within Blood's ranks was Kole. When Blood's control over these undead Titans was broken by Kid Eternity (whose powers Blood had tapped to bring them "back to life"), they seemed to simultaneously decompose and vanish as they were returned to the afterlife.

Furthermore, Kole has a statue in the "hall of fallen Titans" at Titans Tower, alongside the original Hawk and Dove, the original Aquagirl and others.

Kole makes a brief cameo in Teen Titans #68 when Kid Eternity summons her spirit to use her crystals to open the door to the Hall of Records in Hell to examine the terms of Kid Devil's pact with Neron.
