Terra

The Titans spot a young blonde-haired, blue-eyed girl being chased by a giant scorpion-like creature and prepare to rescue her, only to see that the girl was merely luring the creature into a trap, where she subsequently crushes it with her tremendous earth-based abilities. She reveals her name to be Terra, and she has the geokinetic/terrakinetic ability and power to control and manipulate the earth and all of its various aspects and forms. However, she has a terrible dark secret, one that only Slade seems to know.
