Terra

Terra's the 6th member of the Teen Titans team. she was once Slade's 2nd apprentice right after Robin was his 1st apprentice, but they both got out of it, but Terra sacrificed herself into a stone statue, then got revived, along with other people who were turned stone solid (due to Trigon's pure evil magic powers), then went undercover to hide her true super powers as a school girl. She discovered her geo-kinetic powers returning to her during volley-ball in gym class, and she returned to reunite with the entire team. She's voiced by Ashley Johnson in the entire franchise.
