What happens to terra in teen titan?

Answer 1

These may be spoilers, warning you now. IT IS ALSO A VERY LONG SUMMARY D:

After Terra originally flees Titans Tower after assuming Beast Boy told the other Titans about her inability to control her powers, she was secretly training with Slade. When she comes back she acts as a "mole", and helps Slade ransack Titan's tower. However, she takes Beast Boy to an amusement park while the Sladebots invade. When Beast Boy finds out Terra betrayed them he refuses her friendship, and she fully gives herself to Slade. She then puts on a suit that genetically attaches to her, giving Slade full control. She attempts to wipe out the Titans one by one, but fails. Plasmus, Overload, and Cinderblock attack the Titans while she (Terra) flees, back to Slade, but Beast Boy follows her. She then begs for him to kill her, because she doesn't want to fight anymore. The other Titans arrive, and Terra realizes she has control over her life and defeats Slade, throwing him into the volcano. However, the volcano is going to erupt, so she sacrifices herself to save the city. By doing this she turns to stone, until the fifth season.

In the last episode of the fifth season, the Teen Titans return to Jump City after the fall of the Brotherhood of Evil. During a fight with some shapeshifting monster... thing... Beast Boy swears he sees Terra and begins searching for her. The other Titans think it's impossible she was reversed from her stone state.

He finds a girl at the High School and tries to make her remember she is Terra, but she insists he "Has the wrong girl". In the end, she tells Beast Boy he is the Titan and he should move on with his life. She also says "Things Change" and goes back to class. There's been much debate, but most people assume this is Terra brought back to a human state from a stone state when Raven saved the world from Trigon (remember, everyone but the Titans was turned to stone during that fight).

Beast Boy moves on, and Terra lives on as a normal high school student.

Answer 2

She was stopping a volcano she created and wasn't seen for some time then reappeared and she "forgot" who Beastboy was!
