Terra started out as a shy and quiet girl but was immediately liked by everybody. Terra is quite insecure. She wishes to do good with her powers, and her determination to gain control of them is evident, but her lack of existent control usually proves them to be a danger instead of a benefit, thus making her reluctant to use them. Before Terra became a Titan
, this lack was very evident and surfaced through her weak control over her powers and emotions. She had tried to put up a front of confidence, but was actually extremely afraid of people finding out how unstable she was.
Among the Titans, she is closest to Beast Boy
. He feels he knows the most about her and so is the most understanding towards her. She told Beast Boy she couldn't control her powers and Beast Boy still welcomed her. At first, she gets along well with all the Titans except Raven
. Later, Raven develops a respect for Terra. After her return, Terra seemed to command much, much more control over her incredible earth-controlling and manipulating powers and capabilities. Beast Boy wanted to go on a date with Terra and she gladly accepted. Beast Boy and Terra are both happy and fun-loving.
However, Terra is a bit naive. Slade was able to trick Terra into becoming his apprentice and annihalating the Teen Titans. She felt betrayed when it appeared that Beast Boy shared her secret with the team (even though Robin
actually realized it on his own). Feeling betrayed and alone, Terra turned to Slade
, who trained her to fully control her abilities. Terra returned to the Titans and joined the team - but was secretly working with Slade to destroy the Titans from within. Despite her mission, Terra began to doubt her loyalties; Just as romance with Beast Boy blossomed, Terra was exposed as a traitor. Hardened and isolated, friendless and emotionally hurt, Terra turned to the only one who would accept her, Slade
, and shortly the two united to launch their plans in full motion. Caught off guard and still holding some affection for their former friend and teammate, the Titans were nearly defeated in the first round, with Terra brutally showing far less mercy and restraint, and in the second, due to reinforcements sent by Slade under her control, Robin was forced to make a retreat back to Titans Tower, knowing this battle could not be won.
When the other Titans lost faith in terra, Beast boy knew there was still good left in her because he knew her better than anybody. Beast Boy pointed out that they never gave up on robin when he was Slade's apprentice. Robin battled Terra for a second chance but she claimed she's not a "not some sad little girl" expressing a vast and deep-rooted anger that was not entirely directed towards him. This may be a clue to her earlier life. Terra especially hated Raven possibly over Beast Boy's affections. Never truly losing faith in Terra, Beast Boy stepped in between her and Slade and finally made her realize the error of her ways. Events were eventually set in motion leaving the city in danger from an erupting volcano. In a final act of friendship, she ultimately sacrificed herself to save the city. Now merged with the Earth she controlled and manipulated, the Titans searched for a way to restore her.
