Terra likes to talk to many people, even if they do not particularly like him. He is very easily offended, which causes many of the other Nays to dislike him. Ralphie and his friends still treat him with respect however. Terra was trained as a martial artist by the master Earl Gray, although compared to the others, he is fairly weak. After a particularly traumatizing event, he begins to act much more serious, somber, and angry.
