Warren Rocko is a member of the Fairy Tail Guild who uses telepathy, a magic that allows one to converse mind-to-mind. In battle, it's possible for him to read his opponent's mind. Although he may not look it, he is classified as one of the more powerful wizards in the guild, and he has gone on a huge number of jobs alone. His fear of heights causes him many problems. At one point he took a girl on a date, but as they were crossing a bridge, his mental shouts of "Help, save me!!! I'm scared!!!" were heard by everyone in the town. His design is similar to the character Branch from Rave Master.
