Terwa was a Namekian who was the former mentor of Ganbus. His strength and power greatly rivaled the strongest warriors in the universe, as he trained in multiple planets with varying gravitational pulls and strong warriors. He lived on Earth after aliens were allowed to live there in peace and harmony, and was surprised to find his pupil, Ganbus, there. After the terrible Abduc came, Terwa fought him willingly, but found himself to be subject to Abduc's power.
