Ghetsis is one of the Seven Sages of Plasma Gang. He contacted Colress via holographic communication while he was working at the Sangi Town observatory lab to find out how he was progressing. After hearing that Looker was about to intervene, he suggested that they sent out Tunbear to fight them and wished him luck during the fight. Looker thought that Colress was Ghetsis until he was told otherwise.
