Biography
Years ago, Sobek arrived in orbit of what he believed to be an Ancient Treasure planet. He sent his Jaffa down to the surface to breech the central temple. When they couldn't find a way in, Sobek used his ship's main weapon and collapsed it. This attack activated Kotah, who used his giant sword to destroy Sobek's ship.

Since his activation, Kotah protected the remains of the Ancient temple, as well as guarded the Stargate. He would kill anyone who attempted to leave the planet.
