He was sent back in Egypt, to find a Spaceship, hidden by Sirians on planet Titan, and go to planet Sirius to assassinate Mental, to prevent the invasion on Earth, and its annihilation. Unfortunately, a Crate Bus full of Croteam Heads crashed into SSS Centerprice, the spaceship that lead to Sirius. Then he took the Holy Grail and activated the Back-Up Spaceship. Then the Wizards summoned him, and gave him another quest. He finally went to Sirius, but Mental escaped when he arrived at the Mental Institution and destroyed it.
