"Master Chief: The Finale" is the ninth and tenth episodes of season 1 and the first season finale.
After a short "previously" segment, Master Chief mentions he fled before meeting the true leader, and he and the Arbiter triangulate the location of the villain's base and learn it is in the middle of Florida. The Arbiter challenges L. Ron Hubbard while Master Chief learns Jack Thompson has cloned himself to take over Congress and fights the clones. Mario, Link, and Samus are recruited again to distract CATS. The Arbiter is successful in stabbing Hubbard to death. Master Chief flees from the Thompson clones. CATS defeats Mario, Link, and Samus. The Arbiter is confronted and captured by Tom Cruise, the new leader of Scientology.
In part 2, Master Chief confronts CATS and duels him. Their duel is cut short when the mysterious leader announces CATS has outlived his usefulness and shoots him to death. A montage shows the Arbiter, Mario, Link, and Samus held captive by Tom Cruise and Jack Thompson. The mysterious leader reveals himself to Master Chief as none other than the King, mascot of Burger King.
