The Alien Pilot and the Alien Co-Pilot are the commanders of the U.F.O. that abducts the player. They appear at the end of the quest Alien Abduction. They attack the player on sight as he reaches the cockpit. When the Alien Pilot reaches a low amount of HP, he runs away leaving his hat behind, causing the Alien Cockpilot to put on the hat and activate an attack named 'So Be It'. When they are defeated, the U.F.O. loses control and crashes to Earth, causing the green goo to leak out of it and into the drains of South Park.
