Project 153

Project 153 is a bio-engineered soldier created by Systems Corp. 153 is the predecessor model to Project 154. He is a pilot model, designed to operate vehicles and equipment too complex or hazardous for average human pilots. He always thinks ahead and is entirely aware of his surroundings. He also thinks of himself to be the superior bio-weapon, until his first battle with Project 154, who singlehandedly takes out his battle walker.

Biography
It is unknown how Project 153 came to be, but it is obvious that he chose not to insurgent against Systems Corp., unlike 154.

Thing-Thing 3
153 makes his debut appearance in Thing-Thing 3 (ironically, "153 Thing-Thing 3"), as an anonymous guide. He eventually leads Project 154, his successor, to the floor above Vahl Dreig's lair. 153, with the help of Systems Corp. mercenaries, try to take on 154 but are unsuccessful in this endeavor, with 153's bipedal walker obliterated. As Project 153 flees upon defeat, he collapses the floor beneath Project 154, leading him into the lair of Vahl Dreig.

Thing-Thing 4
Project 153 reappears in Thing-Thing 4, and confronts Project 154 again, in a Systems Corp. skyscraper. Project 154 flees by jumping out the window and jacking a sports car, but Project 153 gives chase in an attack helicopter. Project 154, unfazed, shoots down the helicopter with a large machine gun, and Project 153 is presumed dead.
