He is the partner of Kabal in the New York City SWAT organization. Both were chosen to be part of the nine warriors to fight Shao Kahn in the Battle for Earthrealm, though they do not even know it. During the invasion, Stryker and Kabal are spotting any problems from the rooftop of a high building, when they suddenly spot Reptile sticking to the building's outside. They draw their weapons and fire at him, but Reptile manages to dodge them all and jumps onto the roof. While Kabal reloads his pistol, Reptile incapacitates Kabal by spitting his poisonous saliva at him, and grabs Stryker's pistol with his tongue. Stryker challenges him and manages to win, then helps the wounded Kabal. They both head to the ground floor, where they look behind a window and see a large beast.
