Reptile has always loyally served as Shang Tsung's protector - while maintaining a very low profile in the first tournament he discovered Tsung's plot to force the remaining members of his near extinct race into slavery under Shao Kahn's rule. Reptile then devises a plan of his own. He enters the Outworld tournament, defeats Shao Kahn and turns against Shang Tsung, ending his master's scheme. Now his race can live on in their own peaceful existence.
