He was a government agent who went on a mission that would change his life forever. X-Eye held him hostage and put him in a fusing machine against his will. Now Chris Walker was half-human and half-mountain lion. X-Eye soon named Chris Walker Spy Lion and Spy Lion was still able to complete his mission. Spy Lion then went into hiding in the forest outside his home city because he thought he had become a monster. But over time, Spy Lion soon became a superhero and began his long association with fighting crime. Sadly, Spy Lion was killed by Exclamation Point and his death stunned the nation. But secretly, X-Eye had cloned Spy Lion and that may mean he may return once more.
