Edward "Eddie" Walker was a homicide detective working for a division of the Metropolis Special Crimes Unit. Walker became known as the department's volatile "Loose Cannon" for his reckless attitude. Tragedy struck when Eddie was crippled in a car accident, and he was given a desk job.

Eddie ended up attacked by Lissik, but instead of dying, he inadvertently has the ability to transform into a superhuman abilities and also allowing him to walk again. With his new powers, Eddie teamed-up with the Eradicator against Lissik and two other parasites, Glonth and Pritor, and drive the aliens out of Metropolis.
