Loose Cannon

the DC hero you never know of other hero they keep showing but not him now you can meet this hero. In the absence of sunlight, Eddie Walker transforms into a super strong blue monster. Eddie Walker was a homicide detective working for a division of the Metropolis Special Crimes Unit (trained to deal with anything from meta-human crime to alien invaders), led by Maggie Sawyer. 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. Suffering from deep depression, he considered suicide, but Eddie was luckily contacted by Maggie before he could bring himself to carry it out. Maggie asked Eddie to investigate a slew of murders in a homeless district. Unbeknownst to anyone, these murders were actually the work of alien parasites who'd come to Earth to drain the spinal fluids of humans. Eddie ended up being attacked by two of these parasites, but instead of dying, the crippled detective ended up inadvertantly gaining the ability to transform himself into a superhuman giant. With his new powers, Eddie teamed-up with the Eradicator (who was filling in for Superman at the time), together they were able to drive the aliens out of Metropolis. With a new lust for life, Eddie dubbed himself "Loose Cannon," and took part in ridding the world of these alien parasites for good.
