Crash

Crash was a 24 year old male working in a laboratory, he had three kids and a loving wife until a tragic accident killed him at work, he struggled to put on his gas mask but it was broken, so the gas got in his skin and eyes melting it to a black rotten shell of previous skin. this same accident also gave humans superpowers wow. Crash is now a ghost haunting the laboratory trying to kill anyone with superpowers because he believes humans shouldn't have them. You are whatever you want just make the plot have a bit of sense.
