Diablo's Mutants

Neptis doesn't remember anything from his past. Now he's in a top secret lab where genetic mutations happen. Kids and teens are being tested on but all of them die. Neptis goes through the mutation and survives. He becomes invincible. He then meets two others that have survived. Leuko with enhanced strength and Hayze with multiple mutations. But when Neptis over hears the boss of the lab, Diablo, talking about how he wants to use the kids for evil, Neptis knows they need to escape.
