The giant bacteria were monstrous purple germ creatures created by Dr. Viper when he mutated his fellow evildoer Morbulus. Following Morbulus’ horrific mutation, he was used by Dr. Viper in his attempt to raid Megakat Biochemical Labs. The practically indestructible monster would divide into more of itself whenever hit with conventional weaponry, and because Morbulus literally had eyes in the back of his head, the original monster had four eyes. Whenever the giant bacteria split, the eyes would be divided up among the individual monsters. In all, there ended up being three monsters, one with two eyes and two with one eye each.
