Microbe (Marvel Comics)

Zachary Smith, Jr., also known as Microbe, is a mutant son of a medical researcher who once thought he discovered a method of curing incurable diseases. However, it was later revealed that Microbe had unknowingly used his emerging mutant powers to influence microbes to do what his father wanted them to do. Disgraced, Microbe's father disowned him and left him heartbroken and alone until he was recruited by the New Warriors.

Powers
Microbial communication/control: Microbe is a mutant who possesses the ability to communicate with microorganisms in his vicinity. He anthropomorphisizes the sensations he receives from these microorganisms and believes the germs are actually talking to him. He can use this power to sense the presence of humans around him by the bacteria they carry with them at all times and recognize the difference between humans and androids or shape-shifters attempting to pass as another person. His ability is sensitive enough to tell him how long it had been since a person had last bathed and brushed their teeth, and he can also tell how long an animal had been dead.

Microbe can exacerbate the effects of different bacteria on people, causing them to become sick or nauseated to varying degrees, or do the opposite and sterilize wounds by keeping microorganisms away from open and exposed injuries. With the proper microorganisms present, he can fix a flat tire, cause metals to rust, prevent milk from spoiling, manipulate flesh-eating bacteria to consume cancerous cells, and other specific effects.
