Jonas Graymalkin

Graymalkin's mutant powers are related to light exposure; the darker it is, the greater his powers become since the absence of light triggers his powers. His powers strengthen with a lack of light. Hank McCoy stated that he was unpowered in the presence of light. Graymalkin has demonstrated the following powers:
 * Superhuman strength
 * Near invulnerability
 * Enhanced agility
 * Longevity or immortality: He is able to survive without food or water indefinitely. In complete darkness, he was able to survive 200 years with neither food nor water.
 * Night vision: He is able to see clearly in total darkness.
