Martinex (Marvel Comics)

Martinex T'Naga is a Pluvian from an alternate reality in which present day is in the 31st century and mankind has colonized several other planets in the solar system, including Pluto.

Powers
Pluvian physiology: As a Pluvian, Martinex is descended from the original human colonists of Pluto who were genetically-engineered to survive on that planet.
 * Silicon-based life form: Martinex is composed of silicon crystal instead of carbon matter. This makes him stronger and more durable than a normal human. However, when injured, his body heals slower than a human.
 * Enhanced vision: Martinex can adapt his eyes to see in blinding light or near-total darkness.
 * Vacuum survival
 * Temperature resistance: Martinex can withstand a greater range of temperatures than a normal human.
 * Thermokinesis: Martinex's physiology can further improve his resistance to temperature extremes by siphoning excess heat from the environment to warm up or venting his own body heat to cool down. Martinex can also focus this effect offensively to project thermal beams of heat or cold.
