The Pyrosapiens are humanoid aliens which radiate pure, red/orange energy around their bodies. The Females are shown to have excessive energy on their heads in the form of hair.
The energy Pyrosapiens radiate enables them to generate intense heat, and melt through solid metal and rock by merely touching it. They are capable of firing highly radioactive energy beams which can corrode and melt metallic objects. They can channel heat through the ground, resulting in a massive geyser of lava.
Pyrosapiens can fly at high speeds.
A Pyrosapien's power is greatly reduced whilst they are in containment suit.
Pyrosapiens constantly give off radiation, making them dangerous to teammates. Which is why they must wear the suits.
Pyrosapiens feed by absorbing energy and the more they absorb, the bigger and stronger they become.
Pyrosapiens have also been known to eat Uranium as well.
