Prypiatosian-B

Prypiatosian-Bs are a race of radioactive aliens from the planet Prypiatos in the Andromeda Galaxy.

Appearance
Prypiatosian-Bs are humanoid aliens which radiate red radioactive energy around their bodies.

Abilities
The energy Prypiatosian-Bs radiate enables them to generate intense heat and melt solid metal and rock by merely touching it. They are also capable of firing radioactive energy beams which can corrode metallic objects. They can channel heat through the ground, resulting in a massive geyser of lava.

Weaknesses
Prypiatosian-Bs constantly give off radiation, making them dangerous to allies. This weakness can be remedied by putting them in a containment suit, but this also greatly reduces their power.

Technology
While considered a highly advanced civilization at one point, they at least have atomic weaponry as this was how they brought about the end of their once prosperous civilization and left their planet's surface highly irradiated.

Omnitrix Transformation
The Omnitrix's Prypiatosian-B representative is named NRG, who first appeared in the Ultimate Alien episode "The Forge of Creation". He was originally unlocked in "Too Hot to Handle" after the Ultimatrix scanned P'andor. NRG solely appears in Ultimate Alien and Omniverse.

NRG has also been used by Albedo and Mad Ben.
