Prypiatosian-B

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

Physiology
According to Dwayne McDuffie, Prypiatosian-Bs are physical humanoid beings that constantly emit a pure radioactive energy around their bodies. They usually wear dark-colored oven-like containment suits to contain their immense irradiation.

Although Prypiatosian-Bs are traditionally red, orange Prypiatosian-Bs also exist.

Powers/Abilities
The energy that Prypiatosian-Bs radiate enables them to generate intense heat, allowing them to melt down solid metal and rock by merely touching it.

Prypiatosian-Bs are capable of firing radioactive energy beams from the grills of their containment suits, which can corrode metallic objects.

Prypiatosian-Bs can channel heat through the ground, resulting in a massive geyser of lava.

The containment suits worn by Pryppiatosian-Bs are fireproof, being able to resist a Methanosian's fire attacks. Overall, these containment suits are virtually indestructible against most attacks, making them extremely durable.

While not wearing their containment suits, a Prypiatosian-B's powers are greatly increased. They also gain the abilities of flight and phasing through objects.

Prypiatosian-Bs can make themselves glow like a light bulb, which is bright enough to weaken Ectonurites.

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 comes at the cost of greatly reducing a Prypiatosian-B's powers. As such, they are unable to fly while wearing these suits.

A Prypiatosian-B's vision is limited because of the shape of their containment suits' helmets, and they can be blinded even further by adhesives.

Behavior
Prypiatosian-Bs speak using a Russian accent.

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, the Ben 10 Franklin version of Benjamin Franklin, and Mad Ben.

Etymology
Prypiatosian-B is derived from Prypiat, a Ukrainian city where the Chernobyl disaster occurred in 1986.
