Prypiatosian-Bs are a race of aliens from the planet Prypiatos[merch 1] in the Andromeda Galaxy.


Prypiatosian-Bs are physical humanoid aliens that radiate pure, red, radioactive energy around their bodies.[DM 1]


Prypiatos was once the marvel of the Andromeda Galaxy, with mega-cities filling entire continents with hundreds of thousands of glittering structures that truly seemed to scrape the sky, but an atomic war put an end to that. In the aftermath, some of the planet's denizens managed to escape underground to avoid the nuclear fallout. They came to be known as the Prypiatosian-As, and eventually established new subterranean cities of their own, lead-lined for their own protection from the hazardously irradiated world that had once been their home. Others, now known as the Prypiatosian-Bs, stayed above ground, scavenging in the ruins of their once great civilization, where they were mutated into the highly radioactive beings from which P'andor, and subsequently NRG, are descended.[merch 1]


Prypiatosian-Bs feed by absorbing energy and the more they absorb, the bigger and stronger they become.

P'andor was shown actually eating uranium as well, showing the species can eat physical things well as absorbing radiation, though it is unknown if they can eat non-radioactive substances.

Powers and Abilities

Prypiatosian-Bs are capable of firing highly radioactive energy beams which can corrode or melt metallic objects. The energy Prypiatosian-Bs radiate is hot enough to melt solid metal and rock through mere contact.[1] This energy can also be found in their saliva.[2]

Prypiatosian-Bs can channel their heat underground, which results in the eruption of massive geysers of lava.[3]

Prypiatosian-Bs are capable of producing their radioactive energy with their hands while inside their suit.

A Prypiatosian-B's containment suit is fireproof, being able to resist a Methanosian's fire attacks.[4] Overall, the containment suit is virtually indestructible against most attacks.[5]

Because the containment suit is made of metal, Prypiatosian-Bs are immune to being possessed by a Lucubra.[6]

Prypiatosian-Bs are quite strong, as NRG can carry Liam[2], throw a Vaxasaurian off his suit[4], hold the head of Sunder[7] and Swamps[4] and fight on par with the Trash Monster.[8]

Prypiatosian-Bs are immune to radiation and extremely hot environments;[9] this feat was first demonstrated by Ultimate Aggregor during his visit to the planet Mikd'lty.[10]

A Prypiatosian-B's radioactive energy can melt ice, such as the ice breath of a Necrofriggian.[4] They are also immune to extremely cold environments thanks to the heat they generate, as demonstrated by Ultimate Aggregor.[10]

Without their containment suits, Prypiatosian-Bs can manipulate energy at a higher level and are able to consume it simply as nourishment or to increase their power. They can also fire energy balls and blasts out of their hands and mouth.[11]

Prypiatosian-Bs can make themselves glow like a light bulb, which is bright enough to weaken Ectonurites.[12]

Prypiatosian-Bs can absorb an Aerophibian's neuroshock blasts, as demonstrated by P'andor.[5]

Prypiatosian-Bs can breathe underwater and grow in size if they absorb and consume enough energy; these feats were also demonstrated by P'andor.[5]

Prypiatosian-Bs are immune to being controlled by a Vladat via their Corrupturas by mimicking the radiation of a star.[DJW 1]

Prypiatosian-Bs are immune to being poisoned by lead.[DJW 2]


A Prypiatosian-B's containment suit completely removes several abilities, such as their agility and phasing. As such, they are unable to fly while in their containment suit.[13] On the other hand, the suit increases their physical strength.

Taydenite is the only known element that can damage a Prypiatosian-B's suit, outside of the suit itself.[5] Likewise, the Kraaho are the only known beings strong enough to rip open the suit.[11]

Prypiatosian-Bs have a strength limit, as NRG was unable to rip the Cassiopeian Dream Eater off his armor.[14]

Prypiatosian-Bs can be frozen and immobilized by ice, such as that generated by a Necrofriggian. Although their suits are heat resistant, they can still be slowed down by fire attacks.[4]

The eye holes in a Prypiatosian-B's suit are quite small, making their vision somewhat limited. They can be blinded even further by adhesives, such as those used by Sunder.[15]

Prypiatosian-Bs are vulnerable to carbon dampening rods because they can slow down nuclear reactions, thereby inhibiting the radiation they generate, as demonstrated with P'andor.[5]

Similar to Pyronites, a Prypiatosian-B's powers can be negated when exposed to enough water, such as that generated by an Orishan.[5]

Certain species can withstand a Prypiatosian-B's radiation including Slimebiotes[DJW 3] Aerophibians, and Evolved Arburian Pelarotas, the latter two of which has been demonstrated with P'andor.[5]

A Prypiatosian-B's radioactive blasts can be absorbed by the plasma generated by members of Ball Weevil's species, as demonstrated with Leander.[16]

Notable Prypiatosian-Bs

Notable Prypiatosian-B Hybrids


Pripyat is the Ukrainian city where the Chernobyl disaster occurred in 1986.


  • P'andor was sealed in the suit by his people because he is a criminal and the suit would act like his cage to weaken his powers no matter where he was.[DM 2]
  • Although Prypiatosian-Bs don't have fingers, their armor's gauntlets have fingers and Prypiatosian-Bs can use them as if they had hands.
  • Because the Prypiatosian-Bs are from the Andromeda Galaxy, Prypiatosian-B DNA wasn't in the Codon Stream until the Ultimatrix scanned P'andor in Too Hot to Handle.
