NRG is one of Ben Tennyson's alien egos who first appeared in Ben 10: Ulitmate Alien. He is the Omnitrix's DNA sample of a Prypiatosian-B from Prypiatos, a planet in the Andromeda Galaxy.
Powers and Abilities
NRG is capable of firing highly radioactive energy beams through the vents in his containment suit which can corrode or melt metallic objects. The energy NRG radiates is hot enough to melt solid metal and rock through mere contact. This energy can also be found in his saliva.
NRG can channel his heat underground, which results in the eruption of massive geysers of lava.
NRG is capable of producing his radioactive energy with his hands while inside his suit.
NRG's containment suit is fireproof, being able to resist a Methanosian's fire attacks. Overall, the containment suit is virtually indestructible against most attacks.
Because the containment suit is made of metal, NRG is immune to being possessed by a Lucubra.
NRG is quite strong, as he can carry Liam, throw a Vaxasaurian off his suit, hold the heads of Sunder and Swamps and fight on par with the Garbage Monster.
NRG is immune to radiation and extremely hot environments; this feat was first demonstrated by Ultimate Aggregor during his visit to the planet Mykdl'dy.
NRG's radioactive energy can melt ice, such as the ice breath of a Necrofriggian. He is also immune to extremely cold environments thanks to the heat he generates, as demonstrated by Ultimate Aggregor.
NRG is immune to being controlled by a Vladat via their Corrupturas by mimicking the radiation of a star.
NRG is immune to being poisoned by lead.
NRG is able to easily open his containment suit and get out whenever he wants to. Outside the suit, all of NRG's powers are enhanced massively. He becomes very agile and gains both flight and limited phasing abilities.
Without his containment suit, NRG can manipulate energy at a higher level and is able to consume it simply as nourishment or to increase his power. He can also fire energy balls and blasts out of his hands and mouth.
NRG can make himself glow like a light bulb, which is bright enough to weaken Ectonurites.
NRG can absorb an Aerophibian's neuroshock blasts, as demonstrated by P'andor.
NRG can breathe underwater and grow in size if he absorbs and consumes enough energy; these feats were also demonstrated by P'andor.
In Too Hot to Handle, NRG's DNA was sampled and put in the Codon Stream when the Ultimatrix scanned P'andor's DNA.
NRG first appeared in The Forge of Creation, where he briefly fought 10-year-old Heatblast until the latter reverted.
In Absolute Power: Part 1, NRG was defeated by Ultimate Kevin. Later, NRG briefly battled Gwen before switching into Nanomech.
In The Transmogrification of Eunice, NRG was defeated by Sunder.
In The Creature from Beyond, NRG fought the Lucubra and created the pit Gwen needed to contain and send it back to where it belonged.
In The Purge, NRG battled Trumbipulor, but failed to stop him from escaping due to Argit's intervention. Later, NRG challenged Driscoll to a duel.
In Double or Nothing, NRG freed himself from Fridge's ice. Later, NRG fought Swamps and Hugh before switching into Spidermonkey.
In The Widening Gyre, NRG battled the Garbage Monster.
In Night of the Living Nightmare, NRG appeared twice in a dream. Firstly, Ben as NRG destroyed the Cassiopeian Dream Eater. Later, Negative NRG failed to defeat Ben before switching into Negative Brainstorm.
In The More Things Change: Part 2, NRG failed to catch Bubble Helmet, Liam, and Fistina.
In So Long, and Thanks for All the Smoothies, NRG defeated the Incurseans.
In Hot Stretch, NRG stopped the Kraaho from destroying the Earth with lava, during which his containment suit was opened and his true form was shown for the first time. He returned to the opened suit before the Omnitrix timed out.
In Showdown: Part 2, NRG helped defend Galvan Prime from a meteor shower from the destroyed Galvan B.
In Ben Again, NRG was used by 11-year-old Ben in 16-year-old Ben's body to find coordinates in a reactor.
In The Frogs of War: Part 1, NRG accidentally set a building on fire and tried to calm the crowd of humans before the Omnitrix's randomizer function switched him into Water Hazard.
In Rad Monster Party, NRG used his true form to make a very bright glow, which harmed Zs'Skayr due to the light.
In It's a Mad, Mad, Mad Ben World: Part 2, Mad NRG stopped the rebelling slaves.
In A New Dawn, NRG appeared for a short time when Ben was cycling through his aliens.
- NRG retains P'andor's armor, even though other Prypiatosian-Bs do not have it and it is not part of their genetic sequence. This is because it was added by the Ultimatrix as part of a life support system to keep him from causing radiation poisoning to those who are vulnerable to his radiation.
