Evolved Necrofriggians (also known as Necrofriggian Ultim)[merch 1] are the evolved counterparts of the Necrofriggian species.


Evolved Necrofriggians have a red and black body with red spots on their arms and legs, a red torso and red eyes. They have three pointed fingers and a thumb on each hand and two toes on each foot and a third toe-like extension on their ankles.

An evolved Necrofriggian's wings and antennae have a flame design.

Powers and Abilities

Evolved Necrofriggians can become intangible, manipulate ice, fly, and breathe ice like regular Necrofriggians, but can create "ice flames", which Ultimate Big Chill describes as "fire so cold it burns".[1]

These flames are plasma beams that consume the heat of whatever they touch and use that energy to burn.[DM 1][MW 1] An evolved Necrofriggian's breath and beams are both stronger and colder, capable of instantly turning the air around them and their enemies into solid ice.[2] In fact, their ice breath is comparable to blizzard winds and it spreads farther than the breath of their normal counterparts.

Evolved Necrofriggians can breathe or shoot flames from their hands that turn into blue ice when they hit a target.[2] This form of ice freezes the enemy much faster than a regular Necrofriggian's ice breath.

By inhaling deeply, evolved Necrofriggians can lower the temperature of the air they breathe in, because they suck the heat out of objects, freezing anything that happens to be in its path.

Evolved Necrofriggians are also capable of much faster flight than their devolved counterparts.

Like regular Necrofriggians, evolved Necrofriggians can also survive in a variety of environments, including the vacuum of space, extreme heat, intense cold, and deep oceans.[3]


Vulnerability to Electricity

An evolved Necrofriggian's intangibility is useless against opponents who can also turn intangible, as it will cancel out their abilities to do so.[4]

Like their devolved counterparts, evolved Necrofriggians are vulnerable to electricity, such as that generated by a Transylian.[5]

An evolved Necrofriggian's ice flames cannot hold Pyronites because of the heat they generate, as demonstrated with Sentient Ultimate Big Chill.[6]

Evolved Necrofriggians can be knocked out of the sky by species with as much strength as a To'kustar, as also demonstrated by Sentient Ultimate Big Chill.[6]

Notable Evolved Necrofriggians

Notable Evolved Necrofriggian Hybrids


The word Necrofriggian comes from "necro", meaning dead and "frigid", meaning very cold.


  • An evolved Necrofriggian's voice is more gravelly than a Necrofriggian's, having a deeper tone behind it.
  • The Ultimate Alien Database on the Ben 10 Ultimate Alien: Power Struggle DVD incorrectly claims that their homeworld is Kylmyys Ultim, despite the species being artificial.[merch 1]
