Now it's just you, me, and fire so cold it burns.

– Ultimate Big Chill to Vulkanus.[1]

Ultimate Big Chill is the Ultimatrix's artificially evolved DNA sample of a Necrofriggian.


Ultimate Big Chill looks mostly the same as his devolved counterpart in Alien Force and Ultimate Alien except his skin is recolored red, his wings and antennae have a flame design, and he had crests over his eyes with the same design. Similar to Big Chill, Ultimate Big Chill can make his wings and antennae fold into a cloak.

Ultimate Big Chill wears the evolved Ultimatrix symbol on his chest.

Powers and Abilities

Ultimate Big Chill can become intangible, manipulate ice, fly, and breathe ice like Big Chill, but can create "ice flames", which he 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] Ultimate Big Chill's breath and beams are both stronger and colder, capable of instantly turning the air around him and his enemies into solid ice.[2] In fact, his ice breath is comparable to blizzard winds and it spreads farther than the breath of his normal counterpart.

Ultimate Big Chill can breathe or shoot flames from his hands that turn into blue ice when they hit a target.[2] This form of ice freezes the enemy at a much faster rate than Big Chill's ice breath.

By inhaling deeply, Ultimate Big Chill can lower the temperature of the air he breathes in, because he sucks the heat out of objects, freezing anything that happens to be in its path.

Ultimate Big Chill is also capable of faster flight than his previous form.

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

Ultimate Big Chill can make it snow.[4][note 1]


Vulnerability to Electricity

Ultimate Big Chill's intangibility is useless against opponents who can also turn intangible, as it will cancel out their abilities to do so.[5]

Like his base form, Ultimate Big Chill is vulnerable to electricity, such as that generated by a Transylian.[6]

Ultimate Big Chill's ice flames cannot hold Pyronites because of the heat they generate, as demonstrated with his sentient counterpart.[7]

Ultimate Big Chill can be knocked out of the sky by species with as much strength as a To'kustar, as also demonstrated by his sentient counterpart.[7]
