The sentient Ultimate Big Chill looks just like Ultimate Big Chill, except he has red eyes and lacks the evolved Ultimatrix symbol on his chest.
In The Ultimate Sacrifice, the sentient Ultimate Big Chill, along with the other Ultimates, convinced Ben to commit suicide so they can be free, Ben tried to, but was stopped by Azmuth and they were freed by him and sent to a planet where they could live in peace.
Powers and Abilities
The sentient Ultimate Big Chill can become intangible, manipulate ice, fly, and breathe ice like regular Necrofriggians, but can create "ice flames", which his Ultimatrix counterpart describes as "fire so cold it burns".
These flames are plasma beams that consume the heat of whatever they touch and use that energy to burn.[DM 1][MW 1] The sentient 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. In fact, his ice breath is comparable to blizzard winds and it spreads farther than the breath of regular Necrofriggians.
The sentient Ultimate Big Chill can breathe or shoot flames from his hands that turn into blue ice when they hit a target. This form of ice freezes the enemy much faster than a regular Necrofriggian's ice breath.
By inhaling deeply, the sentient 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.
The sentient Ultimate Big Chill is also capable of much faster flight than his previous form.
The sentient Ultimate Big Chill can also survive in a variety of environments, including the vacuum of space, extreme heat, intense cold, and deep oceans.
The sentient Ultimate Big Chill's intangibility is useless against opponents who can also turn intangible, as it will cancel out their abilities to do so.
