Ultimate Big Chill

Ultimate Big Chill is the evolved form of Big Chill.

Appearance
Ultimate Big Chill's wings and antennae have a flame design.

Ultimate Big Chill can make his wings and antennae fold into a cloak like Big Chill can, which looks no different from Big Chill's cloak, except for being red.

Ultimate Big Chill's voice is more gravelly than Big Chill's, having a deeper tone behind it.

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 "ice so cold it burns".

Dwayne described these flames as a plasma beam that consumes the heat of whatever they touch and use that energy to burn. Both his breath and beams are stronger and colder, capable of instantly turning the air around his and his enemies into solid ice. In fact, his ice breath can be similar to blizzard winds.

Ultimate Big Chill can breathe or shoot flames from his hands that turns into blue ice when they hit a target. His form of ice freezes the enemy much faster than Big Chill's ice breath.

In Cosmic Destruction, he can make large plasma blasts on the ground, which either freeze, damage, or both, as well as hurl fiery ice spikes at opponents from just above the ground.

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

Ultimate Big Chill is a much faster flyer than Big Chill.

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.

Weaknesses
Ultimate Big Chill's intangibility is useless against opponents who can also turn intangible as their intangibility cancels out.

Ultimate Big Chill's wings are weak against electricity.
