Big Chill

Big Chill is the Codon Stream's DNA sample of a Necrofriggian from the planets Kylmyys and Mykdl'dy.

Appearance
Big Chill is a humanoid, moth-like alien whose wings and antenna can fold up into a hooded robe, giving him the appearance of a phantom. He has a black body with blue and white spots on his arms and legs that resemble ice chunks, a light blue torso and large green eyes. He has three fingers and a thumb on each hand and two toes on each foot and a third toe-like extension on his ankles for balance.

Powers and Abilities
Big Chill is capable of breathing a freezing vapor that automatically lowers the temperature within the vapors range, encasing his targets in a thick layer of ice. Big Chill can generate freezing beams from his hands that he can manipulate at will. He can spit ice crystal projectiles. He is also strong enough to lift a car.

Big Chill's body contains a density-altering protoplasm that allows him to render himself intangible and invisible. He can combine his cryrokinetic abilities with his intangibility to freeze objects he passes through. Because he can alter his density, Big Chill can levitate and fly to a certain extent without using his wings (though he is much faster if he uses his wings).

Big Chill is not only immune to the effects of extreme cold, but is easily capable of surviving extreme heat. In Deep, he is shown to be able to survive underwater.

Weaknesses
Big Chill sometimes has trouble phasing through certain types of energy (e.g. in Good Copy, Bad Copy, Big Chill was harmed by Brainstorm's electrical storms), although in Save the Last Dance, he had no trouble phasing through the factory guards' plasma blasts. His intangibility is useless against opponents who can also turn intangible as their intangibility cancels out. Big Chill's powers are consciously used, which means he can't use his powers if he is caught off guard. The only objects that have been proven to be able to touch intangible Big Chill are the netting from the Rustbucket, Vilgax's glove and other intangible things.
