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.
Big Chill has a black body with green and aqua spots on his arms and legs that resemble ice chunks, a green torso and large red 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.
Big Chill is capable of breathing a freezing vapor that lowers the temperature within the vapors range, encasing targets in ice.
Big Chill can generate ice beams from his hands that he can manipulate at will.
Big Chill is strong enough to lift a car.
Big Chill's body contains a density-altering protoplasm that allows him to render himself intangible.
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 can combine his cryokinetic abilities with his intangibility to freeze objects he passes through.
Big Chill is not only immune to the effects of extreme cold, but is also easily capable of surviving extreme heat.
Big Chill can survive underwater.
Big Chill can wield icy spike ball fists, hurl ice spikes, and make ice spikes come out of the ground around him.
it's revealed that Big Chill can make an "icy uppercut", and create a cold tornado.
Big Chill's intangibility is useless against opponents who can also turn intangible as their intangibility cancels out.
Big Chill's powers are consciously used, not reflexes, 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 intangible things.
- In The Evil Within, Drahcir used Big Chill to escape a force field at the team's base.
- In Relentless, Big Chill was used to cool down the areas on him that were affected by the acid from Hornado.
- In the Heroes of Today poster and Richard's flashback, Big Chill is two shades of yellow instead of green and aqua. This was an error. The two-shades-of-yellow-Big-Chill was his original design.
