Big Chill

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

Ben as Big Chill
Big Chill is a humanoid, moth-like alien whose four wings and antenna can fold up into a hooded robe (much akin to a poncho), giving him the appearance of a phantom.

Big Chill has a blue body with black and white spots on his arms and legs that resemble ice chunks, a light blue torso, and large green eyes. He has three pointed fingers and a thumb on each hand, and two toes on each foot and a third toe-like extension on his ankles. Big Chill wears the Omnitrix/Ultimatrix symbol on his chest.

In Heroes United, he has a paler color scheme. The spots on his body are not symmetrical. He also has five fingers instead of four.

In Omniverse, Big Chill has a much more muscular build, also now having larger eyebrows and sharper ears. He has a belt on his waist where the Omnitrix symbol is located. He has bigger wings, claws, and a black beard design under his chin. 15 year old Big Chill in Omniverse looks exactly the same, but he lacks the belt and the Omnitrix symbol is on his chest.

Albedo as Negative Big Chill
In Omniverse, Negative Big Chill looks just like Ben's Big Chill in Omniverse, but has a paler color scheme, a red belt, and red eyes.

Powers and Abilities
Big Chill is capable of breathing a freezing vapor that reduces the temperature surrounding the vapor, encasing targets in ice. He can generate ice beams from his hands that he can manipulate. In Vilgax Attacks, Big Chill was capable of generating spiked balls of ice around his fists, as well as hurling ice spikes. He could also cause these spikes to sprout from the ground that surrounds him. In Cosmic Destruction, it was revealed that he can attack with an, "icy uppercut," as well as manipulate the cold around him to make a frosty tornado.

Big Chill's body contains a density-altering protoplasm that allows intangibility.

Big Chill has enhanced strength. In Save the Last Dance, when Big Chill was on a metal-eating spree, he effortlessly ripped apart a large metal statue and snapped iron girders in half. This strength also extends to his jaws, as Big Chill was capable of chewing up metal statues, poles, buildings, signs, iron girders, serving trays, and drinking molten steel.

Big Chill is completely immune to extreme subzero temperatures. He is also able to resistant to extreme heats. It was revealed in Deep that Big Chill can survive underwater. Big Chill can also survive in the vacuum of space.

Weaknesses
Big Chill's intangibility is useless against opponents who can also turn intangible as their intangibility cancels out. The only known inanimate objects that have proven to physically contact intangible Big Chill are the Rust Bucket's netting, Vilgax's glove, and the Techadon Robots' defense systems.

Big Chill's intangibility is consciously used, not reflexively, which means he can't use his intangibility if he is caught off guard.

Big Chill's ice breath is useless against Psycholeopterrans, Hypnotick's species.

Big Chill's wings are weak against electricity.
