Big Chill is the Omnitrix's DNA sample of a Guardian Necrofriggian from the planet Mykdl'dy .
Big Chill is a humanoid, moth-like alien whose four wings and antenna can fold up into a hooded robe, giving him the appearance of a phantom. He has a black body with bluish-white pads on his arms, shoulders and legs, and patches of the same color on the back of his wings and his neck, which resemble ice chunks. Each pad has thick blue outlining except for the patches on his wings, which are outlined in black. There is also a black line that runs on the edge of the outer margin on the back of each wing.
On his torso are three plates: one resembling the chest, a shorter plate under the chest, and one resembling the stomach. On his face are black cheeks and underjaw, a mouth that always shows bluish-white teeth, and large green eyes with dark green spots. The top of his head also sports a blue Y-shaped marking that extends over his scalp. He also has crystalline fingertips and toes.
Powers and Abilities
Big Chill is capable of breathing a gas, wind or beam that reduces the temperature surrounding it, turns to ice constructs mid-air or upon touching a target, or encasing a target completely in ice. His breath can be as strong as wind, capable of pushing the Rust Bucket 2 off a cliff.
He can become intangible, to the point where he can cause opponents and objects to freeze by phasing through them, though he can choose not to.
Big Chill has cryokinesis, allowing him to control the ice he generates at will. He can also generate ice beams from his hands which he can manipulate, being able to form manipulable ice constructs from the ground by touching it and can freeze objects just by touching them. In addition to that, he can create ice melee weapons, suck as a sword or a short spear.
Big Chill has enhanced strength, as seen when he was on a metal-eating spree, where he effortlessly ripped apart a large metal statue and snapped iron girders in half.
He is rather durable, as he was able to take a laser blast to the back from Kraab and only be slightly fazed. Despite this, Big Chill prefers to use his intangibility to avoid being hurt.
He is quite agile, as he is capable of dodging attacks while flying and is immune to extreme temperatures, both hot and cold. As such, he can drink molten steel.
Big Chill can survive underwater, as well as in the vacuum of space, and also levitate without using his wings. Big Chill has powerful jaws capable of chewing up metal statues, poles, buildings, signs, iron girders, and serving trays.
Big Chill's intangibility is useless against opponents who can also turn intangible, as it will cancel out their abilities to do so.
The only inanimate objects that have been able to touch intangible Big Chill are the Rust Bucket 2's netting, the Shield of Seagle, the Techadon Factory's defense systems, and the Plumber Headquarters' prison cell's door.
Big Chill's intangibility is consciously used, not reflexively, which means he cannot use his intangibility if he is caught off guard. Besides, his ice breath is useless against Psycholeopterrans such as Hypnotick. He can also be easily hypnotized by them.
Big Chill can be harmed by electricity, such as that from a Cerebrocrustacean and/or the Shield of Seagle.
Due to his pale skin, Guardian Big Chill can only be used in closed or dark areas, as not to damage himself with the sun's brightness.
