Kyurem

Kyurem is a gray and blue, bipedal Pokémon of indefinable but seemingly draconic basis. Kyurem has a blue head and snout and has yellow eyes without pupils, a pair of pointed light bluish horns on its head, and a yellow crest on its skull that is bioluminescent. Three pointed teeth jut out the bottom of either side of its jaws, which are frozen shut by the ice covering its head. Its long, gray neck has lines running around its whole body, legs, arms, and tail. It has two arms, each with its claw, and each arm is joined together by its oddly shaped blue wings, which are believed to be used for flying and storing cold air. Each wing has two spikes of ice that are also bioluminescent. The ice covering the wings can break, revealing gray tendril-like appendages on Kyurem's back.

The right side of its body seems to be damaged in some way, as the wing and horn on its head on that side are shorter; the right side of its head also has a spiked edge near its jaw hinge that is absent from its left. Its legs are somewhat slender and have three sharp ice-like claws on each enormous foot. Its tail has three blue conical spikes on its tip, and appears to be some sort of propulsion device or a container of energy; exactly what it is based on is unclear, but it may be a damaged turbine.

Kyurem generates powerful, freezing energy inside itself, but its body becomes frozen when the energy leaks out. By keeping its body frozen, the cellular structure will remain stable. It is said to have a power that exceeds that of and ; however, this power is kept at bay by the extreme cold. Kyurem can transform both Rehsiram and Zekrom back into their respective Dragon Stones by using its tendril-like appendages. Due to an old legend, it may be assumed Kyurem may be hostile towards Pokémon and humans, due to the fact it supposedly ate them if they were found outside at night. In the manga, similarly to Reshiram and Zekrom, Kyurem is somehow capable of flying even with its frozen wings. It is said to be an extraterrestrial Pokémon, according to folklore. According to the anime, Kyurem is considered one of the strongest Dragon-type Pokémon in the world. Kyurem is powerful enough to cover an entire region in which it resides in ice, potentially freezing it. Kyurem loves Kyurem Treats made by Snacksworth, who once encountered it in the past.

Forms

Kyurem has two alternate forms: White Kyurem and Black Kyurem, which are formed by combining with Reshiram and Zekrom, respectively, sharing many aspects of their designs with them. It can use Absofusion on their respective Dragon Stones to change to White or Black Kyurem. The reason for this is due to Kyurem retaining the gene of the other dragons which allows said fusion. As a result, Kyurem also shares Reshiram's or Zekrom's beliefs in truth or ideals, respectively, when fused with either of the two dragons. In Kyurem VS. The Sword of Justice, Kyurem can also change into Black Kyurem or White Kyurem without fusing by channeling the powers of both Reshiram and Zekrom it has within itself.
