Kyurem

Kyurem, the Boundary Pokémon, is a frozen dragon that arrived on Earth when, according to legend, a comet crashed into the area that became the Giant Chasm. It went into the village called Lacunosa Town at night and brought with it a cold wind and stole people and Pokémon.

Kyurem is able to produce ultracold air and produces a freezing energy inside itself that caused its body to become frozen when it leaked out. It is also able to flash-freeze areas.

It also has the ability to merge with Zekrom or Reshiram by breaking the ice on it's wings, reavealing tentacle like limbs, and destroys them transforming them into thier corrosponding stones. After this prosces is done, the result is black kyurem (for Zekrom) or white kyurem (for reshiram).
