Cosmog

Cosmog, known as コスモッグ in Japanese, is a Psychic-type Legendary Pokémon introduced in Generation VII. It resembles a floating nebula, with colors ranging from dark blue to purple, and two light-blue, antenna-like structures on its head. Cosmog is curious and naive, showing no fear of people or Pokémon and readily trusting others, which often leads it into danger. Its body is fragile and easily blown away, but it seems unconcerned. Cosmog possesses spatial manipulation abilities and can open Ultra Wormholes when stressed. In the games, it evolves into Cosmoem and ultimately into either Solgaleo or Lunala, depending on the game version. Cosmog plays a significant role in the story, being referred to as the "Child of the Stars" and is closely tied to the legends of the Alola region.
