科斯莫古

Sun: Its body is gaseous and frail. It slowly grows as it collects dust from the atmosphere.

Moon: In ages past, it was called the child of the stars. It’s said to be a Pokémon from another world, but no specific details are known.

Ultra Sun: Even though its helpless, gaseous body can be blown away by the slightest breeze, it doesn’t seem to care.

Ultra Moon: Whether or not it’s a Pokémon from this world is a mystery. When it’s in a jam, it warps away to a safe place to hide.

Sword: This Pokémon came from another universe. Its gaseous body is so light that even a gentle breeze can blow it away.

Shield: Cosmog is very curious but not very cautious, often placing itself in danger. If things start to look dicey, it teleports away.
