Somnivora

Black +2: The mist emanating from their foreheads is packed with the dreams of people and Pokémon.

White: With the mist from its forehead, it can create shapes of things from dreams it has eaten.

Black 2 +3: The dream mist coming from its forehead changes into many different colors depending on the dream that was eaten.

Sword: When dark mists emanate from its body, don’t get too near. If you do, your nightmares will become reality.

Shield: It drowses and dreams all the time. It’s best to leave it be if it’s just woken up, as it’s a terrible grump when freshly roused from sleep.
