Mesprit

Physiology
Mesprit is a small, gray, fairy-like Pokémon. It has two tails that each have a red jewel encrusted into them. These are, presumably, two of the jewels which complement the Red Chain. Mesprit has a partially magenta face with four long, drooping appendages and another red gem encrusted into its forehead.

Gender differences
Mesprit is genderless, although it is referred to as a female in Pokémon Mystery Dungeon 2.

Behavior
Mesprit's spirit can leave its body without dying. Its spirit can return to the body at will. According to legend, it can drain one's emotions away by simply touching it.

Habitat
Mesprit sleeps in Lake Verity. Once it is encountered, it will run away, wandering around Sinnoh and only traceable with the Marking Map Pokétch app. Mesprit will warp to a new location whenever the player crosses the boundary between two areas except if the player passes through a gate between a city and a route, or if the player uses Fly.
