Mesprit is a small, gray, fairy-like
Pokémon. It has two tails that each have a red jewel encrusted in them. These are, presumably, two of the jewels which comprise the Red Chain. Mesprit has a partially magenta face with four long, drooping appendages and another red gem encrusted in its forehead.
Mesprit's spirit can leave its body without dying and return to the body at will. Legends say that a person that touches it will have their emotions completely drained away. Mesprit was highly feared due to it punishing those who
disrespect it; Mesprit will throw their emotions into disarray. Mesprit is said to have taught humans the ability to feel sorrow, pain, and joy. It was shown in The Needs of the Three! and The Battle Finale of Legend! that it can teleport itself, as well as other Pokémon and humans. Though playful, it is a bit
mischievous. Mesprit is known as "The Being of Emotion". Mesprit and the other lake guardians have the power to calm Dialga/Palkia should the deity be enraged. In
Pokémon Legends: Arceus, Mesprit is shown to be capable of speech via telepathy.
Mesprit and the other lake guardians are the only known Pokémon capable of learning the move Mystical Power.
