Lagralia is a humanoid-bird looking Pokémon, similar in some aspects to Lugia. It has a small head, with two wing-like hair pieces. Its arms have turned into two large wings. Its upper body and lower body are connected by a pearl-like object at the center of its body. The cone-shaped skirt of Luumin remains, but is enlarged.
Like Luumin, Lagralia has the power to purify all things unpure and can boost the moral of all people and Pokémon around it. It can instantly control the minds of all Normal-type Pokémon around it, and with its unique ability, Dark Absorption, it can nullify the effects of all Dark-type moves used on it and around it.
It also has the power to create Normal-type Pokémon and use every Normal-type move in existance.
