A Luminaris, a nocturnal, jellyfish-like Pokémon, has a translucent, gelatinous body that glows with a soft blue-green luminescence, while its umbrella-shaped head is adorned with iridescent, swirling patterns that shift between hues of purple and pink. Six feathery, crystalline tentacles dangle from its head, each tipped with a glittering, crystalline structure that refracts and reflects light. As a Psychic/Water-type, the Luminaris has the ability to create powerful illusions and manipulate water molecules to create intense whirlpools. It can also use its bioluminescent body to blind its opponents or communicate with its allies over long distances. The Luminaris is known to drift through the ocean, its ethereal glow attracting schools of sparkling fish that swim in synchrony with its movements.
