Oh kay false alarm, nevermind, it just Arceus themed:
> An arc suit (Japanese: アルコス Arceus Costume) is a special type of outfit appearing in Pokémon Masters EX that is designed to resemble Arceus. They are granted, through the power of sync stones ultimate, to Trainers who have a very strong bond with their partner Pokémon. The outfits are said to have been blessed by Arceus. Once a Trainer has awakened their arc suit, they can freely switch between their normal outfit and their arc suit at will.
> Unlike sygna suits, which denote a sync pair formed with a different partner Pokémon than normal, arc suit sync pairs are new sync pairs formed with the same partner Pokémon. These sync pairs can be scouted to join the player's team through special sync pair scouts called Arc Suit Fairs.
