At 17:19 EDT a post was made on TheSilphRoad of a player claiming to have used their Go Plus to catch one of these Zorua; however, instead of reverting back to Zorua the Pokémon remained a Mewtwo. As it turned out, Zorua would retain the species that they had displayed on the map if they were caught using a Pokémon Go Plus or a Pokéball Plus. Shinyness was not retained & the IVs/level of the Pokémon would be randomly generated (Level 1-30, IV floor 0) but could be affected by weather boosts (Level 5-35, IV floor 4) based on the species being retained. It is unknown at this time if Pokémon caught with this method had any shiny chance at all.
This meant that Pokémon caught through this method could be found at lower levels than ever before, as well as with IV floors never seen before in Go.
It is worth noting that since players could only use the Pokémon Go Plus/Pokéball Plus for this glitch to occur, only Pokémon caught in a regular Pokéball could be obtained.
By October 28th at 18:04 EDT Niantic disabled all Bluetooth pairing within Pokémon Go rendering the use of this glitch impossible. As an added measure Zorua had its ability to disguise itself as legendary/Mythical Pokémon removed temporarily. At 19:12 EDT on October 28th, 2022 Niantic announced that Zorua that failed to transform when caught would be changed to Zorua at a later date. As of the time of writing - this has not happened yet but the post will be updated with information when it does.
