Ans. The odds of encountering a perfect IV shiny Pokémon (100% IV) in Pokémon GO are extremely low. Shiny Pokémon typically have a base rate of about 1 in 500 to 1 in 650 for wild encounters, while perfect IVs are determined randomly. This makes the odds of finding a perfect IV shiny Pokémon quite rare, estimated at about 1 in several thousands.
