Question: do shinies appear in the overworld pokemon sword?
Answer: Unlike the Let's Go series, shiny Pokémon won't appear in the overworld and you won't know if you can catch one until you go into battle. ... Pokémon Sword/Shield give you extra rerolls to try to generate a shiny based on how many of the Pokémon you've ever battled, and how long your current encounter chain is.
