In Let's Go Pikachu and Eevee, the Wild Pokémon appear in the overworld, which means a Pokémon in its Shiny form will as well. ... Like in every Pokémon game there are odds to encountering a Shiny Pokémon. The full odds for Shiny Pokémon appearing is 1 in 4096, but those odds can be improved using the Catch Combo system.
