Both Voltorb and Hisuian Voltorb can be shiny in Pokémon Go, and their distinct shiny forms make shiny hunting worthwhile despite their lack of meta relevance.
According to research, shiny Pokémon have a catch rate of approximately one in 500, but Voltorb does not get a 'permaboost' and its shiny rate remains random.
Shiny rates for Pokémon are only typically boosted during special events like Community Days or Safari Zones, with no items available to enhance shiny rates.
For a comprehensive view of available shiny Pokémon, LeekDuck offers a visual guide showing the appearances of all shiny forms currently in the game.
