Slugma, the lava Pokémon from Johto, can be found in the wild in Pokémon Go. Yes, Slugma can be shiny in Pokémon Go!
You won’t see neither Slugma nor Magcargo get any use in PvP or PvE content, but it’s a pretty good shiny! It’ll be a hard decision whether or not to evolve your sweet silver slug into a slay hot pink snail.
What is the shiny rate for Slugma in Pokémon Go?
As per old research by the now-defunct website The Silph Road (via Wayback Machine), the shiny rate for Pokémon on a regular day is approximately one in 500. Slugma is not a confirmed Pokémon that gets a “permaboost” (meaning that it’s a rare spawn and thus gets a boosted shiny rate).
What can I do to attract more shiny Pokémon?
Not much, unfortunately. It appears to be random chance. Shiny Pokémon catch rates are set by developer Niantic, and they are typically only boosted during special events like Community Days or Safari Zones, or in Legendary Raids. There are no consumable items that boost shiny Pokémon rates.
Where can I find a list of available shiny Pokémon?
LeekDuck keeps a list of currently available shiny Pokémon. It’s a helpful visual guide that illustrates what all of the existing shiny Pokémon look like.
