Shiny Heatmor Pokémon GO: How to Catch
If you're in GO Fest 2020, you'll be able to catch Heatmor when the Fire habitat rotates in. Each of the five habitats will rotate throughout the day.
If you're not in the event, you'll be able to catch a wild Shiny Heatmor after the event ends. Either way, it'll be tough to find. The Shiny spawn rate for the event is unknown, but the normal Shiny rate is about one in 450 encounters.
Shiny Pokémon don't appear on the map, so you'll have to encounter each Heatmor you see. You'll get a sparkle to denote that it's Shiny. A Shiny Heatmor is darker all around than the normal variety. It looks like if you left a normal Heatmor in the toaster too long.
In combat, Heatmor is an unusual Fire type that can learn the Ghost type Lick. It can also offer unusual coverage for a Fire type Pokémon with the Fighting type Power-Up Punch and Electric type Thunder Punch. Heatmor is a rogue pick that can surprise some opponents in Great and Ultra League.
