No, Gigantamax Rillaboom cannot be Shiny in Pokemon Go, as of yet.

Typically, Shinies debut a year after their regular versions, and since Grookey (Rillaboom’s base stage) was introduced in September 2024, players will likely have to wait until 2025’s second half to see if its Shiny version is unlocked.

Once it does, Shiny Rillaboom and subsequently Shiny Gigantamax Rillaboom will be relatively easy to spot as their deep green grassy details change to lime green.

Anyhow, remember that the odds of coming across a Shiny Pokemon are very low, and there’s no special method to secure an encounter.
