Shiny Gloom is Gloom's shiny form: a different colour, and stronger, with 30% more health and move damage than a normal Gloom. Shinies are the strongest Pokémon in the game.
How rare it is
Every Gloom you defeat on a map has a 1 in 6,000 chance to drop Shiny Gloom. A hunting chain on Gloom makes it up to 4× likelier, and the Shiny Charm 1.5×.
Where to find it
Beat Gloom on these maps (a shiny sometimes defends a map itself, stronger than its kind):
| Map | Region | Level |
|---|---|---|
| Celadon Gym | Kanto | 11 |
Evolving it
A shiny evolves into the next form's shiny, which is rarer, so it also needs Glimmer Stones:
- Evolves from Shiny Oddish with 2 Glimmer Stones
- Evolves into Shiny Vileplume with 2 Glimmer Stones, on top of what Gloom needs
- Evolves into Shiny Bellossom with 2 Glimmer Stones, on top of what Gloom needs
Past level 100
A shiny never becomes a Nightmare form: at 5★ and level 100 it Ascends instead, keeping its shine and its name, and climbs the Nightmare ranks to level 999. See The Nightmare World.
