Shiny Perrserker is Perrserker's shiny form: a different colour, and stronger, with 30% more health and move damage than a normal Perrserker. Shinies are the strongest Pokémon in the game.
How rare it is
Every Perrserker you defeat on a map has a 1 in 15,000 chance to drop Shiny Perrserker. A hunting chain on Perrserker makes it up to 4× likelier, and the Shiny Charm 1.5×.
Where to find it
Beat Perrserker on these maps (a shiny sometimes defends a map itself, stronger than its kind):
| Map | Region | Level |
|---|---|---|
| Crown Tundra | Galar | 86 |
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.
