Pokémon Legends: Arceus may introduce many new systems, but it also makes sure to include some of the classic elements that veterans of the series love. Shiny Pokémon return to Arceus and, at some point in the story, players will need a Shiny Ponyta.
It sounds daunting, as we are all aware of the way Shiny odds work in the game. The good news is that there is a guaranteed way to get your hands on a Shiny Ponyta /
How to get a Brilliant Ponyta in Pokémon Legends: Arceus
The Peculiar Ponyta Challenge will appear after defeating Kleavor and returning to the Galaxy Building. Professor Laventon will send you in search of a Ponyta of a different color from the others in the region.
Thankfully, finding the creature is easy enough, and all you have to do is follow the search markers. You can then fight and capture the Ponyta. If things don't go your way, it's a static encounter, so you can just restart it. Take the Ponyta back to the Professor and you will receive your assorted rewards along with the Shiny Ponyta to add to your party if you wish.
If you level the Ponyta at 40, it will evolve into Rapidash, a type of fire with a lot of speed that is a great addition to any party.
