There are several Pokémon that you can catch and add to your collection in Pokémon Go. Depending on the event that occurs in the mobile game, some Pokémon may have increased spawns, giving players more opportunities to catch them throughout the year. For example, if you're looking for a Natu to evolve into a Xatu eventually, it's a fairly common Psychic-type that appears in the game. Being so common, can you catch a shimmering Natu?
The shiny version of this Pokémon is available in Pokémon Go. You should have a chance to catch it, but the chances of it appearing are low. If you're attempting to catch a shimmering Natu in the wild, you have a one in 450 chance of it happening, which means you'll have to encounter many before you see one. Even if a Pokémon is present in a Featured Hour, it will not have a higher Brightness rate. Spotlight Hours increases a Pokémon's spawn rate, but its chance to shine remains the same.
Natu and his evolved form, Xatu, are at the lower end of the PvP league. Therefore, they are not the best choices for the Great, Ultra or Master League and we highly recommend not using them. You may be able to use them in smaller raid battles or even PvE battles against Team Rocket recruits. However, ultimately these two are mostly Pokédex fillers, which makes catching their bright versions at least once a more worthwhile undertaking.
