Shiny Pokémon were first introduced in March 2017 with the surprise reveal of Shiny Magikarp and its evolution, the red Shiny Gyarados.

Over years we've seen a variety of shiny Pokémon released into Pokémon Go, including Shiny Pikachu, Shiny Blitzle and legendary Pokémon like Shiny Tapu Koko. It will be interesting to see which unique variants come next!

Shinies are notoriously rare, as any veteran of the main series will gladly tell you, so what do we know about Pokémon Go Shinies, and how do you catch them?

How to find Shiny Pokémon such as Shiny Magikarp and Red Gyarados Pokémon Go

Shinies are found by simply trying to catch Pokémon and seeing if they display as an alternate colour in the battle and post-battle screens.

They won't appear as a different colour in the field, so you have to attempt to catch them first.

They of course can also appear in anywhere you'd find a Pokémon, not just the wild - so that includes hatching Eggs, Research task rewards and Raid bonus challenges.

A Shiny creature is extremely rare, so it's simply a case of checking every one you are looking for - such as Magikarp - in the hope it will be a different colour.

Often, the variation is somewhat subtle. You can see the difference in Magikarp in the above comparison image, courtesy of Silph Road subreddit user skinnysnorlaz.

Pokémon Go Shiny list and rarity tier list

Around five months after Shiny Magikarp was first sighted, we started to see the first sign of other shinies.

Though the list has expanded greatly since the arrival of Magikarp and Red Gyarados, the number is small compared to the number of non-shiny creatures in the game.

At a glance, here is every possible shiny creature you can get in the game right now (aside from additions since early February - you can see a more up-to-date list in chronological order later in the article) and their rarity according to a user survey (thanks to AirbenderProdigy on reddit for the research and image):

When and how every Shiny was added to Pokémon Go

Magikarp and Gyarados: The first Shiny Pokémon in Pokémon Go were Magikarp and Gyarados in March 2017 which were a callback to what was, for most players, the first Shiny they ever caught: the Red Gyarados at Pokémon Gold, Silver, and Crystal's Lake of Rage.

Shiny Pikachu: August 2017's Pokémon Go Park event in Japan revealed the second set of Shinies.

Those within the event radius had a chance of catching a Shiny Pikachu, which much like the Red Gyarados, could also be evolved into a shiny Raichu.

These have since been made available around the world, and was expanded on with a shiny hatted Pikachu as part of the 2018 Pokémon Day.

Shiny Gen 3 Ghosts: As the Halloween event in 2018 - which introduced the first Gen 3 creatures - rolled on, shiny variations of all five new creatures (Duskull, Dusclops, Shuppet, Sableye and Banette) started to appear.

Here is a video of shiny Duskull in action:

Shiny Gen 3 Raids: With the arrival of 50 Gen 3 creatures in December 2017 came two Raid-specific catches, both of which offering Shiny versions. The remaining 48 also have Shiny models in the game code, though none have been found so far.

Shiny Gen 3 Desert update: The Aron family of creatures all have shiny variants as part of their release in the Janary 2018 Gen 3 Desert update.

Shiny Gen 3 Dragon update: Swablu is one of the few creatures available as a shiny Pokémon, changing its blue body colour into yellow.

Evolving into Altaria will keep that same yellow colour scheme, as shown in this video by Cychreus Gaming:

Valentine's Day 2018: Alongside increased Luvdisc spawns came a shiny version:

Otherwise, there are no other signs more Shinies will be added. The main games had shinies for every single creature, so there's a chance every one in Pokémon Go will offer them at some point, but it makes sense Niantic would want to drip feed them for special occasions and make them more of an event.

Lunar New Year event 2018: The increase in dog and dog-like spawns saw the introduction of a shiny Poochyena:

Community Day: The creature a Community Day focuses on will release a shiny version at the same time. So far we've had:

The Max Out Season is here and includes a new global event, Wild Area, and the current 2024 Halloween event brings us Morpeko and the Halloween cup. You can now catch Dynamax Pokémon through Max Battles. First, however, you need to visit Power Spots to collect Max Particles and complete the To the Max! quest. Don't forget to try out Routes, Gift Exchange and Party Play while you're hunting down rare Pokémon, fighting in the Go Battle League or competing in PokéStop Showcases.

Other things to know about Pokémon Go Shinies - independent Shinies, Shiny Ditto and more

Aside the from the basics, there are a few other important points to note about Shiny Pokémon and the way they operate:

Shiny Pokémon are independent - in other words, two people can go to the same place and catch the same Magikarp, which has the same stats and IVs, but they won't necessarily both be Shiny. This is generally seen as a good thing by the community: it means people won't all be rushing to the same place after a Shiny is spotted, and 'spoofers' who cheat the system to change their location won't be able to instantly grab a Shiny as soon as one is located.
Shiny Pokémon can also be other 'states' of creatures - meaning they can also be Lucky, Shadow and Purified.
Shiny Pokémon's evolutions will be Shiny too - the good news, at least, is that Shiny Pokémon will evolve into Shiny Pokémon. So that means a gold Magikarp will turn into a red Gyarados when evolved, and so on. Another reason to hold onto those Candies for any Pokémon you encounter!
Shinies have their own entries in the Pokédex - Once you have found a Shiny, visit that creature in the Pokédex and you can view its unique appearance, alongside any gender differences. The following image by Dronpes explains this in closer detail:

Shiny Pokémon show up as standard colour Pokémon on the map - they only reveal themselves as Shiny once you start the battle sequence with them, which means checking every Pokémon you see now if you want to find Shinies, even if you've already caught plenty of that Pokémon!
There's a new warning if you try to transfer a Shiny - if you try and send a Shiny to Professor Willow, you'll get an additional pop-up warning checking that you definitely want to transfer this Shiny Pokémon. A nice touch to stop any fat finger issues!

That's all the important info you need - the rest of it is down to good old fashioned luck, so it's time get searching!
