One of the newer additions to Pokemon GO, coming just a few short weeks after the 2nd Generation Update, was none other than that of Shiny Pokemon Forms. Beginning during the Water Festival Event in March 2016 with Shiny Magikarp appearing, players could begin finding certain Pokemon in their given Shiny Forms. More often then not, new Shiny Forms are released during Promotional Events or Special Updates. Much like the Pokemon Core Series Games, however, Shiny Pokemon are no more powerful than their regular forms.
At the present time, twenty-two different Pokemon can be found as a Shiny Pokemon: Pichu, Pikachu, Raichu, Magikarp, Gyarados, Poochyena, Mightyena, Sableye, Shuppet, Banette, Duskull, Dusclops, Mawile, Absol, Snorunt, Glalie, Swablu, Altaria, Aron, Lairon, Aggron, and Luvdisc. However, only the Pokemon listed that are the first Pokemon in their given Evolution Chains can be found in the Wild (or in Eggs) as a Shiny Pokemon. This means that in order to obtain a Shiny Gyarados or Shiny Banette, for example, you would have to find Magikarp or Shuppet as a Shiny Pokemon and then evolve them, as you can't find Shiny Gyarados or Shiny Banette in the Wild. The only exception to this is found with Pichu, Absol and Mawile: Pichu can only be found in Eggs, and thus can only be found as a Shiny from an Egg; Absol and Mawile, on the other hand, can only be found as a Shiny Pokemon when they are a Raid Boss.
Unlike the Mainstream Pokemon Games where the odds of finding a Shiny Pokemon are very slim, they are actually pretty common in Pokemon GO. At the very worst, it appears as though the odds of finding one of these Pokemon in their Shiny Form could be as low as 1 in 500. Many experts believe these odds can further be enhanced through a technique called chaining, where you only click on and battle the same species of Pokemon over and over again.
Players also won't know if one of these Pokemon is indeed Shiny while searching the Wild, as Pokemon won't appear as Shiny until a player clicks on and goes into battle with them. Shiny Pokemon will be of an alternate color compare to a Pokemon's usual appearance, and they will also have shiny stars appear around them in battle and in their Pokemon Profile Background as well. Furthermore, Professor Willow will even ask you twice about transferring a Shiny Pokemon, just in case you accidentally click on transfer and don't have the Shiny Pokemon as one of your favorites.
