Shiny Gligar Pokemon GO: How to Catch
Catching a Shiny Gligar is pretty simple: just find one and go. The hard part is finding one, as Gligar isn't the most common thing to see. You can only find it in the Woodland environment, so you'll have to hang out in the forest until you find one. There is now just the possibility of encountering a Shiny Gligar, and it is unknown currently if the rate of a Shiny encounter has been increased or not.
A Shiny Gligar is only slightly more bluish purple than the normal red purple. It actually looks like how the original Gligar art was colored back in Gold/Silver, so it might be hard to distinguish. Like all Shiny Pokemon, there will be a sparkle to denote if the one you've met is indeed a Shiny.
There are a variety of other bonuses as well, such as double incubator effectiveness for the duration of the Ultra Bonus and Raikou, Entei and Suicune returning to Raids. The event will run until Sept. 9, so you have until then to find Shiny Gligar.
