How to Get Mega Gyarados

You cannot catch Gyarados in its mega evolved form from the raid. The mega raid boss is always catchable in its base form and as such, the CP ranges are for a regular Gyarados.

Gyarados can be caught with the following CP values:

1855 – 1937 CP no weather boost
2319 – 2422 CP boosted by Rainy or Windy weather boost

In order to get Mega Gyarados you will need 200 Mega Energy for the initial evolution, then 40 Mega Energy to evolve the same Gyarados again in the future. Mega Energy can be obtained via Mega Gyarados Raids, and once you have evolved Mega Gyarados, you can earn 5 Mega Energy per candy while walking it as your buddy. You can walk any Magikarp or Gyarados to earn Mega Energy, as long as you have previously evolved one to register it to your Mega Pokédex.

Shiny Gyarados & Mega Gyarados Sprites

Like all Mega Raid Bosses, you can catch the shiny version of Gyarados from a raid, and also in the wild potentially, if you can find it! Gyarados does have a slight gender difference in both the regular and shiny sprites, with its whiskers changing colour.

Regular Sprite (Male)	Shiny Sprite (Male)

Regular Sprite (Female)	Shiny Sprite (Female)

Here are the sprites for Mega Gyarados:
