Are you trying to figure out how to beat Mega Gyarados in Pokemon GO?
Since June 17, 2021, Mega Gyarados has been added to the possible Mega Raid Boss list in Pokemon GO. This massive Flying / Water-type Pokemon will surely keep you at the edge of your seat the entire battle.
Gyarados hails from the Kanto region and evolves from Magikarp when fed 400 candies. You can then grow it to Mega Gyarados by giving it 200 Mega Energy the first time and 40 afterward.
Like any Pokemon, the key to defeating Mega Gyarados in raid battles is selecting the best Pokemon to counter its resistance and deal the most damage.
Besides, your current level and playing style would also decide the outcome when you go against a Mega Gyarados.
