Is Mega Gyarados good in Pokemon GO?

Situational

Power up	Stardust	Candy	XL Candy
Lv 20 → 40	135,000	15	—

Tier B at rank #14 makes Mega Gyarados a useful Water-type filler rather than an endgame pick. Build one if your Water bench is thin, but keep the XL Candy for something stronger.

Attack is its highest stat (292), so it hits harder than it survives — a glass-cannon raid slot rather than a gym defender.
A second charged move costs 10,000 Dust and 25 Candy, and with 6 charged moves to pick from it is the single biggest PvP upgrade you can buy.
Its moves get a damage boost in Fog and Rainy weather — worth timing raids around.
