Mega Gyarados is a solid but not elite Water-type attacker, sitting at Tier B (#12) in raid performance. With a max CP of 5,332 and base stats of 292/247/216, it can fill a role on your team if you lack stronger Water-type counters. The best moveset is Waterfall paired with Hydro Pump. Consider investing if you need a Water-type attacker now, but hold off on XL Candy investment as better alternatives exist. A useful stepping stone rather than an endgame pick.
