Mega Gyarados's Tier Ranking & Meta Analysis

Mega Gyarados PvE Analysis

Recommended moves

Mega Gyarados is a powerful Water/Dark-type that performs decently well in both its types. The issue with this popular Pokémon is that it gets tremendously outclassed everywhere, primarily held back by the fact that its peers tend to have stronger moves. As a result, it often falls down the pecking order in Raids, as players have plenty of options to pick from.

Let's check out how this monster rakes up against other Water and Dark types, and if it can masquerade as a Dragon-type attacker.

🌊 Water type

Mega Gyarados’ best performance comes in the Water department where it takes advantage of its high offenses and powerful moves to deal high damage. The thing is, Mega Gyarados is not bad in any way, it's just outclassed by Pokémon that overtake this classic via stronger moves. While Primal Kyogre and its Shadow and regular variants have Origin Pulses , the Mega Evolutions and Shadows of Water-type Starters have the deadly Hydro Cannon.

Additionally, Shadow Gyarados itself deals more DPS and despite being flimsier, it performs quite well against Ground-type Raid Bosses due to its Flying subtyping.

🌑 Dark type

Mega Gyarados is competitive as a Water type but it is heavily outclassed in the Dark side. Mega Tyranitar , Shadow Tyranitar , Shadow Hydreigon, Shadow Darkrai, Shadow Absol , and even regular Darkrai , Tyranitar , and Darkrai offer more value in Raids compared to Mega Gyarados.

Sadly, against Ghost and Psychic Raid Bosses, Dark types like Mega Gyarados also have to compete with Ghost Pokémon for super-effective damage. With the latter typing housing powerhouses like Dawn Wings Necrozma , Mega Gengar , Blacephalon , and Shadow Chandelure , as well as Shadow Rider Calyrex, Mega Gyarados struggles to find a place for itself in the Dark-type role.

🐲 Dragon type

Mega Gyarados is no dragon but it learns several Dragon-type moves in Pokémon GO, which would make you think if it gets any viability given its high offenses.

Unfortunately, the Dragon-type crowd is too overpowered, giving Mega Gyarados a performance similar to Dragon Breath + Dragon Claw Dragonite (its weakest PvE Dragon moveset).

⭐ Perks

Delivers a solid performance if you're missing out on the Kyogre and Hydro Cannon Starter variants. With starters being highly accessible through Community Day events, you're bound to get one through special events or Community Day Classics, leaving Mega Gyarados in the dark, although viable.

Mega Gyarados PvP Analysis

Recommended moves

Mega Evolutions are typically not permitted in the GO Battle League and are limited to the Mega Master League, when available. In this limited format, Mega Gyarados is a monster that flexes an extremely high stat product and slays almost everything. 😳

Fairies like Xerneas, Togekiss, Enamorus Incarnate, and Charm Primarina are the only opponents it can't beat (it still beats Zacian and Waterfall Primarina), and takes down the rest of the meta. It's arguably the top Mega Evolution in the Mega Master League. 👏

💥 The best moves for Mega Gyarados in PvP are Dragon Tail, Aqua Tail, and Crunch.
