Overview of Mega Gyarados
Gyarados is originally a Water and Flying-type Pokémon. When it activates its Mega Evolution, it becomes Water and Dark type. This new form greatly increases its damage output and its ability to take hits thanks to improved HP and Defense. In the Pokédex, Mega Gyarados retains Gyarados's number but gains additional information about its heightened power and even more violent temperament.
Its size is approximately 6.5 m and it weighs over 300 kg. In its shiny version, it takes on a dark red hue that is highly sought after by players during special events and in raids.
Stats and battle performance
Base stats
Mega Gyarados's stats are oriented toward Attack. Its Attack and HP increase significantly compared to standard Gyarados. Its Speed remains decent, allowing it to strike multiple times with great force. Its base stats make it a fearsome attacker both in competitive battle and in Pokémon GO.
Very high Attack to maximize damage
Good additional Defense and Special Defense
Solid Speed for a Mega Pokémon
At level 20 in a Pokémon GO raid, it can be caught with a high CP. With rainy or foggy weather boost, its Water or Dark moves gain a bonus. At level 40 or level 50, with additional Candy, it reaches an impressive maximum power.
Weaknesses and resistances
Thanks to its Water and Dark typing, Mega Gyarados loses its double weakness to Electric but becomes vulnerable to Fairy, Fighting, Bug, and Grass types. Choosing the right nature and distributing EVs carefully is essential to optimize its resistance against these threats.
Best moves for Mega Gyarados
In the main games

In Pokémon GO, Mega Gyarados is available during special days and Mega events. In raids, it excels as a Water attacker with Waterfall and Hydro Pump, or as a Dark attacker with Bite. Its Mega Evolution also provides a damage bonus to other Water and Dark Pokémon on the team.
