In FireRed & LeafGreen, Intimidate changes the entire equation for Gyarados. The 540 BST doesn't tell the full story. Ranked B-Tier as a wallbreaker. Earthquake with Leftovers is the standard set.

Does Gyarados mega evolve?

Mega Evolution isn't available in FireRed & LeafGreen, but Gyarados does have a Mega form in Gen 6-7 games (X/Y, ORAS, Sun/Moon). Mega Gyarados hits 640 BST.

What is Gyarados weak to?

In FireRed & LeafGreen, Gyarados's biggest threats include Jolteon (Electric) and Golem (Rock), all carrying super-effective STAB moves. Jolteon is the most dangerous since Electric moves deal 4x damage. Only 2 weaknesses means fewer dedicated counters to worry about.

What is the best ability for Gyarados?

Intimidate is what you want on Gyarados. Every competitive set worth running is built with that ability in mind. The alternatives (Moxie) work on paper but Intimidate is what makes Gyarados worth using. Intimidate synergizes with Gyarados's base 100 Sp.Def, letting it soak special attacks as a pivot.

What role does Gyarados play in battle?

Base 81 Speed is workable. Faster than some, slower than many. On offense, Gyarados is a mixed attacker with base 125 Attack and 60 Sp. Atk. Defensively? Enough bulk to take a hit or two. Best used as a wallbreaker.

Gyarados Weakness

Type-wise, Gyarados takes extra damage from Electric and Rock. Watch out for Electric attacks, those deal 4x damage. Ground moves do nothing thanks to a full immunity. 5 resistances help offset the weaknesses. With 95 HP and balanced defenses, Gyarados can afford to eat a neutral hit or two.

Gyarados Guide

In FireRed & LeafGreen, Intimidate changes the entire equation for Gyarados. The 540 BST doesn't tell the full story. Ranked B-Tier as a wallbreaker. Earthquake with Leftovers is the standard set.
Mega Evolution isn't available in FireRed & LeafGreen, but Gyarados does have a Mega form in Gen 6-7 games (X/Y, ORAS, Sun/Moon). Mega Gyarados hits 640 BST.
In FireRed & LeafGreen, Gyarados's biggest threats include Jolteon (Electric) and Golem (Rock), all carrying super-effective STAB moves. Jolteon is the most dangerous since Electric moves deal 4x damage. Only 2 weaknesses means fewer dedicated counters to worry about.
Intimidate is what you want on Gyarados. Every competitive set worth running is built with that ability in mind. The alternatives (Moxie) work on paper but Intimidate is what makes Gyarados worth using. Intimidate synergizes with Gyarados's base 100 Sp.Def, letting it soak special attacks as a pivot.
Base 81 Speed is workable. Faster than some, slower than many. On offense, Gyarados is a mixed attacker with base 125 Attack and 60 Sp. Atk. Defensively? Enough bulk to take a hit or two. Best used as a wallbreaker.

Game Availability

Since debuting in Red & Blue, Gyarados has appeared in 22 titles over 10 generations. Along the way, it received a Mega form in Generation 7, keeping it relevant across different competitive metas.
