Best move types to use

Move availability depends on game version and learnset data, so this page recommends move types rather than guaranteed moves.

Counter notes for Gyarados-Mega

• Gyarados-Mega is a Water / Dark Pokémon with 81 base Speed and stronger physical attack (155 Attack). Electric, Grass, Fighting, Bug, and Fairy attacks all work offensively, but safer counters are usually the ones that reduce risk from its own STAB types.
• Gyarados-Mega has several 2x weaknesses rather than a single 4x weakness, so the best counters are the ones that can hit it super-effectively while also reducing the risk from Water / Dark STAB.
• Known abilities include Mold Breaker. This page does not assume ability-specific battle effects, so verify the format before relying on a single counter.
• Avoid counters that are weak to Water / Dark unless they are fast enough to pressure immediately or bulky enough to survive the exchange.
• Gyarados-Mega has alternate forms that can change this matchup, including Gyarados. Check the specific form before relying on this defensive profile.

What not to use

These attacking types are resisted or blocked by the defender's typing, so they are usually lower-priority choices unless they provide a special battle role.

Battle caveats

• This ranking uses modern Gen 6+ type matchups, STAB value, defensive switch-in safety, and base stats.
• Abilities, held items, Terastallization, weather, terrain, and format rules can change real battle outcomes.
• Coverage moves can punish obvious counters, so treat this as type-based guidance rather than a full matchup simulator.
• Move availability depends on game version and learnset data; this page recommends attacking types rather than guaranteed moves.
