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. 4 resistances help offset the weaknesses. With 95 HP and balanced defenses, Gyarados can afford to eat a neutral hit or two.
| Damage | Types |
|---|---|
| 4x (Critical) | Electric |
| 2x (Weak) | Rock |
| 0.5x (Resist) | Fire, Water, Fighting, Bug |
| 0x (Immune) | Ground |
- Only 15 types exist — Dark, Steel, and Fairy are absent
- Ghost has no effect on Psychic (a known bug, fixed in Gen II)
- Special stat governs both offense and defense — no Sp.Atk / Sp.Def split

Y Gyarados Best Moveset
Water moves run off 100 Special instead of the 125 Attack, the format's most punishing stat mismatch alongside Flareon. MoveHyper Beam and MoveBody Slam use the Attack honestly, and Normal damage from 125 Attack is no joke. The move slots work around the type split rather than through it.

Moves List
TMs carry this one. Gyarados learns Hydro Pump and Surf naturally for STAB, but the offensive range comes almost entirely from technical machines. Normal and Dark and beyond give it real matchup play.
