Seadra Weakness
Electric and Grass moves hit Seadra for super-effective damage. Its Water typing keeps the defensive matchups simple. With 55 HP and balanced defenses, Seadra can afford to eat a neutral hit or two.
| Damage | Types |
|---|---|
| 2x (Weak) | Electric, Grass |
| 0.5x (Resist) | Fire, Water, Ice |
- 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
