Slowbro Weakness
Slowbro is weak to Electric, Grass, and Bug. On the flip side, it's immune to Ghost-type moves entirely. The Water/Psychic typing picks up 5 resistances to work with. Slowbro's physical bulk (base 110 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.
| Damage | Types |
|---|---|
| 2x (Weak) | Electric, Grass, Bug |
| 0.5x (Resist) | Fire, Water, Ice, Fighting, Psychic |
| 0x (Immune) | Ghost |
- 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
