Weezing Weakness
Type-wise, Weezing takes extra damage from Ground, Psychic, and Bug. Weezing's physical bulk (base 120 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.
| Damage | Types |
|---|---|
| 2x (Weak) | Ground, Psychic, Bug |
| 0.5x (Resist) | Grass, Fighting, Poison |
- 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
