Stats & Training
Nothing fancy in Weezing's spread. It leans mixed with Defense out front. And you'll get 2 Defense stat exp per KO for it. Follows a medium-fast 1M XP curve.
It lives and grows by absorbing dust, germs and poison gases that are contained in toxic waste and garbage.
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
In Yellow, Slowbro's Surf hits Weezing for 41-49%. Golem's Earthquake hits Weezing for 81-95%. Pinsir deals 41-49% with Hyper Beam.

For Yellow, the core moveset is Explosion, Sludge, Fire Blast, and Thunderbolt. Explosion leads at 24% usage. Sludge provides reliable STAB damage.
