How to Get Mewtwo in Red & Blue
Mewtwo Weakness
Type-wise, Mewtwo takes extra damage from Bug. Ghost moves do nothing thanks to a full immunity. Mewtwo's special bulk (base 154 Special) helps absorb special-type weaknesses, though physical moves exploit the lower Defense.
| Damage | Types |
|---|---|
| 2x (Weak) | Bug |
| 0.5x (Resist) | 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

Moves List
TMs define Mewtwo's movepool. The natural moves cover basics with Psychic and Confusion, but the real versatility comes from technical machines giving it coverage across 7 types. That's where the options open up.
