what is mewtwo weak against

Mewtwo is weak to Bug , Ghost , and Dark type attacks in the main Pokémon games and in Pokémon GO.

Quick Scoop: What is Mewtwo weak against?

  • Bug-type moves (like X-Scissor, U-turn, Megahorn).
  • Ghost-type moves (like Shadow Ball, Shadow Claw, Hex).
  • Dark-type moves (like Crunch, Dark Pulse, Foul Play).

Story-style example:
Imagine walking into a raid or big battle and seeing that intimidating Mewtwo on the other side of the field. If you show up with Psychic or Fighting types, it shrugs off a lot of hits, but the moment you send in a Dark-type like Tyranitar or Hydreigon spamming strong Dark moves, you suddenly flip the script and Mewtwo’s “unstoppable” aura cracks. The same goes for powerful Ghost attackers like Gengar or Bug specialists like Scizor, which can turn a scary fight into a very manageable one if you play your type matchups right.

Type chart basics (mini-section)

Mewtwo is a pure Psychic-type Pokémon, and pure Psychic has these core weaknesses and resistances:

In practical terms, that means:

  1. Use Bug, Ghost, or Dark attacks to hit Mewtwo super effectively.
