てきおうりょく (Adaptability)

Adaptability enhances the same-type attack bonus (STAB) from the standard 1.5x multiplier to 2x, making the Pokemon's matching-type moves significantly more powerful. This straightforward but potent boost rewards Pokemon that rely heavily on moves matching their own typing.

The ability is particularly effective on Pokemon with high offensive stats and strong STAB options. Crawdaunt, for example, benefits enormously by hitting extremely hard with both Water and Dark-type moves. Porygon-Z can leverage it alongside its massive Special Attack to deliver devastating Normal-type attacks like Hyper Beam or Tri Attack.

Adaptability has no effect outside of battle and does not interact with any weather conditions, terrain, or other field effects. It simply amplifies STAB damage whenever the Pokemon uses a move that matches one of its types.
