Introduction

Abilities are innate passive effects that fundamentally shape a Pokémon's competitive viability. A single ability can transform an otherwise unremarkable Pokémon into a metagame staple or provide the crucial edge needed to execute specific team strategies.

In Pokémon Polished Crystal, abilities follow modern-series mechanics, enabling deeper strategy through damage amplification, defensive utility, speed manipulation, and field control.
