Psyshock is a damage-dealing Psychic-type move introduced in Generation V. It has 80 base power and 100% accuracy, with 10 to 16 power points.

Psyshock uses the target's Defense instead of its Special Defense to calculate damage. Otherwise, it is considered a special move: it uses the user's Special Attack stat, activates Mirror Coat and Maranga Berry (as opposed to Counter and Kee Berry), has its damage reduced by Light Screen (as opposed to Reflect), etc.
