Psychic/Steel damage taken

¼×	Psychic

Best types to use against Psychic/Steel

To beat a Psychic/Steel Pokémon, use Fire, Ground, Ghost and Dark moves: they deal 2× damage. Do not waste turns on Poison (0×), Psychic (¼×), Normal (½×), Grass (½×) and Ice (½×).

Psychic/Steel and Steel/Psychic are the same typing: in battle the order of a Pokémon's two types makes no difference, so a Steel/Psychic search lands on this page too.

Going the other way, Psychic and Steel moves between them hit Ice, Fighting, Poison, Rock and Fairy super effectively, but Steel takes reduced or no damage from both.

11 Pokémon have the Psychic/Steel typing: 8 species and 3 alternate forms, first appearing in Generation 3 and spanning 4 generations to Generation 9.

The highest base stat total is Mega Metagross with 700; the average across the group is 539.

Abilities that change Psychic/Steel matchups

Heatproof halves damage from Fire moves (Fire 2× to 1×). Held by Bronzor, Bronzong.
Prism Armor cuts super effective damage by a quarter (Fire 2× to 1.5×; Ground 2× to 1.5×; Ghost 2× to 1.5×; Dark 2× to 1.5×). Held by Dusk Necrozma.
