Types

The 17 types and how they match up in battle.

Differs from the mainline games

pkmn uses the Gen 3 type chart. There is no Fairy type, and Steel resists Ghost and Dark moves (from Gen 6 on, those hit Steel for normal damage).

Attacking type down the side, defending type across the top. Blank cells are ×1.

Whether a move is physical or special depends on the move, not its type (as in Gen 4 and later); each move page shows its category.
