Harden (Japanese: かたくなる Stiffen) is a non-damaging Normal-type move introduced in Generation I.

Effect

Harden increases the user's Defense stat by one stage.

If powered up by a Normalium Z into Z-Harden, the user's Defense rises by another stage.

Harden can be used as the first move of a Pokémon Contest combination, causing Double-Edge, Protect, Rollout, Tackle, and Take Down to score double the normal appeal if used in the next turn.
