Zen Mode in Pokémon Black & White

Changes the Pokémon’s shape when HP is halved.

Changes Darmanitan's form after each turn depending on its HP: Zen Mode below 50% max HP, and Standard Mode otherwise.

At the end of each turn, Darmanitan switches to Zen Mode when its HP is 50% or less of its maximum, and to Standard Mode when its HP is above 50%. It returns to Standard Mode when leaving battle or losing Zen Mode. This ability has no effect on other species.
