Secret Power deals damage and has a 30% chance of inducing a secondary effect on the opponent, depending on the environment. The move's animation also changes, reusing that of a specific attack for each terrain.

When a Pokémon is holding Normalium Z and uses its Z-Power, Secret Power turns into Breakneck Blitz and has base power 140.

In Ruby, Sapphire, Emerald, Omega Ruby and Alpha Sapphire, Secret Power allows the user to create their own secret base when used on weeping willow-like trees or indented walls.
