Rivalry (Japanese: とうそうしん Belligerence) is an Ability introduced in Generation IV.
When using a move, Rivalry raises the power of the move by 25% if the target and the Pokémon with this Ability have the same gender, but reduces base power by 25% if the target and the Pokémon with this Ability have opposite genders. If the Pokémon with this Ability or the target is genderless, the move's power is unaffected.
Unless the Pokémon is genderless, Rivalry powers up confusion damage.

Rivalry no longer powers up confusion damage.
Outside of battle
