Summary: Multiplies moves' base power by 0.75 if most opponents are of the opposite sex, or 1.25 otherwise, ignoring genderless opponents.
This Pokémon is intensely competitive and can't stand to be outdone by anybody--and certainly not one of its closest rivals! If in battle against a Pokémon of the same gender, Pokémon with this ability will be goaded into showing off a bit, performing more powerfully than they ordinarily would. As a result, the base power of all their damaging attacks is multiplied by 1.25 if the number of opponents of the same sex as the Pokémon with rivalry is greater than or equal to the number of opponents of the opposite sex as the Pokémon with rivalry. At the same time, Pokémon with this ability have somewhat of a soft spot for Pokémon of the opposite sex, and will be too distracted by them to fight as effectively when they're around. As a result, if the number of opponents of the opposite sex of the Pokémon with rivalry is greater than the number of opponents of the same sex, the base power of all this Pokémon's damaging attacks is multiplied by 0.75 instead. If all opponents are genderless, this ability has no effect on the Pokémon's power.
