Rivalidad

“Si el objetivo es del mismo sexo, su competitividad le lleva a infligir más daño. Si es del sexo contrario, en cambio, el daño será menor.”

This Pokémon inflicts 1.25× as much regular damage against Pokémon of the same gender and 0.75× as much regular damage against Pokémon of the opposite gender. If either Pokémon is genderless, damage is unaffected.
