I have a theory on how Pokemon with more males than females in their species work to get mates. They make themselves presentable and offer gifts to their crush in question, as well as showing off their strengths. They will only act submissive when giving gifts. If there's a rival male, they will fight. The female will choose the one who fought valiantly, no matter who lost or who won. Works literally the same when reversed, with females fighting for the males attention, if there are more females than males in the species.
