This is where a member of royalty takes part in battle himself, especially as a commander. This was once quite common, and examples of it can be found from time to time in the present day. It is a favorite of epic and romantic tales and goes back far in the history of literature, back to things like The Iliad. A warrior prince can be a Wise Prince, bravely fighting for his kingdom; he can also be an evil conqueror. While this character always stands a high chance of being a badass.
