Let's start with Bruce Wayne, as the leader of the most powerful empire.
Richard "Dick" Grayson, a prince and considered a leader of the Western Provinces, was a charming man with many lovers, both male and female.
Jason 'Peter' Todd, the second-in-line prince and leader of the Eastern Cities, was hot-tempered and sometimes dangerous. He had killed many people, and while he was dangerous, not as much as the youngest, some say he had fewer mistresses than Dick.
Timothy Jackson Drake, the third in line to the throne, is a leader in resource and financial affairs, or perhaps politics. He doesn't focus on having mistresses, but he's certainly not one to be underestimated.
And the last dangerous one, Damian Wayne, or Damian al Ghul, the youngest prince, but he's the leader of the army and also very cruel and dangerous... and of course, he has many concubines, almost as many as or even more than his older brother Dick.
