User blog comment:Apoelpaoole/X-Bracelet on Mihawk-Doflamingo-Blueno/@comment-4679046-20130317072651

These guys have nothing in common really. Doflamingo is/was a king. I can see Mihawk being a king (his manners show his origin) but i doubt Blueno is anything similar. In terms of skills....Dofla has a devil fruit + haki (conquerors- Haoshoku included), Blueno rokushiki user, Mihawk top swordsman + haki. It's possible it is given to people that come from a certain island. Who knows, maybe Mihawk was a lord in Dressrosa and blueno was a spy of Dofla who was from Dressrosa. Nobody really knows except for Oda, and it is possible we never actually learn if he drew this by chance and the reason.
