World Noble

The World Nobles (Sekai Kizoku, 世界貴族), also known as the Tenryuubito (天竜人, lit. Heavenly Dragon Folks), are the descendants of the twenty kings who destroyed the Ancient Kingdom eight-hundred years ago and established what is now known as the World Government.

About
These are the people who are allowed to live in the Holy Land of Mariejoa. However due to their connection to the World Government, they constantly abuse their power and look down on the people below them, referring to them as commoners. They can be sometimes seen walking around Sabaody Archipelago, but are disconnected to the point that they wear bubbles over their heads to prevent from even breathing the air of the common people. Whenever one appears people instantly bow as not to upset them.

They are first mentioned in Chapter 496.

Culture of the Higher Classes
The Tenryuubito have various rights and privileges not held by many other people in the world. In particular, they are able to buy people, including pirates, who have been captured and put into slavery and their actions are overlooked by the World Government. Their method of discipline is to inject tranquilizers into the slave to stop them escaping. They tend to treat their slaves poorly, making them do excess things and treating them badly when they reach their limits. Although they often buy people from Auction houses, they can make anyone a slave that they choose to. They may have as many spouses as they wish, can take anyone they wish as their spouse off the street and can dismiss them in an instant.

Each Tenryuubito shown so far has been seen wielding a firearm, mostly for shooting people they dislike. It is said that no matter if someone is killed right before your eyes, you should never oppose the world nobles. Those who do are immediately reported by them to one of the 3 Admirals: Aokiji, Akainu or Kizaru. Failure of the Marines is also unacceptable by the World Nobles terms.

To this, the World Nobles show no moral values, no regard to Justice and are free to do absolutely as they wish. They can also be regarded as the very example of how corrupt and absurd the One Piece world is. They also swear anyone going them is going against "the blood of this world creators".

History
800 years ago twenty Kings came together to "build" what is the current workings of the world. Their descendants later went on to became the World Nobles.

In the current storyline they first are seen when two of them, Saint Roswald and his daughter Saint Shalulia, appeared on the Sabaody Archipelago. They were seen upon the fall of the escaped slave Dias. After abusing the slave for his futile efforts to escape, they later appeared at the human auction house. The third member of their family, Saint Charloss, appeared. Having bid 500,000,000 on the mermaid Camie, shutting all other bidders out, Luffy and the Rosey Life Riders appeared. Hatchi attempted to stop Luffy from causing an incident, but was shot by Carloss. For his efforts, Luffy punched Charloss, knocking him out.

After witnessing his son being assaulted, Roswald drew out a gun and attempted to kill Luffy. Roswald called out for an admiral while guards entered the auction house and tried to stop the Straw Hat Pirates. He was knocked out when Usopp fell on top of him. His daughter Shalulia attempted to kill the fish they were after, but Rayleigh knocked her out with Haki before she could kill Camie.

After the World Nobles were all knocked out, word was put out they had been taken hostage by the Straw Hat pirates, with help from the Heart Pirates and Kidd Pirates who had been mistaken to be co-operating with them even though they had just been by-standers.
