Before the timeskip, the combined bounties of all Eleven Supernovas equal to Beli 2,152,000,000, the highest combined amount of any known group. It is currently unknown what it is post-timeskip. With the information revealed so far, the collective amount is at Beli 3,430,000,000.
Of the Eleven Supernovas, all but two (Roronoa Zoro and Killer) are Devil Fruit users as well as captains of their respective crews.
There are four members who can use Busoshoku Haki: Monkey D. Luffy, Trafalgar D. Water Law, Roronoa Zoro, and X-Drake.
Monkey D. Luffy is the only known pirate of the Worst Generation that is able to use all three types of Haki.
Three members of this generation are confirmed D carriers, Monkey D. Luffy, Marshall D. Teach, and Trafalgar D. Water Law.
Capone Bege is the only known pirate of the Worst Generation to be a parent.
Zoro and Killer are the only members in the group who are not captains.
Four members of the Supernovas have bounties which tie: Luffy and Law at Beli 500,000,000 each and Hawkins and Zoro at Beli 320,000,000 each.
Aside from Killer and Luffy, all the others were named after real life pirates or privateers. While Oda did not intend it at the time, Luffy has a similar naval term via a “Luff”. This leaves Killer as the only one whose name has no link at all to any sea-based term or name, and Oda admitted in an SBS he was given his name out of pure laziness.
Oda drew of ten of the Supernovas (leaving out Zoro) after the two-year timeskip. Blackbeard is also left out of such a depiction.
In 72 Volume SBS, Oda drew the Eleven Supernovas (except Monkey D. Luffy and Roronoa Zoro) as opposite gender. Blackbeard was drawn as a female along with the rest of Shichibukai in 76 Volume SBS.
In the SBS of Volume 64, Oda drew the Eleven Supernovas (except Monkey D. Luffy and Roronoa Zoro) as children. Blackbeard was depicted as a child along with the rest of the Shichibukai in the previous SBS.
