User blog comment:Xyriel 14/Supernovas as New Shichibukai Candidates/@comment-3119203-20121014193501

Drake - Why leave the Marines only to dive back in? I doubt he would want to do that....

Bonney - Not strong enough. If anyone hears how she got taken out by Teach, then there goes her reputation. Remember, the Shichibukai is 50% power and 50% name.

Bege/Urouge - There's chance, but we don't know a lot. I don't think either of them have the strength to make is a Shichibukai.

Overall, with Law as one of the Shichibukai, I don't think we'll see another Supernova in that spot. Who knows though.
