User blog comment:Epzilon/The Eleven Supernovas come to Bleach?/@comment-1493741-20150924103631

How its achieved: Personally, I suggest that it shouldn't follow One Piece's approach. The Eleven Supernovae as I understand it, are all chosen because they have a bounty of 100,000,000 and up which classifies them as presenting a significant threat to the world. In this case each Supernova has no real affiliation with the others, they simply hit a point where they enter the radar of an organization that classifies them as dangerous (The Navy, I presume). If the idea here is to bring disparate individuals together, then the title what it implies should help facilitate that. As an example (And one I wouldn't actually suggest using) the title could be along the lines of "Those With Potential", a group of individuals actively seeking self-improvement and show palpable signs that they could surpass the Yonkō in time. Which makes them dangerous at the same time, I suppose with different reasoning at least.

How its Bestowed: I'd suggest that Central 46 be the ones to bestow this title on its prospects. To Central 46 it would mean they're keeping an eye on these individuals, because they are dangerous and could cause an upset to the balance of Soul Society. But, at the same time, the title would be misinterpreted, the public aren't privy to the knowledge of Central 46 so when this title first came about, especially given that its applied to specific and skilled individuals, the public would see it as an accolade instead.

The Title's Origin: As a mechanic used by Central 46, it has likely always existed as a means to identify those with the means to directly affect the balance of Soul Society on their own. This would encompass a lot of characters that already exist, both Fanon and Canon (Urahara, Aizen, Kurosaki, Yamamoto, the Yonkō all come to mind) to set a precedent for whatever sits in the current generation.

How it Ties in: A side-arc could be devoted to addressing these individuals. Assuming the previously discussed idea of Super Christian Central 46 Member is still planned to be included, he could be seeking them out to bring them into his fold as a means of vastly accelerating his plans.
