Supernovas are completely objectively determined by rookie bounty. However sanji was same the generation as the WG. He didn't get 100k as rookie, but now has surpassed most of them in bounty. Do y'all consider him part of the worst gen. I personally do even though he's weaker than all of them and Morgons did not include him in his prediction despite witnessing Sanji in action. Note: The question is more about whether the world will see Sanji at the same level as the supernovas, not necessarily him being directly included in it.
