With Who's Who being a former CP9 member, now I'm wondering if there is another reason why Who's Who wants to become an All Star.
In the beginning of the video, you can see the "Beast Pirates" recruiting the "would-be gifters" of the crew too.


Seriously though, it's could add some enticing potential to Who's Who's and Kaido's characters based on why he joined Kaido. It creates an curious parallel with him and Drake which I wonder if Oda will explore further too, it makes that incident with them beforehand all the more interesting too.
I wonder if he was given his DF for joining Kaido's crew too? Such a powerful DF at that? It seems oddly powerful for a former CP9 member to have, given the current CP9 only had "regular zoans" and I expected CP0 to be the ones who have mythical and ancient zoans instead.
