Apoo isn’t vet level. Most of the supernovas are low yc level at least. I’d expect apoo to be able to take snack out, and id bet that drake is already stronger than Jack, and Kidd and Zoro probably push any YC1 to extreme diff or better.
It doesn’t have to make sense, but the supernovas are portrayed as Luffy’s peers.
Luffy has grown a lot but none of them have stagnated either. Most of them would still be challenging for Luffy and Zoro to defeat, especially with the weird abilities most of them have.
