Current The Yonko Vs Current Four Heavenly Kings
-All characters bloodlusted and Serious
-No holding back
-Win by death
@taichokage: In the current arc, Zebura is using his sound shields to protect 100 million people while a war is going on. Also Zebura and Coco can combine their powers to use poison sheild armour, making the four kings untouchable if they used it on themselves. Plus they have many more powers, which I don't think anyone apart from Logias can combat in OP.
I don't think you are wrong. Toriko in general is rising above the HST rapidly in power, and the Heavenly Kings would be top tier in One Peice. If not now then in the relative near future they might be of the caliber to solo One Piece together. I'm just throwing it out there that we don't know Kaido's, Big Mom's or Shanks's abilities at all other than Haki. Blackbeard we know some of but apparently he's been stealing other fruits. You are almost certainly right but... Ok I guess it's safe to say the Kings win, but there is a chance that it might not be so.
Zebra might be able to solo right now....He has a feat that puts him at around mach 50 according to othus12, his destruction ability would be more than enough to destroy One Piece characters, logia intangibility or w/e off of course
