Whitebeard: WSM due to world ending Gura powers
Kaido: WSC due to dragon devil fruit
Linlin: built her empire using the soul devil fruit
Outside their devil fruits, there are barely any notable feats against top tiers using base mode, you can only make a case for Whitebeard against Roger
Kizaru has actual cqc feats against Nika amd Rayleigh, two yonko killers, without direct usage of his power
We have Kuzan matching Garp the fist
Fujitora with a supreme blade and Greenbull with a black blade
Admirals in base are leagues above the yonko
