These Killer votes are hilarious, he'd not even best Jinbe.
Killer expresses shock at Kaido being cut, a feat even Scabbards can replicate. At no point he was able to cut Kaido, it was his hax that helped him. Once. Off guard, and it isn't a direct AP feat. Blow for blow, he'll need to overpower stronger guy in 1v1.
Imagine him in place of Zoro rn, he'd get ragdolled lol. King not only tanked post Enma training Rengoku, he's overwhelming a guy with much higher AP than Killer. Killer, he's not on top Commander level. Not even close. Maybe Jack, because he's considerably behind and shitted on.
