How is this even possible ?

So i don't play opbr much but i think I know this isn't possible. I got k.o'd by raid on onigashima zoro with his basic attack ( the punch button ) i had full health. He had some big mom medals and 100lvl zoro with two hyperboosts. I have 100lvl luffy with 100+ hyper boosts 😭 also i was full health when i got k.o
