@Jwuak Grid overcomes named boss fights because he's overgeared. He is still overly relying on his being overgeared to beat boss fights. When Grid faces human opponents that can also solo boss fights, his overgeared status isn't as meaningful which is what Kraugel is proving.
Kraugel literally just lost a fight after giving it his all with Piaro. He may have been healed, but his gear is still damaged which he has to be mindful of which is why he unequipped his gloves and his stamina was low after the fight with Piaro. Kraugel would have mopped the floor with Grid without even trying if he was truly 100% when he started the fight.
