Dawg Usopp isn't even that physically strong. You gotta be trolling lmaoWtf, I just told you Ussopp would kick him. Law just needs his fingers to use his gestures. His palms will cover his ears and all fingers will be free. Zoro would just put his hands behind the bladeIf you covered your ears, your hands wouldn't even be in position to get cut. There's not a "might" for Luffy. It's a guaranteed win. How strong could Apoo possibly be in close combat? Once you get close to him, you can probably stop covering your ears too. Every time you punch him, he'd probably stop making any other sounds than those of pain.
Zoro keeping his arms behind the sword is still incredibly cumbersome, and he can't generate the same force with just his neck. As for the last part, we literally see Kid get close and Apoo strike back while Kid is still in close range.
