Lmao you gotta stop this shit. If Kuzan had Garp punching power, he would have went
fist to fist with Garp. Him punching Garp in the face and sending him flying, is shit Luffy did pre-TS.
When Garp and Chinjao threw down for a duel they both clashed with their attacks. Same for Roger and Whitebeard, Luffy vs Kaido. What Oda did with Kuzan is just sly shit.
I'll give Kuzan more credit for being able to eat a Garp fist.
