Who said anything about luffy being the mc making his hits harder? Dont put words in my mouth annoying asfThat's nothing to base it on since we have no way to compare the impact force of G4 Luffy and Jacks attacks. Just because Luffy's the MC doesn't mean we won't have characters who can hit harder than him. How do we know Jack doesn't have equivalent impact in his hits, Kata was able to match G4? You're basing your assumption of a complete unknown.
