Suggested by Random Natsu is an incredibly powerful fighter who regularly disregards power levels. The bonds of his friendship are what fuel his power and that makes him a very big threat. Giorno can’t hope to keep up with Natsu so his best bet is to try and cancel his actions long enough to think of a plan. The thing is that Natsu’s motivation can never lower thanks to his friends and you can delay his power, but not stop it. Natsu won’t give up until he’s knocked Giorno out and that’s exactly what is going to happen. Natsu wins.
