VS
I was thinking about this scenario,but suddenly i was reminded of this panel
He was an subject before the final successful version i.e. Natsu or rather END in this case,so logically END should be stronger than Larcade,but there again END's performance wasn't that good against Gray and Erza.But even then counterarguments can be given that Gray had Slayer advantages and Erza stopping END's punch and being burned isn't anything degrading END's power because Erza was able to survive nukes from pretty serious and bloodcrazy Irene.So who do you think wins this?
Note Natsu can only use his END powers and not his DS powers,Larcade can use every abilities he has shown.
