Luffy had help from Law against Doflamingo. Neither Trebol nor Bellamy did anything significant to Luffy- meanwhile Law literally nuked Doffy's inside lol. Either way, it wasn't 1v1.
Cracker was Nami's help.
Katakuri was Brulee's help. Luffy would've actually died if she didn't help him run away in mirrors after G4 ran out. And even the bitch sister's cheap shot helped Luffy, as he was heavily losing that fight anyway- and cheap-shotting him only prompted Katakuri into giving himself a grevious wound even though he was fresh otherwise. Either way, not 1v1.
Even Hordy was with Shirahoshi and Fukurojo's help.
I guess he defeated Caesar on his own? I don't really remember that fight.
Like, I think Luffy could've won some of these fights by himself, but he literally won, like, one 1v1 post-skip until now... that's a factual statement. I'm not saying he's shit, just stating something that's a fact.
Idk. I'm just correcting someone who said Luffy 1v1'd everyone except Kaido and Doffy.
