Uh Oh Batman’s decided to cross the rubberman. Too bad Batman’s never fought a rubberman. Batman will be trying all of his kung fu moves but Luffy will be able to take it and than some. Luffy will use his famed Gum Gum Punch and send Batman flying. Luffy wins

didn’t luffy ever fight a guy named batman on one piece
I’m not sure but that sounds sorta familiar
This must be a joke, most incarnations of Batman lack the skills and talent to even touch Luffy. What’ll be up, Padme Amidala vs. Aunt May Parker? A Chilean Recluse vs. Sharptooth? Dopey the Dwarf vs. A Mind-Flayer? And last but not least, Morrigan of Korcari vs. all the Backyardigans?/S
Yeah Batman’s not going to be doing much of anything here. Luffy’s just a lot more powerful and his stats all around just have this in the bag
