Lu

Luffy would of won all of these either way eventually plus he out smarted enel which is why he won plus Luffy is made of rubber so all of enels attacks would fail except for lightnings heat

It's not the gomu gomu fruit it's the human human fruit model nika I wanna point that out also it's not really a paramecia it's more of a mythical zoan everyone usually never notices that and that gets annoying honestly also pretty good otherwise

Yuta cooks yuji in a one v one reasons yutas technique allows him to copy cursed techniques and rika could just help him avoid yujis domain and yuta could copy almost every ability in jjk plus if he eats a sukuna finger he could also use sukunas technique allowing him to absolutely cook yuji in a 1v1

As the show says he could turn anything into rubber so theoretically he could turn his allies to rubber to dodge attacks and gain immunity to a lot of attacks and he could just make everything around him to rubber to bounce his enemies to immobiles them to the point they can't attack so it's a bit harder.
