This is just my own opinion. The last one is luffy at the "END OF SERIES". I think Luffy will inevitably surpass Joyboy because he will accomplish what he hasn't, however, he has only just awakened the powers of Nika. It will take him some time to fully master it and a bit more to surpass him.
Peaple know that joy boy have a straw hat in shank have a straw hat to I'm cumfuse why I think shank in joy boy are best friend I quest do I'm right in also joy boy really Ganna eat the gum gum fruit but then Luffy eat it so joy boy save Luffy to life in give Luffy to aweken his fruit 👇
Joy boy is the founder of nika when he died he's fruit was stored and shanks stole it and Luffy ate it so he become joyboy when he activities gear 5 he's only called joyboy because the gear 5
Bro imu is stronger imu litterly got his joy boys hat and u can even search it up and sorry for complaining u work a lot sorry I'm just trying to say ❤
The last one was amazing and confusing becoz luffy our boy is joyboy only vs the old joyboy i think old one will becoz he have more experience and he have already been the the strongest and being defeted by one people imu sama but luffy have been defeted by many people so old joyboy will win not luffy our boy
