Don't know from where coby wank is coming from but if I have to guess then it's indirect attempt to downplay EoS zoro and a bad one lmao
Coby as rival is bad take
literally
The term rival can be used in two sense
A) a person competing with another for the same objective
B) or if they are equal
FIrst, Coby and Luffy aren't competing for same objective. Their aims are different. (No explanation needed for this)
Second, They aren't equal as well. Enies lobby Luffy neg diffed Coby and even now Luffy is yonkou level whereas Coby is nowhere near his strength. Gap is clearly huge.
Yes, Coby will become an Admiral but to assume that he will magically grow in strength and overcome such huge gap to match Luffy is naive and overlook key aspect that Luffy will also grow in future and won't stay stagnant.
Another thing is haki. Coby will never have haki as strong as Luffy or you can say atleast against Luffy for two reasons
1)Will power difference
2)Coby is fanboy of Luffy or as conqi says "He is Marine version of Barto"
So, they won't be comparable or equal as well. Therefore, this rival thing is just bad take and bad agenda.
This stands more true for a ultra side chick nobody Helmeppo who will not gonna surpass yonkou level to match Zoro. Just Zoro AdCoC blast would Ko him
Smoker has far better portrayal to match Luffy than Coby ever got but kudos to Oda for being damn good in ruining characters
