Oda hyped him up. I expected to see him in some arc. I was hoping for an arc similar to Thriller Bark after Dressrosa where Weevil would play a huge role. Imo, Weevil looks more like one of Moriah Zombies than an actual clone.
I was hoping he could be the enemy after Katakuri and before Kaido. Instead, we got Wano and like 4 Power ups because Luffy had to pass from Katakuri to Kaido directly lol.
However, there as and interview where Oda said Weevil Is super cool and has plans for him:
So Oda must have plans for him.
I mean, we now know the Is basically WB's clone now, even though with problems.
As I see It, the CG Is the Natural Place for him to be. He and Buggy are made for each other. Weevil even has kind of a circus theme and he Is dumb enough to follow Buggy's lead (and lies).
That means he'll be in the face for the OP.
