I hate Nika. I like G5 and the looks and powers but I hate Nika.
Luffy was never hinted to be a Zoan. Nika was never hinted in the story before Wano ( anyone honest knows that the god in skypedia was something else entirely) and its presence is warping the manga in disgusting ways. The changes in the story to fit this shit idea made the manga worse.
Before, there was some reasoning for why people could follow the WG and why they had some heroic characters. Now, every single high level marine is a piece of shit at best. Not only that but, before Nika, there was actually a good development in the threat of the SH crew and how they slowly got more and more attention from the WG. Now, the WG look like a bunch of incompetent fools that could have captured Luffy way earlier had they had a single functioning brain cell.
Nothing in G5, as show, needs the fruit to be a zoan. It works like a paramecia awakening in everything, including the part of letting the user tired. Let's ignore for a moment that Luffy is the shittiest zoan user ever (unable to leave hibrid form), the only feature of zoan awakening that was mentioned was how amazing their stamina was. From the ID guards, to Lucci and Kaido, every zoan user has show great stamina. Except Luffy, since every single ''form'' (G2, G3, G4 and G5) actually had drawbacks to limit their extended use. It was clear that it was designed to be a paramecia awakening but was changed because wano was so shit that it needed the hype to boost sales.
And since Oda created this ''god'' without warning, he now is overcompensating and making everything in the world connect to Nika. And One Piece is worse because of it.
Ok, rant is over.
