I'm going to save this and post it everytime I see a Lanjicuck post their fanfic parallels that only have one objective, to make Lanji seem stronger than what he really is. :cheers:
Fine by me, I'm not even a Sanji fan.
Pick whichever you prefer more, the facts will not change due to that.
The parallels are obvious and I didnt list even close to all of them.
You choose to ignore them because Luffy doesnt parallel Kaido.
You have no fact and your parallels are laughable. A minimum effort of a review:
2a - Kaido and Zoro are the World's Strongest characters of two different generations.
Zoro isn't the strongest of his generation. Certainly not now, certainly not in the future with Luffy (minimum) around.
1f - Both are the greatest names of their own era.
Big Mom was never the greatest name of her era. Xebec, Roger and Whitebeard, and now probably Kaido, all took that place while she has been a pirate.
1e - Both are Jacks of all trades, masters of none.
Luffy is a haki master (at each level he's beyond Zoro, by the way) plus just has consistently made the fullest out of his devil fruit. Far from a master of none.
2c - Both are hard to kill. Nothing managed to kill Kaido so far and it seems not even Grim Reaper himself will take Zoro's soul away.
Luffy is the one here who consistently bounces back from facing death. We don't even know what the Reaper was. If there's a definition of someone hard to kill that's Luffy.
2f - While Kaido is known as the strongest among land, sea or air, Zoro also has defeated representatives of those 3 domains(Hody, Pica and Alber).
So has Luffy (Arlong and Hody; Crocodile; Doflamingo).
2e - Both have an animalistic theme. Tiger and Dragon.
Everybody in One Piece has an animalistic theme.
Now let's focus on each category separately:
1 - Food lovers.
2 - Drink lovers.
Just some quick alternative lectures on what you assume to be intended parallels:
1 - Wano's villain "had" to be an oni and onis have to be drink lovers. In other words, Kaido and Zoro loving to drink is coincidence.
2 - Luffy is a food lover because of Goku (and probably beyond with a shared Sun Wukong inspiration) while Big Mom is a food lover because of the likely Ukemochi inspiration (goddess of food and fertility); plus many other food references in fairy tales.
3 - Whole Cake Island is Sanji arc and Wano is Zoro arc. Adding food to Big Mom's character reinforces Sanji's role.
On top of that, nowhere in the story has been addressed any comparison between Luffy-Zoro and Kaido-Big Mom on this basis. And this is the problem with focusing on similarities with no further thought: we can connect the dots between virtually anything if we don't go beyond the surface, like you did.
1 - Until now, Big Mom was in possession of the most ridiculous ability and 2 chapters ago, Luffy has surpassed her by awakening into Joyboy's sun god Nika.
No argument supporting that the Soru Soru should be considered the most ridiculous ability.
Apart from the fact that we can make many counterarguments by focusing on the falsifiability of your hypothesis, such as Luffy being the actual Joy Boy while Kaido is portrayed as a failed one; Luffy and Kaido being both mythical zoan users with advanced forms of armament, observation and conqueror's; Big Mom and Zoro both using swords to fight and portrayed behind Kaido and Luffy...; Big Mom and Kaido are both emperors sharing an ally relationship while Zoro is Luffy's subordinate...
Again, making comparisons between these two pairs is absurd: not only yours are weak and simplistic, but counterexamples are found with ease. And more importantly: they're all different characters, no need to reduce them to Zoro cheap wank (which is clearly what you intend).
