Worst theory I have seen in this forum
Do agree that haki may not be as linear as we'd thought. Since each new usage is revealed over time to us as readers it appears to be a linear track but depending on some talents users could start at what we consider the advanced level before they do the basic level (especially for CoC). Harder to make the same case for the other two since they genuinely do seem to be advanced versions of the same basic while CoC and aCoC usage are not the same at all with aCoC being more like CoA.Yeah man I had a different perspective but I can get behind this sentiment. The world of OP is huge. People level up different skills at all sorts of pacing, including Sanji. Sanji can aCoC but could he consciously blast shockwaves to KO fodder? Can Zoro? Only subconsciously.
I think it is time to redirect our phrases such as 'advanced' because sure, Kaido did say that few people can clad CoC and that statement remains true. What he did not say is the statistic of people who learn that first or second. It looks like some people manifest their first CoC powers by overpowering others with their willpower as we saw with Doflamingo or Luffy with Duval's rhino or whatever that animal was. Zoro and Sanji didn't "skip" this step because it almost seems like they started here and I think this is a notion that, for many people, is very hard to accept. Myself included and this is why so many of us disliked the way Sanji gained CoC but Oda paints a clear picture: people grow in different ways. ACoC isn't really Advanced CoC. It is just the way CoC is used. I'd expect Zoro and Sanji to consciously do some CoC blasts soon, that will be their "ACoC" lol but honestly it shouldn't be framed that way. It should just be known as a different way to use CoC.
But thats just a speculation, we don't know if she has a takeover form for each members of the 9DG.Because Alegria is an amalgamation of all of Tartaros. It's not her just simply taking over but combining their forms and powers into one being. Using its power was a complete drained to her MP in the past. It makes sense why she reserves that form as trump card. On the other hand, Seilah form does not drain as much mp and therefore is smarter to use against weaker enemies. Having a form that uses all abilities at once and lesser forms that utilize only one ability at a time, but drain only a little mp does make sense. She does have the takeovers of the 9DG as she absorbed their souls. She doesn't use them because 1. Mashima has to create a design for said form and 2. Mashima doesn't effectively utilize Mira's potential in Demonic Takeover.
