@Jawahib Hahaha can't believe you just saw it ! Thanks for reading it though ^^ Rest assured, you're not a killjoy, your feedback is very welcomed. Very true. Same thing goes for all other ONE PIECE theories. What you say here is very important and I fully agree with it. But I never actually said that it's Teach himself who controls his brothers' hands and powers. I left this open for speculation. What i meant is that we readers saw Teach in Marineford using both Yami Yami no Mi and Gura Gura no mi. I thought about this for a long time even before posting this theory. What i thought of is that maybe Teach's brothers act accordingly to Teach's will, not because they read his mind, but because they're kinda synchronized with him as twins who were close to each other for a very long time and they know each other well. So for example when Teach goes into Gura Gura stance, his brother who ate the Gura Gura no Mi understands that Teach intends to attack using that fruit, so he uses the power. It might also be some kind of telepathy between the 3 brothers ... I don't wanna go deep into that because i'll sound too far-fetched xD but you never know what Oda will do. I repeat. What you said is very important, it's the key point in this theory and, in my opinion, its major flaw. If i had discovered the way Teach might be communicating with his brothers inside him, then i'm sure this theory would be a " fact " XD I didn't. I gave my opinion on the theories and gave my counter-arguments like when i said that even if a Cerberus eats 3 Devil Fruits then it's still the same human body and if it's some ability of the Yami Yami no Mi then it's also still the same body. I only used the Gorosei's quote as a backup. But this theory isn't about how Devil Fruits are extracted. I don't think i got your point here. Do you mean he's collecting Devil Fruits ? But he's doing that for his crew as well, like in Dressrosa when he wanted Burgess to eat Mera Mera no Mi. Or do you mean he's building a crew of Devil Fruit users ? But how ? His first mate Burgess never had a Devil Fruit and yet he recruited him. Shiryu of the Rain has no Devil Fruit either ( i believe ) ... i don't get why you said he's collecting Devil Fruit users from around the world. More like he's recruiting crewmates and then collecting Devil Fruits for them to eat. I liked when you said " coincidental ". This indeed sounds suspicious. Yami Yami no Mi is the only Logia that doesn't require Armament Haki so that its user get hurt. And also cancels Devil Fruit effects. Moreover, the guy who ate it was able to eat another Devil Fruit. Suspicious. Thank you so much dude. You didn't offend me in any way, in fact i enjoyed reading your answer. Now you know why i considered Teach's internal communication with his brothers as a " major flaw " but not the biggest flaw ? Because this is the biggest flaw for this theory. I'm thinking about it right now. That big fat nerd Teach defected right after eating Yami Yami no Mi. So how come Marco knows about his weird body if what that means is him hiding his two brothers ? But what if Marco meant something else regarding Teach's body, and he thought that the weird body is what made Teach able to eat two Devil Fruits ( but he's mistaken ) ? sounds possible but i don't think so. One thing i wanna add to this regarding Teach's weird body. In Jaya Island, when Teach drank the booze in that bar he hated the taste of it. Outside the bar, when he drank that same booze he loved it.
