Aren't the hashmarks just there so OP isn't 18+?
I mean her big head looks like a normal head and I would say making a big head out of small ones is the hardest one to pull off, yet her face and head look perfectly normal.
No abnormalities like hashmarks there heh.
Well, Robin's fruit is vage. The name of her fruit just implies she can bloom something but it doesn't even say anything about body parts.
Also Robin fusing limbs (not just making them sproud next to each other and stacking them up) seems more like a new fruit than big clones of them. Also Black Maria saying it takes a lot out of her also implies the latter.
Robin never seemed to use up much energy whenever using mil fleur attacks but since this one might be a pure, big clone it takes a lot out of her.
Why would Oda bother giving a number with every other attack but all of a sudden he is like "I won't bother this time". I mean he did bother just a page before demonio, making Robin say mil fleur gyojin karate.
And like I said the word Demnio replaced the number or else there would be 2 fleur in her attack name.
For example "mil fleur demonio fleur". That sounds off.
