Found this elsewhere, and thought it was interesting.
! @Trolling:
! > I have decided to place my bet on my own theory that Big Mom's powers are based off of Digestion.
You can already see her acidic properties in her saliva from the picture. (Its melting the floor). Meaning
- Her spit is acid
- she Has a super Digestive system
I support this theory because In fish man Island She was claimed to be reciving ten tons of candy. Meaning that she must be able to proccess all of that quickly.
Thinking about how she could be the choji of One Piece lets do some math
Assuming Bobbins is a normal size human. Big mam is roughly ten times his size. The proportions of her body mean she has a large body fat ratio increasing the caloric energy her body holds
1 calorie = 4.89 joules
Assuming her body fat ratio is 50% (which is extremely an understatement due to her proportions)
That means if she was a normal sized human (Who has about 110,000 calories in their body) She would have around roughly 330,000 because all of the energy stored in bile. (Still an understate ment)
That means she should assuming she can digest fast and due to her being ten times that size
330,000 x 10 x (4.89 Joules/1 calorie) =138,072,000 joules of energy
For those who didnt read that math, let me sum it up 138,072,000 joules of energy could be extracted from her body at any point due to her digestive system being on overdrive. Which is a bit less than the nuclear bombs that were dropped at hiroshima. which were 800,000,000 joules of energy.
So My theory is That Big mams DF (or not even df just mastery over the human body(could you imagine that being a learnable fighting style)) Is that she gets fat and metabolizes all that energy become a turbocharged Digestive woman.
Which with her size and what she has shown would be comparable to a nuclear bomb going off.
EDIT: Futhure simplification of analazysis. My theory is that she has the ability to digest all the energy in her body. And use it at once making herself an energy powerhouse. Which would involve rapid wieght lose and psuedo Supersayain quailites. Her power doesnt need to be a DF as characters have mastere body control by itself. Her mastery would be on digestion and drawing quick burst of large sums of energy.
