This is just a theory but does anybody think that bonneys devil fruit is to do with metabolism? I.E maybe since she has the metabolism of a child she can turn into a child herself and maybe depending on her targets metabolism she can either make them younger if they have a metabolism of a child like her and if they have the metabolism of an older person they will get older. Anyone else agree with then please let me know and if anyone has any other theories please comment back.
