Hey i Have an interesting theory Haven't you wondered who luffy's mother is or maybe Grandmother.
Okay There is this one lady who i think is related to Luffy Maybe his mother or maybe his grand mother.
If you have seen all the episodes so far then you know this character.
If you know that lady in Amazon lily.
The former Queen. The old lady. I believe she is the possible mother or grandmother of luffy!
Don't worry I do have reason.
If you remember she Said she had once run away with the person she loved and thus survived her illness which was Love.
And for anyone to reach amazon lily they would have to be pretty tough.
And the marines can reach there so Monkey D. Gramps could have Gone there and he is Quite Tough.
They Still Haven't Shown Who Luffy's Grandmother Is.
And the former Queen Of Amazon lily Does seem like a liable option.
Tell Me What You Guy's Think!
