Was reminded of Oda talking about the possible origins of the Jolly Roger in Chapter 2. Thought it might tie into Imu.
In Chapter 2 Oda talks about the Jolly Roger possibly going back to the term "Old Roger" refering to the Devil. This is obviously interesting since a major antagonist of One Piece is the Devil and he features a symbol with 2 crossed femur bones on his cape. Though it looks very minimalistic compared to actual Jolly Rogers.
There might be a parallel here where a possible origin of the Jolly Roger in the real world is a term for the Devil and in the One Piece world the origin of the Jolly Roger could possibly be a mark of the devil. It is possible that the Jolly Rogers of modern times are based on Imu's symbol (Could be a mockery of his symbol started by Joy Boy)
(This post is not saying Oda foreskinned the Devil being a main antagonist in Chapter 2)
