I was just re-thinking possible theories of Monet being a Devil Fruit user and I started to wonder, couldn’t Monet be a Logia Devil Fruit user? The Yuki Yuki no Mi? She could be disguised as the snow falling on the frozen part of Punk Hazard when she listened in on what Law and Luffy were discussing. Monet is potentially a “snow-woman” (“Yuki-Onna”).
Just a thought, we now know that Madara awakened his Rinnegan before he died in the past, what if he ended using the “Creation of All Things” jutsu which the Rikudou Sennin used to separate the Juubi, to create Tobi?
