I know, that's why I mentioned everything I wrote is pure speculation. I just want to start I blog to get people's ideas of future movies.

To be honest, when I made up the Yushinnaga it was inspired from H.P. Lovecraft's Cthuhlu who rises from the ancient city of R'lyeh. The other characters are just made up.

Just like how many of Oda's works are inspired off of different medias.
