Nah, BB fans are just looking for crumbs to cope and seek validation from others and wherever they can so that BB can be the ultimate villain. What's clear from following this plot is that the big problem has always been Imu, and that he continues to exist today. And that both Joyboy (Luffy/Rocks) and Davy Jones (Xebec/BB) have been other alternate forces that have tried to stop him but have failed.
Only this time, the outcome will obviously change. But everything points to Imu being the great enemy that the entire world needs to defeat in different ways.
Come on, the writing is on the wall here.
How many times have we seen people say that Imu will be dragged off the throne and that Teach/Davy Jones is the true ruler of the world? Do you really think Teach will fail where his father failed?
In these types of stories, they're always written so where two people from the past failed, their descendants will finish the job for them.
That's true for Luffy, and it'll be true for Teach. They're the characters who were specifically shown to be a parallel to Roger/Joyboy/Nika and Xebec/Davy Jones for a reason.
