I know this sounds like a silly guess, but I couldn't help but notice the guy on the top left corner of the color spread in Chapter 693. My only guess is that the guy could be Kaido, one of the Yonko(Four Emperors). If Shanks, Marshall D. Teach, and Charlotte Linlin, then I'll bet Kaido must be on the color spread. Do you agree or disagree?
