Here's a thought
What if Imu is currently in Joyboys body?
Remember back in punk hazard when Law was able to seemingly swap the minds of the strawhats?
What if 800 years ago someone did that to joyboy and imu ?
What if Joyboy was on the verge of winning before the swap occurred
But because Joyboy was injured from the fight he couldn't focus his Haki in order to block it
We'll see Joyboy first and then when we meet Imu in the modern day we'll see him in Joyboys body
