I believe all ancestors of the D. Clan members were from joyboys crew. Their descendants who inherited their will would bring about new dawn of the world
I like to believe that Toki time traveled from the void century with Ryuma, got separated some 400 years later and that’s how Ryuma is speculated to be ~400 years old according to the wiki. Joyboy would need a swordsman after all (if he was really like Luffy). And it would be a funny joke: just like Zoro, Ryuma always gets lost and ends up 400 years between the void century and current century 😂
I believe that Sogeking was a real person who lived during the Void Century and was a part of Joy Boy's crew. I also believe that Sniper Island was a real island which was located at the center of a heart-shaped archipelago.
One thing I haven't heard mentioned is the possibility of there having been another Joyboy 200 years ago. Since the ancient iron giant gets powered by Joyboy's heartbeat, unless he has another power source then Joyboy had to be alive when he attacked the holy land.
Could it be that Joy Boy staged a gigantic war against the conditional Imu, to which all of Joy Boy’s allies were supposed to come, but for some reason they didn’t come (for example: they were deceived), for which they all apologize.
