Fellas, I have cracked the code! Gather around and watch an unparalleled display of Future Sight!
We just got confirmation for what we suspected for a long time -
Rocks is Blackbeard's father.
However, the man who wanted to be the king of the world not only has a similar but an identical wanted poster as another man who wanted to be the king of the world, the legendary Buggy-senchou whose age is fitting to be
Rocks' 2nd son.
But wait, there is more!
Look at this!
The Jolly Roger of Rocks is a flaming skull which I thought refers to Rocks himself being a user of Mera no Mi.
However, even if that was right, it is not relevant to present-day events so there's gotta be something more to it...
Ladies and gentlemen, I give you the
3rd son of Rocks D Xebec - The man with the burn scar!!!
Just look at the Jolly Roger of Rocks - a flaming skull with a scar under his eye, clearly hinting at the man with the burn scar!
