Since Rocks D. Xebec’s appearance in One Piece, a theory has been circulating online that he might be Buggy’s father. While the story has confirmed Rocks as Blackbeard’s father, certain traits of Rocks have led fans to believe he could also be Buggy’s dad.
This speculation gained traction after @pewpiece shared the official colors of Rocks D. Xebec on X. The colors reveal that Rocks’ hair and facial features bear a striking resemblance to the clown Buggy. If true, this would bring a major twist to the storyline.
Official colors of Xebec highlight Buggy’s similar appearance

The recent flashback of Rocks D. Xebec in the One Piece manga ended with his defeat by Gol D. Roger and Monkey D. Garp. Throughout the flashback, there was no mention or hint linking Buggy to him. Still, fans believe these two characters share a connection that could change the story significantly.

A recent post by @pewpiece on X revealed that Rocks D. Xebec has blue streaks in his hair, and although his face looks intimidating, it shares some features with Buggy.
Moreover, these blue streaks suggest that Buggy’s blue hair could have originated from these highlights in Xebec’s hair. This unusual similarity is the biggest clue hinting at their connection, and fans hope Eiichiro Oda is slowly building toward revealing Xebec as Buggy’s father.
This would also create a link between Buggy and Blackbeard, two of the most important characters in the current One Piece storyline. Such a connection would add new meaning to Buggy, making him more than just comic relief but a character who reached a high status not through special powers but pure luck.
It makes sense for Buggy to be Xebec’s son in One Piece

Oda’s hint that Buggy might be Xebec’s son is the spark behind many fan theories, and looking at the story, this idea fits surprisingly well. Buggy has been a key character in One Piece from the start, but he hasn’t contributed much to the plot. His progress and achievements have mostly been due to sheer luck or coincidence.
The only detail about Buggy that isn’t coincidence or luck is that he was once a member of Roger’s pirate crew, which destined him to be an important part of One Piece’s story. However, he lacks the kind of power or influence that would make him an authoritative figure or one of the world’s strongest pirates. So, if Oda establishes a link between Buggy and Xebec, it would add depth to Buggy’s character.
Buggy’s coincidences and fate would make much more sense if it’s confirmed that he’s meant to be part of something bigger. Otherwise, he would remain just a comedic character who achieves success undeservedly.
