Buggy and his prowess could play a significant role in the culmination of One Piece.
One Piece is a renowned saga with countless theories surrounding its mysteries, sparking curiosity among readers. The hypotheses range from the One Piece treasure, the Void Century, to the World Government's intentions. One particularly intriguing theory involves the potential of the clown Buggy in the story's conclusion.
Buggy consistently assumes the role of a humorous character, but his journey to becoming a Warlord is noteworthy. It is evident that Buggy has been present throughout the entire narrative, indicating he could play a crucial role in the conclusion of One Piece, especially when considering the power and awakened Devil Fruit abilities he possesses.
The theory about Buggy's Devil Fruit awakening
Buggy is one of the initial antagonists that Luffy faces. He appears right from the beginning of the series with an extensively explored past. Therefore, fans speculate that, similar to the character Mr. Satan in Dragon Ball, Buggy could play a vital role in the climax of the story.

Another reason supporting this hypothesis is Buggy's remarkable advancement, leading him to become a Warlord and rumored leader of the new organization Cross Guild, with support from Mihawk and Crocodile. Additionally, there are rumors that Buggy's Devil Fruit was originally intended for Luffy. This clue may hold special significance in the narrative crafted by Eiichiro Oda.
Several theories propose that Buggy's Devil Fruit is connected to a divine entity, similar to Luffy's Gomu Gomu no Mi being linked to the Sun God Nika. Furthermore, the requirement for Buggy to keep his feet on the ground to use his Devil Fruit abilities seems to allude to Pangea Castle and the ancient Pangea on Earth, creating a plausible connection to the divine.
This hypothesis suggests that the awakening of Buggy's Devil Fruit may play a decisive role in the conclusion of One Piece.

Author Eiichiro Oda previously assigned Buggy a comedic role, similar to Mr. Satan in Dragon Ball. This approach indicates that, despite possessing potential, Buggy may not achieve significant prominence in the story. With numerous diverse characters and a complex plot already in place, Oda may choose to focus less on Buggy and maintain the character's light-hearted and humorous role.
However, it is impossible to completely exclude Buggy's involvement in the latter part of One Piece. Nevertheless, it is advisable to avoid setting overly high expectations.
