Buggy's strength in One Piece is a subject of much debate among fans, but the consensus is that while he is not among the top-tier fighters like the Yonko or their strongest commanders, he is far from weak and possesses notable abilities.

Buggy's Strength and Abilities

• Devil Fruit Power: Buggy has the Chop-Chop Fruit (Bara Bara no Mi), which allows him to split his body into pieces and control them independently. This makes him nearly immune to cutting attacks, even from powerful swordsmen like Mihawk, who cannot slice him despite his skill

• Combat Skills: He has demonstrated the ability to fight and survive against strong opponents, including during the Impel Down arc where he held his own among formidable prisoners and survived the Paramount War

• Survivability and Cunning: Buggy's real strength lies in his survival skills, brains, and cunning rather than raw power or Haki. He is known for his ability to avoid death and manipulate situations to his advantage, which has kept him alive and influential despite his cowardly nature

• Potential and Willpower: Some fans theorize that Buggy has untapped potential, possibly related to his past as a member of Gol D. Roger's crew and his connection to powerful figures like Shanks. His current weakness is often attributed to a broken will or lack of confidence, suggesting that if motivated, he could become much stronger

• Leadership and Influence: Buggy's rise to become one of the Emperors of the Sea (Yonko) is often seen as a result of luck, charisma, and the ability to gather strong subordinates rather than sheer strength. His leadership makes him a significant figure despite his comparatively modest fighting abilities

Summary

Buggy is stronger than the average pirate and has unique abilities that make him difficult to defeat in certain ways, particularly against cutting attacks. However, he is not on the same level as top fighters like Luffy, Shanks, or Mihawk. His strength is amplified by his survival instincts, cunning, and luck. If he were to regain his willpower and train seriously, he might become a much more formidable opponent, but as of now, his strength is moderate with a heavy reliance on his Devil Fruit powers and strategic mind
