Sabo is an extremely strong character in the One Piece universe, known as the "Flame Emperor" and Chief of Staff of the Revolutionary Army. His strength is considered to be near the level of a Marine Admiral, such as Fujitora, as they have fought without going all out against each other. Sabo has defeated Marine Vice-Admiral Bastille and Blackbeard's commander Jesus Burgess with ease, demonstrating his power above most Yonko Commanders and Vice-Admirals. His base physical strength is impressive on its own and is further enhanced by his mastery of Armament Haki and the powers of the Mera Mera no Mi (Flame-Flame Fruit), which he inherited from Ace. He is regarded as one of the top fighters within the series, comfortably ranking in the top 15 characters and potentially higher. Despite his power, he might struggle against the top-tier Admiral level fighters like Akainu or Ryokugyu due to their overwhelming strength and Devil Fruit abilities.
