Akainu is the strongest of the six characters who have held the Marine rank of Admiral—if you judge by the narrow edge he gained over Aokiji in their contest for Fleet Admiral. The rest of the all-time order is less certain: cross-era comparisons, age, and how much of each fight is shown make a definitive ranking impossible. This list is a reasoned comparison, not an official One Piece ranking.
Who counts as a Marine Admiral?
This ranking includes characters who held the formal rank of Admiral at some point in canon: Sakazuki (Akainu), Kuzan (Aokiji), Borsalino (Kizaru), Sengoku, Issho (Fujitora), and Aramaki (Ryokugyu). The roster reference describes three Admirals serving at a time and identifies Borsalino, Issho, and Aramaki as the current trio; Sengoku, Sakazuki, and Kuzan are former holders. One Piece Wiki’s Admiral entry is fan-maintained, so treat that roster summary as a reference rather than an official power ranking.
Sakazuki and Sengoku later held the Fleet Admiral office, while Kuzan resigned. Their change in office does not erase their earlier Admiral status. Garp is not included: despite his reputation and connection to Sengoku, his formal rank is Vice Admiral.
The strength ranking
The order weighs combat outcomes, the opposition faced, versatility, age and prime-era assumptions, and how much of a fight is actually depicted. It does not treat rank or command authority as proof of who would win. The middle and lower placements are especially debatable because the available evidence does not establish a complete head-to-head comparison.

1. Sakazuki (Akainu)
Sakazuki takes the top spot because he prevailed over Kuzan in the contest for Fleet Admiral. That outcome gives him the clearest direct edge over another Admiral on this list. It does not establish a huge power gap, nor does his later office alone prove he could defeat every other name.
2. Kuzan (Aokiji)
Kuzan’s candidacy for Fleet Admiral and his contest with Sakazuki place him close to the top. His loss is evidence of Sakazuki’s advantage in that contest, not proof that Kuzan is far weaker. The evidence used here does not support a more precise claim about the contest’s duration or conditions.
Rank #2

3. Borsalino (Kizaru)
Borsalino’s long-standing place among the Admirals makes a high ranking plausible. But the evidence available for this comparison does not establish a detailed feat-by-feat case for placing him above or below Sakazuki and Kuzan. Third is a judgment about the overall record, not a settled canon position.
4. Sengoku
Sengoku is the hardest character to compare with the others because his strongest reputation is tied to an earlier era. The fan-maintained Sengoku reference describes him as a Marine legend and recounts his fight against Shiki alongside Garp. It also reports that, at age 79, he helped defeat Jack alongside Fujitora and Tsuru. Those details support a high assessment, but they do not make elderly Sengoku equivalent to his prime or settle where prime Sengoku belongs relative to the current generation.
Rank #3

- What You Get: Anker USB-C Hub (7-in-1), welcome guide, 18-month warranty, and our friendly customer service.
A reader who prioritizes prime-era standing could reasonably put Sengoku higher. This list ranks him fourth because a cross-era reputation is harder to compare directly with the later Admirals’ records.
5. Issho (Fujitora)
Issho is a current Admiral, but the evidence here does not provide enough direct comparison to place him confidently against the veteran group. Fifth reflects the limits of the comparative record, not proof that his potential is definitively lower.
Rank #4

- Please Note: To reach 10Gbps speed, keep the cable under 3.3 ft. For USB A Male to USB C adapters, try flipping the USB C connector. USB C Male to USB A adapters support bidirectional 10Gbps transfer within 3.3 ft
6. Aramaki (Ryokugyu)
Aramaki is also a current Admiral, and the case for placing him sixth is close to the case for placing Issho fifth: the direct comparative evidence is limited. Their order is among the most debatable parts of this list, and the available evidence does not establish a decisive gap between them.

- Formal rank is not a universal combat tier. The Admiral title identifies an office with three holders at a time in the cited roster account; it does not automatically rank every Marine or establish a fixed win order.
- Authority and fighting ability are separate questions. Sengoku’s command role and Sakazuki’s later office matter to their careers, but neither office by itself proves the outcome of a hypothetical fight.
- Age and era change the comparison. Comparing prime Sengoku with current-era fighters is different from comparing him at 79. Any ranking should state which version it means.
- Shown fights and reported reputations have different weight. A result that is directly established offers a firmer comparison than a broad reputation or an incomplete account of a battle.
No official all-time strength order is established by the sources cited here. The clearest point of comparison is Sakazuki’s edge over Kuzan; the rest of the ranking is an interpretation of a thinner and less directly comparable record.
