Admiral Kizaru

As an admiral, Kizaru commands vast numbers of Marine subordinates. The most prevalent of the powers under his command is the Buster Call. He was able to defeat four of the Supernovas on Sabaody Archipelago with great ease. He also has extremely acute hearing, being able to hear activity underwater, before the Whitebeard War began. He possesses great physical endurance, as shown when he was kicked to the ground by Marco without even receiving a scratch. Kizaru is also capable of fighting Rayleigh and Whitebeard equally despite their Haki abilities. He also has great accuracy, as shown when he shot and destroyed the key to Ace's shackles whilst it was still in Luffy's hands. His extraordinary speed and precision makes him one of the most dangerous fighters within the World Government and Marines, fitting his title of Admiral.

Marco The Phoenix

As commander of the 1st division of the Whitebeard Pirates, Marco has authority over the lower-ranking subordinates. Following Whitebeard's death, Marco became the highest authority of the Whitebeard Pirates, and as such the crew was under his command as they retreated from Marineford. He was one of the few men unaffected by the powerful Haki released by the Yonkou Shanks. He is a very experienced veteran, as he was shown as a member of the Whitebeard Pirates from the times of Gol D. Roger.

Mihawk

True to his epithet, "Hawk Eyes," Dracule Mihawk has exceptional eyesight, able to easily track Luffy's Gear Second high-speed movements, and strike with extreme precision, releasing a long-range slash at him whilst there was a chaotic battlefront of New World veterans and Marine Officers between them. This ability may be enhanced by Haki, but this has yet to be confirmed.

Mihawk travels around in a coffin-shaped raft with two green-flamed candles, a single black sail, and a single seat. The fact that he can traverse the unforgiving oceans, as well as the Grand Line itself, in such a meager craft is yet another testament to his abilities.
