Rocks D. Xebec was the captain of the Rocks Pirates. He was an ambitious individual who wished to topple Imu and become the ruler of the world. Rocks even met Imu but realized that the latter was stronger than him.

The old era of One Piece has many powerful haki users. Here are the most notable ones.

Rocks had access to all three types of Haki, and he was adept at using them. He was also an elite swordsman, whose attacks were potent enough to destroy the Gates of Justice. Furthermore, Rocks is the only character to have killed an Admiral. However, there are other One Piece characters who were stronger than Rocks D. Xebec.

This post contains spoilers for One Piece.

Gol D. Roger

The Only Person To Become Pirate King

Gol D Roger One Piece
  • Affiliation: Roger Pirates
  • Haki: Yes
  • Devil Fruit: No

Gol D. Roger was the King of the Pirates and the only person to have successfully claimed the One Piece. Roger lived around the same period as Rocks, and the two were fierce rivals. Oda hasn't shown a proper fight between the two, but the author has disclosed that Roger and Garp teamed up to beat Rocks.

Roger possessed all types of Haki, and he had perfect control over them. He fought the likes of Garp, Whitebeard, Shiki, and other powerful individuals, yet never suffered a loss. Initially, Roger was not stronger than Rocks, but he surpassed the latter after the God Valley Incident.

Whitebeard

Could Destroy The World If He Wanted To

  • Haki: Yes
  • Devil Fruit: Yes

Whitebeard used to sail with the Rocks Pirates before, ultimately, starting his own crew. He was a kind person who was not swayed by riches and fame. Whitebeard's only desire was to have a loving family.

Despite not being ambitious like Rocks and Roger, Whitebeard was just as strong, if not stronger than them. Whitebeard was the user of the Gura Gura no Mi, a Paramecia-type Devil Fruit that allowed him to create tremors. Depending on the need, Whitebeard could create a small shockwave or a full-blown tsunami that could wipe out an entire island. Whitebeard's Devil Fruit also made it impossible for attacks to reach him. While his Devil Fruit was overpowered, he did not rely on it entirely. In fact, Whitebeard was proficient at using all Haki types. After Rocks' death, Whitebeard's strength increased, and he became the "strongest man in the world."

Joyboy

Had Insane Haki And Nika's Power

  • Affiliation: Ancient Kingdom
  • Haki: Yes
  • Devil Fruits: Yes

Joyboy is a legendary figure from the Void Century and dubbed the "first pirate." He was against the World Government's tyranny, which is why the organization sought to exterminate him along with the Ancient Kingdom. Joyboy fought against the World Government but ended up losing.

Joyboy still remains a mystery to fans because Oda has hardly disclosed any information regarding him. However, the author did show Joyboy's incredible Haki. In the Egghead arc, Emet undid a knot that contained Joyboy's Haki. It was so strong that four of the Five Elders were sent back to Marijoa. Furthermore, it stressed out Imu, who immediately recognized that the Haki belonged to Joyboy. Based on the Haki feat alone, it's clear that Joyboy was a cut above Rocks D. Xebec.

Imu

The Strongest Fighter Within The World Government

  • Affiliation: World Government
  • Haki: Yes
  • Devil Fruits: Yes

Imu is the supreme leader of the World Government. Their existence is kept hidden from the rest of the world, as they control everything from the shadows. Only a select few people have ever seen Imu, and most of them have been killed.

Much about Imu's past remains unknown, but it's likely that they belong to the same time period as Joyboy. They have access to three types of Haki, and they can use them without any problems. Moreover, it is possible that Imu can use multiple Devil Fruits. All these qualities make Imu a much bigger threat than Rocks D. Xebec.

Monkey D. Garp

Known As The Hero Of The Marines

  • Affiliation: Marines
  • Haki: Yes
  • Devil Fruit: No

Monkey D. Garp is the most famous Marine in One Piece. The entire world knows about Garp's courageous acts, which is why he is considered the paragon of justice. Garp joined the Marines when he was still very young, but it didn't take him long to rise through the ranks and become a Vice Admiral. After attaining the rank, Garp refused all promotions because he didn't want to serve directly under the Celestial Dragons.

Garp does not have any Devil Fruits, so he had to rely on Haki and his physical strength. He underwent rigorous training to improve his Haki and strength. In his prime, Garp was the only Marine capable of matching Gol D. Roger. Considering Roger was superior to Rocks, Garp was also above the latter in terms of power.

Shanks

Was Called The Child Of Destiny

Shanks from One Piece
  • Affiliation: Red Hair Pirates
  • Haki: Yes
  • Devil Fruit: No

Shanks is the captain of the Red Hair Pirates and one of the Yonko. Shanks learned to use Haki when he was still very young. In fact, Shanks used Divine Departure at the age of 15. For the uninitiated, Divine Departure was the signature attack of Roger, and it required mastery over Armament and Conqueror's Haki.

Currently, Shanks is the strongest pirate in the world, and there is no one who can match him in a fight. Shanks hasn't had the chance to go all-out in a battle, but it's highly likely that he has surpassed Rocks D. Xebec. With time, it will become more apparent that Shanks is in a separate tier from most One Piece characters.
