King Harald hailed from Elbaf, the land of the Giants. In his younger days, he was a menace who caused problems for everyone, but things changed after meeting Ida. Harald became more responsible and mature. He realized his duty to the people of Elbaf, which is why he worked hard to make the World Government accept it as an affiliate country.

It Is Time To Admit That Shanks Is Stronger Than Gol D. Roger In One Piece

Roger is strong, but Shanks has already surpassed him in One Piece.

By 

Aside from being a top-notch diplomat, Harald was also an incredible fighter who could stand his ground against the most dangerous opponents. With his insane physical strength, Harald could even go toe-to-toe with someone like Davy D. Xebec. However, Harald isn't completely unbeatable. In fact, there are several One Piece characters who are stronger than Harald.

This post contains spoilers for One Piece.

Gol D. Roger

Affiliation: Roger Pirates

  • Haki: Yes
  • Devil Fruit: No

Gol D. Roger was the captain of the Roger Pirates and the only person to obtain the title of King of Pirates. He was an ambitious man who never let the constraints of the world hold him down. Roger's ambition meant that he often had to go up against the strongest characters in One Piece, which is why he worked on his strength.

Roger didn't have a Devil Fruit, so he had to rely on Haki to get the job done. After repeatedly fighting some of the most well-known characters of the old era, Roger's Haki became so potent that he could one-shot someone like Kozuki Oden without any problems. While Harald was definitely a powerful person, he couldn't beat prime Roger in combat.

Whitebeard

Affiliation: Whitebeard Pirates

  • Haki: Yes
  • Devil Fruit: Yes

Whitebeard was known as the strongest man in the world because of his absurd physical strength and Devil Fruit. He possessed the Gura Gura no Mi, which enabled him to create tremors at will. Potentially, Whitebeard could wipe out an entire island within seconds with his ability. At the same time, Whitebeard had to be careful, as his crewmates could get caught up in the attacks.

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

Despite the insane Devil Fruit, Whitebeard wasn't entirely dependent on it in fights. He had access to Haki, and he often imbued his Saijo O-Wazamono grade weapon with it to fight his enemies. Whitebeard's Haki might not have been as potent as Roger's, but his Devil Fruit made up for it. By combining the two abilities, Whitebeard would have no problem beating Harald.

Monkey D. Garp

Affiliation: Marines, World Government

Garp vs. Kuzan 3-1
  • Haki: Yes
  • Devil Fruit: No

Monkey D. Garp is one of the few Marines in One Piece who is capable of holding their own against the strongest pirates. Unlike most high-ranking Marines, Garp does not have a Devil Fruit. To make up for its absence, Garp trained his physical body to the point where his punches could damage seastone.

Garp also has access to all three types of Haki, making him part of an exclusive list. His rigorous training and continuous fighting improved his Haki and allowed him to stand on equal footing with the Pirate King himself.

Imu

Affiliation: World Government

  • Haki: Yes
  • Devil Fruit: Yes

Imu occupies the Empty Throne in Marijoa, making them the ruler of the world. They have been alive for centuries and made every single decision for the World Government. Imu is ruthless and calculating, always doing whatever benefits them. Despite their cruelty, no one has managed to end Imu's reign, and that's mainly because of the sovereign's incredible abilities.

One Piece: 8 Mind-Blowing Revelations About Shanks

Shanks' past has been a source of speculation among One Piece fans for years, but these revelations were a shock even to the most devout theorists.

Imu is immortal and has the power to regenerate from any attacks. They also have access to a special ability called Domi Reversi, with which they can turn anyone into a demon and control their actions. Imu can also use multiple Devil Fruits and Haki. Considering their strength, it's not a surprise that Oda has picked Imu to be the final villain in One Piece.

Five Elders

Shanks

Affiliation: Red Hair Pirates

  • Haki: Yes
  • Devil Fruit: No

Shanks is the leader of the Red Hair Pirates, and arguably the strongest active character in the series. Shanks is a prodigy who learned Roger's Divine Departure at the age of 15. What makes this an incredible feat is that the attack utilizes Advanced Conqueror's and Armament Haki. Being able to use it at such a young age means that Shanks had mastered the use of both.

Since then, Shanks' strength has only improved, and he has become feared by pirates and Marines alike. In fact, he was able to scare away Admiral Ryokugyu with his Conqueror's Haki.

Joyboy

Affiliation: Ancient Kingdom

  • Haki: Yes
  • Devil Fruit: Yes

Joyboy is a legendary figure from the Void Century who spearheaded the fight against the World Government. His actions earned him the honor of being called the "first pirate."

A lot about Joyboy remains a mystery, but Oda has shared a few details about him. For starters, it has been confirmed that Joyboy had eaten the Hito Hito no Mi, Model: Nika, the same Devil Fruit as Luffy. He also managed to awaken the Devil Fruit, as Emet confirmed that it had heard the Drums of Liberation in the past. Joyboy also had insanely powerful Haki. When Emet undid the knot containing Joyboy's Haki, it knocked out low-ranking Marines and the Vice Admirals. Furthermore, it forced the Five Elders to revert to their human forms and sent three of them back to Marijoa.
