With One Piece officially in its Final Saga, the last few arcs have had incredible moments that perfectly showcase how much greater the strength of the end-game characters is. From Luffy's insane feats in his Gear 5 state to Imu's appearance on the island of Elbaf, there have been many awesome displays of power that easily trump any that have come before in the series.

Chapter 1154 finally introduced the most hyped character in all of One Piece; the fabled Rocks D. Xebec. Not only was this man the most infamous pirate in history, but his incredible strength is the stuff of legend. Despite only being in the story for a very brief amount of time so far, Rocks has shown three feats that are far greater than anything seen before in the entire series, so let's take a look at what these are.

Rocks Managed To Break Into The Chamber Of Flowers In Marijoa

Imu's Secret Room

First Appearance	One Piece, Chapter 906, "The Holy Land Marijoa"
Story Arc	Reverie

Rocks somehow knew about the Chamber of Flowers and managed to break into it to confront Imu.

In one of the most insane twists in the entire One Piece story, Rocks somehow knew of the existence of Imu and their secret hideout within Pangea Castle, which is the Chamber of Flowers. The main reason why this is such an insane moment is because Imu's existence has always been kept hidden, since they are the sovereign who has ruled over the world in secret for 800 years. The fact that Rocks knew about them hints at much greater depth to him and his background as well.

Just wait, one day... I'll be back!

The true topic of their conversation remains a mystery at the current moment, but all we know is that Rocks promised that he would return to the Chamber of Flowers one day, which may give credence to one of the most popular Blackbeard theories out there, which is of Xebec somehow living within him. For now, though, everything remains speculative, but fans can see that Rocks' knowledge of Imu and their hiding place, and managing to break into it, solidifies him as the strongest figure of the old generation.

Rocks Was So Strong That He Killed A Navy Admiral By Himself

Something Even Yonko Haven't Done

First Appearance	One Piece, Chapter 303, "Rich Pirates"
Story Arc	Skypiea

Killing a Navy Admiral is something even modern Yonko haven't done.

A lot was revealed about the kind of fighter Rocks was in Chapter 1155. He was revealed to be a swordsman whose swordsmanship emphasized brute force instead of precise cuts and slashes, so much so that it apparently felt akin to cannon fire or a blow from a massive hammer. So impressive was his power that, in his time in Marijoa, he managed to kill a Navy Admiral all by himself, showing just how much of a powerhouse he truly was.

Rocks' swordsmanship was renowned for its brutal impact akin to a giant hammer or cannon fire. It was said to blow everything in the surrounding vicinity away.

Admirals have always been defined as the ultimate military force of the World Government and are generally considered to be among the strongest characters in One Piece. Although it's not a direct one-to-one, they serve as the World Government's answer to the Yonko since they're strong enough to compete with them. The greatest showing in a Yonko vs. Admiral clash was Shanks incapacitating Ryukugyu at the close of the Wano arc, but even then, no one has been able to outright kill an Admiral except for Rocks.

Rocks Destroyed The Gates Of Justice In The Best Ever Strength Feat

The Greatest Feat Of Strength Ever

First Appearance	One Piece, Chapter 376, "I Got It!!!"
Story Arc	Enies Lobby

Rocks, somehow, destroyed one of the gates of justice.

In perhaps the greatest feat of strength that has ever been shown in the entirety of One Piece, Rocks was stated to have destroyed the titanic Gates of Justice, which are the massive gates located behind three of the World Government's primary strongholds in Paradise. These gigantic gates are the size of entire islands and made completely out of metal, so to destroy them is something that no one could even conceive of, but somehow, Rocks was able to do this.

In the blink of an eye, Rocks' infamy boomed. The event sent a powerful shock throughout the seas.

It's unclear whether this was done through Rocks' own ability due to his mastery of Haki and his mysterious Devil Fruit ability or, if he did so along with his crew. Though the latter is the most likely, many fans are convinced he somehow managed to do this by himself, very brilliantly paralleling the Straw Hats' own stand against the World Government in the Enies Lobby arc. However, instead of merely burning the flag, the Rocks Pirates destroyed the Gates of Justice.
