One Piece fan theory: Rocks D. Xebec’s Devil Fruit. (Spoiler Alert)

In Chapter 1007, it was revealed during the battle between Who’s-Who and Jimbei that Who’s-Who was a former CP9 member who fell from grace because he failed in his mission to guard the Gomu Gomu no Mi (Rubber Rubber Fruit) for the World Government. He was attacked by Shanks, who manages to steal the devil fruit from Who’s-Who and eventually the fruit was eaten by Monkey D. Luffy in the beginning of the series.

Gomu Gomu no Mi

This begs the question why was this particular devil fruit so important to the World Government. Throughout the series it was revealed that many devil fruits have been catalogued with their names and powers for reference. Some examples of devil fruits that were known before consumed by the current users are the Yami Yami no Mi (Darkness Darkness Fruit), Ope Ope no Mi (Operation Operation Fruit) and the Suke Suke no Mi (Clear Clear Fruit). Why then was the World Government interested in a low level Paramecia fruit?

The possible theory is that the Government wanted the Gomu Gomu no Mi to counter a specific devil fruit, the Goro Goro no Mi (Rumble Rumble Fruit) which gives the user the Logia ability of controlling and becoming lightning. During the Skypiea Arc we saw how powerful Enel was as the current Goro Goro no Mi user, he was virtually unstoppable and had declared himself a God on Skypiea until he fought Luffy who was unaffected by this power as electricity has no affect on rubber which became the main reason Luffy managed to beat him in the fight. Even under the Logia hierarchy theory, electricity would be one of the most powerful Logia types as it is virtually stronger than most elements with the strength and speed to easily overpower any of the three Admirals powers.

How does all of this related to Rocks D. Xebec? In Chapter 957 Sengoku revealed that the God Valley incident involved the Rocks Pirate crew attempting to wage war against the Celestial Dragons and it took Monkey D. Garp teaming up with Gol D. Roger to take down Rocks. The incident was covered up by the World Government and Rocks remains a dark chapter in the history of the Marines and a reason why Kaido and Big Mom’s team up in Wano to be considered dangerous by Sengoku.

Rocks Pirate vs Roger and Garp

Given how powerful Rocks is, as he was able to be control his crew who not only consisted of three Emperors in their youths (Big Mom, Whitebeard and Kaido) but also various other pirates who eventually became a big name in the New World, it would make sense that Rocks was the previous user of the Goro Goro no Mi which is why it took the Garp and Roger to be able to defeat him. Robin also stated in Chapter 274 that among the Logia fruits, the Goro Goro no Mi was said to be unrivaled in power which mostly likely was due to it being wielded by Rocks. However, the World Government could no longer rely on Garp to take down another user of the Goro Goro no Mi should they appear in the future and obtaining a fruit to counter that particular ability was needed.

It also makes sense that there was a previous Goro Goro no Mi user before Enel as he had eaten the fruit only in Skypiea 8 years prior to his appearance. There had to have been a powerful user before Enel that created enough fear for the World Government to specifically search for the Gomu Gomu no Mi and assigning a CP9 member to protect it. This why the most possible conclusion is that Rocks D. Xebec devil fruit was the Goro Goro no Mi.
