Summary
When it comes to Haki, fans have seen quite a lot of powerful users after the timeskip. However, among the many users of this powerful ability, only a handful can be considered to be strong enough to split the skies. In fact, being able to split the sky with Haki is proof of someone being a top-tier Haki user, and, more importantly, someone on the same strength tier as the Yonko.
Oda has only had a select few individuals split the skies inOne Pieceso far, with a handful of others having the capabilities to do so.
8Big Mom
Big Mom is clearly one of the strongest Haki users inOne Piece, and fans have canonically seen her split the skies in her clash against Kaido in the Wano Country arc.
On Onigashima, Big Mom and Kaido engaged in a long duel that lasted for over a day and this resulted in the sky over Onigashima splitting apart, signifying the advanced Haki mastery that Big Mom has.
7Kaido
Just like Big Mom,Kaido also has access to incredibly powerful Haki. In fact, up until recently, Kaido was easily one of the mightiest Haki users in One Piece. Kaido has split the skies on many occasions. During his battle against Big Mom on Onigashima, he managed to split the skies with her.
Later on, during Kaido’s battle with Luffy, he split the sky once again, which just goes to show that his Haki is absolutely tremendous.
6Luffy
Luffy has consistently grown his Hakiin the post timeskip ofOne Pieceand in the Wano Country arc, his Haki finally reached the point where he could split the sky with someone.
He did it for the first time during his clash with Kaido on Onigashima, and this was an indication from Oda that Luffy had now officially reached Yonko tier status as a very powerful pirate.
5Garp
Garp is an individual who fans have not seen split the sky inOne Pieceyet, but he certainly has Haki of the highest grade.Garp is a user of advanced Conqueror’s Haki, and it is unfortunate that fans have not seen him fight against someone with advanced Conqueror’s Haki, so that they could go on to split the skies.
Given that he fought against the likes of Roger in the past, these two certainly would have gone on to split the skies at some point.
4Whitebeard
Whitebeard is an individual with tremendous Hakithat fans have seen splitting the skies on multiple occasions. During his battle against Shanks on the Moby Dick, these two managed to split the skies efficiently and it was actually the very first display of the heavens splitting apart inOne Piece.
During his fight against Roger in the flashback of Wano, fans saw him splitting the skies once again, although this time, Oda did not focus on the heaven-splitting effect as much and simply showed the clouds being pushed away.
3Roger
Roger is an incredibly powerful individual and certainly one of the mightiest Haki users in all ofOne Piece. Fans know him to have wielded tremendous Haki, and he’s confirmed to be the strongest Haki user of his era.
Roger clearly had Haki strong enough to split the skies, and during his clash against Whitebeard, it was clear for the fans to see that he managed to destroy everything in his vicinity and even push the clouds away.
2Shanks
Undoubtedly, the strongest Haki user of the current era ofOne Pieceisnone other than Shanks. Fans know him to possess Tremendous Haki, which he can utilize in many ways. Shanks possesses Haki so incredible that he can easily split the skies.
Fans have seen him split the sky with Whitebeard before, and, in fact, there remains a possibility of Shanks being strong enough to split the skies all by himself, given that his Haki has directly drawn comparison to Joy Boy.
1Joy Boy
Undoubtedly, the mightiest display of Haki in the entirety ofOne Pieceso far comes from Joy Boy. In the Egghead Arc,Joy Boy displayed a portion of his powers through Emet, after having stored it inside his body.
When Emet unleashed this Haki, Joyboy managed to split the skies all by himself, knock out all Vice Admirals of the Marines, nullify the demonic powers of the Five Elders, and send four of them back to Marijoa, as well as send shivers down Imu’s spine, all the while causing them tremendous pain. So far, this is the greatest display of Haki in One Piece and undoubtedly, Joy Boy possesses tremendous skill in this department.
