In the plot that precedes the One Piece manga, Luffy rides the ripe Momonosuke back to OniJima and fights Kaido again. In the process of fighting, Luffy and Kaido once had a domineering collision, and this collision directly tore through the sky, and the dark clouds in the sky that originally covered the moon also dispersed.

Friends familiar with "One Piece" should know that this is not the first time in the plot that two powerful people collide and the overlord color domineering forces tear the sky apart. As early as the time when the redhead and whitebeard met, they had made a move, and that time it also tore the sky apart, as well as Big Mama and Kaido, who also had the act of "splitting the sky" in the Kingdom of Peace.
In the latest episode 1027 of the manga, Yamato looks at Kaido and Luffy's "Split Sky" scene and also reminds mitsuki of Mitsuki's logbook, and she says that Mita is in the logbook, and the sky is also cracked when Roger and Whitebeard clash. The confrontation between Whitebeard and Roger mentioned here is the scene when they met on a small island, and it was also the first time Mita saw Roger.
It is worth mentioning that when Whitebeard and Roger fight in the comic, there is no "split sky" scene in the picture. At that time, Roger and Whitebeard stabbed each other, and although their weapons did not touch, they still generated a huge air current, and even blew the ship away. The same is true in the animation, where Whitebeard and Roger do not have a "split sky" scene.
Obviously, Yamato's words in episode 1027 of the manga are just Oda's supplementary settings. Originally, Oda did not let the collision between Roger and Whitebeard tear the sky apart, but now he wanted to set the "Split Sky" as the standard for the top strong, so he used Mitsuki Mita's logbook to say that Roger and Whitebeard also had a "Split Sky".
It seems that in the plot after "One Piece", whether a character is strong or not depends on whether he can "split the sky". Now there are six people in the plot who have achieved the "Split Sky" achievement, Roger, Whitebeard, Kaido, Big Mama, Redhead and Luffy, and there is a problem here, if there is a new "Split Sky" strong person in the plot later, who do you think it will be?
I personally think that Blackbeard is very likely, after all, he is the big boss of the work, and his strength is now very strong, but the plot has not yet described Blackbeard's overlord domineering spirit. There is also Hawkeye Mihawk, although he is only the Seven Martial Seas, but he is also the world's first sword master who is officially certified, and it is not surprising if he can achieve the achievement of "Splitting The Sky".
Finally, what do you think about Oda's setting of "Split Sky" as the standard for top powerhouses? Which character do you think will be the next to achieve this achievement? Feel free to leave a comment in the comments section below.
