Seeing that Luffy and his alliance have succeeded in defeating Yonkou Kaido and Yonkou Big Mom, a new pirate era seems to have successfully started with Luffy, Law, and Kid as the spearheads of a new era on the pirate side.

Then if a new era on the pirate side has been brought up by Oda-sensei, when will it be the turn of the Marines to show new people from their generation?

The problem is that without us realizing it since the Gol D Roger era or even further from the JOYBOY era itself, there should always be two people from every generation who hold both opposing sides.

Like the combination of Garp and Sengoku, for example, who triumphed in the era of the pirate king Gol D Roger, or there is also Im the same who most likely became an enemy of Joyboy in the past.

Therefore seeing Luffy et al shown as the beginning of a new era, it seems that it will not be long before the generation of the Marines will be shown, and most likely all of this will focus on a super secret organization owned by the Marines, namely S.W.O.R.D.

SWORD, an organization consisting of people from the Navy, is either still active or has left and is known as a new organization and only known by a few people.

Then if we relate it to the emergence of the CROSS GUILD organization led by the new Yonkou Buggy the clown. So it's possible that the awakening of a new era from the Navy side will focus on this incident, bearing in mind the appearance of the CROSS GUILD should be a very real danger signal, because currently Marine soldiers are being hunted by anyone who wants to make money.

But how do you ensure that the emergence of CROSS GUILD will be a turning point for a new era for the Navy? To answer this, we can see how Luffy and his alliance opened an era by defeating two Yonko at once.

So if defeating a yonko is seen as a way to start a new era, the existence of Buggy who was appointed as one of the yonko to replace the positions of Kaido and Big Mom, seems like it was deliberately made to be a turning point for the Marines to defeat a Yonko.

It will be interesting to wait to see how Oda-sensei will bring about a new era on the Marine side. Because Coby, who became one of the most potential people in his era, was having a hard time because he had to deal with super strong pirates.

Meanwhile, on the other hand, changes in the Marine side have begun to be seen, because two of the three people in the current admiral position are not from the generation when Luffy just started his journey to get a treasure called One Piece.
