This article contains spoilers from the Boruto series.
Boruto: Two Blue Vortex has been incredibly exciting from the very beginning, and it continues to get better with each passing chapter. While the story wrapped up some massive events recently, like Sarada's awakening of the Mangekyo Sharingan, Boruto: Two Blue Vortex has now started an arc that is even more intense. In fact, it wouldn't be a stretch to say that just the beginning of this arc is far more intense than anything the previous arc did, and everything that has been accomplished by Kashin Koji's Prescience Vision.
Thanks to his visions, the new major threat to the world has been officially confirmedand much to the surprise of fans, it is not Jura or Hidari, but another Shinju who is currently central to the plot, and that is Mamushi. Mamushi is strong on his own, and his abilities are great enough to compete with even the strongest characters, such as Boruto Uzumaki. However, he will grow even stronger. Kashin Koji confirms Mamushi's impending evolution which will make him the strongest in the worldsurpassing even the likes of Naruto Uzumaki. Even with Baryon Mode, Naruto Uzumaki would pale in comparison to what came next in Boruto.
Boruto's new Shinju villain will be the strongest character in the series
-
Mamushi will consume Eida
-
Eida will grant Mamushi Omnipotence
Right now, all Shinju are incredibly powerful beings with enormous strength up their sleeves. The fans already know this very well and it is also clear Jura is the strongest of them all. But Jura being strongest is only based on the basic future that Kashin Koji saw. In fact, every other action that takes place in the new future changes the future that Koji saw, so Mamushi's evolution, which may happen in the new futurecould potentially make him the strongest Shinju.
Mamushi has a dangerous ability. He can reproduce as much as he wants, and each copy is the real deal, not like Shadow Clones. – Kashin Koji
Kashin Koji's future confirms that Mamushi is eating Eida
As some fans may recall, Mamushi's goal is to get to Eida and consume her. This goal will not be easy to achieve, but Kashin Koji has already seen the future and in it Eida falls and is devoured by Mamushi. Even Damon, who is known for being strong, couldn't stop this future from taking place. Of course, Boruto Uzumaki and everyone else is working to stop Himawari's death and prevent Eida from being consumed. That said, it is possible that only one will survive. If Eida falls, Mamushi will evolve into a new powerful Shinju whose powers will be off the charts. This would make Mamushi the first Shinju to fulfill his instinct and evolve, and fans can't wait for it.
Mamushi's evolution will surpass even Baryon Mode Naruto
Mamushi is seen as the weakest of the Shinju right now, and that's a fact. Hidari and Jura are much more powerful. But the fact is that Mamushi could potentially evolve. If he does, he will gain Eida's powers. It must be remembered that Senrigan probably won't pass over Mamushi since Sasuke's Sharingan didn't transfer to Hidari. They all kept their Rinnegan. But all other abilities did. This means the most dangerous Shinjutsu of all, that is, Omnipotence, will transfer to Mamushi as well.
Come on, Otsutsuki! I will show you what the true determination of a shinobi is like. —Naruto Uzumaki
If Mamushi gains access to Omnipotence, and most importantly, learns to control it, something even Eida cannot do, then the world is doomed. Not even a single character can save the world in that case, then Omnipotence is a Shinjutsu among Shinjutsuas confirmed by Momoshiki. This technology can't be beat because it can turn anything into reality. Even Baryon Mode Naruto wouldn't be able to beat Mamushi with full control of Omnipotence, and it's terrifying.
Naruto asserted his dominance in the ninja world for years. right now, his Baryon Mode is far superior to Jura's. But against someone with Omnipotence, Naruto can't do anything, which means he'll be deposed soon enough in the Boruto series. It's only a matter of time before Mamushi comes to Eida. Whether or not Eida will be consumed remains to be seen, but the fate of the world rests on her survival. Hopefully the next few chapters will come off Boruto comics will clear things up regarding Mamushi and his evolution.
