Board Thread:Theories and Speculation/@comment-35622277-20170412000632

This is pure speculation, so don't hold anything to it.

In the first episode of Boruto: Naruto Next Generations, we are introduced to a mysterious and seemingly malicious entity that has the ability to control individuals harboring negative emotions. Coinciding with this, it is also revealed that Boruto possesses some sort of dojutsu before he came into contact with Momoshiki, capable of seeing this entity, and only activates in the presence of this said "entity", further cementing that the entity in question is or is something related to the being known as "Kawaki".

What if the name "Kawaki", is not referring to the host body, but the actual name of the entity whom is only possessing the host?

What if the "entity" was in reality another form of extraterrestrial life (stands to reason that other races may exist other than the Otsutsuki race) who had defeated an Otsutsuki in battle, who was also looking for immortality (like Momoshiki)?

Then "Kawaki" manages to find this "immortality", but in reality just only places himself into a non-corporeal state, resulting in him being eternally stuck between between the plane of life and death?

This can explain why "Kawaki" possesses a seemingly identical curse mark ability on his arm, which we can only assume was acquired the same way as Boruto did - defeating an Otsutsuki in combat.

As for Boruto's dojutsu, it may have something to do with Hinata's Hamura chakra mixing with Naruto's Six Paths chakra (probably not, but has to have something to do with Naruto though), as well as her possession of the Byakugan, creating some sort of dojutsu eye unique only to Boruto, capable of detecting any kind of chakra, resulting in his ability to see said entity.

It could also be that his dojutsu is the key to defeating Kawaki, as it stands to reason that once the host is killed, it can just jump to another, and that only Boruto's unique eye has the ability to destroy it's non-corporeal existence.

This could be the reason why Naruto (and possibly Sasuke) were incapable of defeating him, because the entity just kept on jumping to different people as he was constantly defeated, wearing the duo down. It also stands to reason that the curse mark grants the wielder immense power and chakra reserves, adding another reason why our dynamic duo was incapable of truly defeating him, as he was already insanely strong, and just kept returning almost immediately after it's hosts are killed.

This can also explain Momoshiki's words to Boruto after his defeat - that his eyes will take everything from him, because the entity knows that only Boruto can truly pose a threat to his existence, and targets his family (and as a result, Konoha) specifically.

The carnage that we see in the beginning of the series could also be a direct result of Naruto (/Sasuke) vs "Kawaki", and only moments after Naruto's supposed defeat. This makes sense, as Boruto seems to have just arrived, with none of their abilities activated and the particular way their exchange is worded, with both talking in present tense. The village also looks recently destroyed.

So if Naruto were to die, it would be near or at the end of the Boruto series, and not somewhere in between. His death would signify the end of the Shinobi era, with Boruto being symbolically the last Shinobi, so to speak. With Shinobi techniques and abilities falling to myth.

Also, everyone probably dies.

Not-So-Happily ever after, the end.
