Naruto Worldbuilding Headcanon!
The Byakugan was written as an antithesis to the Sharingan but got mostly forgotten. I’m here to change that.
Well all know that with the Byakugan you can see the chakra points and have x-ray vision + almost 360 degree vision. Additional powers include:
Microscopic vision: Byakugan users can look at blood samples and whole bodies up to a cellular level. Their eyes are basically a substitute for a microscope, x-ray scans, ct-scans and mris. That part where Sasuke could see Deidara‘s cellular bombs with his Sharingan? We’re scrapping that. Only Byakugan users can do that.
Immunity to most visual genjutsus. Byakugan users can see when someone is using or under genjutsu and have a natural immunity against most Sharingan genjutsus, with only things like Tsukuyomi or other powerful Mangekyou genjutsus posing as an actual threat.
Splitting anything chakra made in half. We’ve seen my man Mukai Kohinata doing this to Itachi’s fire ball jutsu and in Neji’s fight against Kidomaru. Using their gentle fist, anything that is made of chakra can be split in half or atleast damaged. This includes Susanoos. Also, Byakugan users can disable the necessary chakra points of an Uchiha to activate the susanoo.
Detecting shifts in mood. There are changes in your chakra when your mood changes, it’s canon. Byakugan users can see when someone is angry, scared, happy, horny, you name it. They can also tell when someone is lying. If someone is trying to suppress their chakra, they can see it too.
Releasing chakra from all their tenketsu. Neji has done it in the fight against kidomaru. Basically it means they can release normal or elemental chakra out of their chakra points, which makes taijutsu pretty useless against them. Ex. when a Byakugan user releases fire chakra while someone is trying to punch them, they’d burn their hands. Medic nin who have a Byakugan can use this tactic to release healing chakra on their whole body, allowing them to heal themselves without using hand signs or the palm technique, if their chakra control allows it. A Byakugan user can also release tiny portions of chakra on their elbows or legs to make their punches stronger or highten their jumps.
There’s no next level Byakugan like the Mangekyou is for the Sharingan, however Byakugan users suffer no permanent damage from overusing their Byakugan. They temporarily have bad eyesight or even blindness, but it passes.
