The Byakugan needs some love. Hyuuga means Sun/Day/Towards the sun.
The sharingan is all about darkness, the moon, losing light if you use your MS to much.
The Byakugan is about light, the sun.
I will suggest an upgrade to the Byakugan in this thread, including a name.
The Sharingan has the Mangekyou Sharingan.
The Byakugan will have the:
Kagayaki means SHINE. I will use ''KB'' (Kagayaki Byakugan) in the rest of the thread.
The powers that the KB gives, should be related to the sun.
The appearance of the KB, would be a Byakugan, that SHINES (like the sun).
Being able to utilise the power of the sun.
Blinding their opponents, by releasing a blinding shining light from the KB.
Full light, 360 degree vision. No blind spot.
Absorbing sunlight, the energy of the sun through looking at the sun (wich isnt hard with 360 vision :p).
They can use this energy for a quality and quantity increase in chakra.
Increasing their endurance and speed greatly during daytime.
They can release a greater amount of chakra from their finger tips and the rest of their body
with the energy of the sun, thus allowing a greater range for their techniques.
Immune to Genjutsu (not only able to see who is under it).
