Well, seem there is a topic about including Susanoo or some other things into the Uchiha KG, and someone said it would be unfair if the Hyuuga did get anything, here are some ideas for what the Hyuuga could obtain!
So there is a few Hyuuga jutsu that aren't in there, that could be included, but most are nothing special.
-Hakke Kūshō - Eight Trigrams Empty Palm: Just a powerful hit, maybe cause an opponent a debuff.
Jūho Sōshiken - Gentle Step Twin Lion Fists: Again, just a powerful double hit.
Shugohakke Rokujūyon Shō - Protection of the Eight Trigrams Sixty-Four Palms: This one could be alright, Hinata's little chakra done, basically lasts for x rounds and if enemies try and hit you, it arches back the damage at them plus more.
But the really good one, which could be used as a equaliser for Susanoo is, Hakke Hyaku Nijūhachi Shō - The Eight Trigrams One Hundred Twenty-Eight Palms.
Again, it is a powerful Jutsu, which would need training, as Neji had to train himself to use it. So you could have some sort of events where you learn to use it from Neji or other Hyuuga masters. You could have the Jutsu itself develop in stages, about three like Susanoo,
First Stage: A power jutsu, cost about 5 - 10 points, it does 128 small hits.
Second Stage: 5 - 10 Chakra Points, again does 128 small hits, and could stop Enemy Jutsus from happening after that point.
Third Stage: 10 - 15 Points, 128 hits, Stops Enemy Jutsus, and if any effects have started, ie debuff, they are removed.
Just an idea, also a possibility to train the Byakugan to last longer maybe? Just thoughts, what does everyone else think?
