Hyuga Clan

Taking aside the Uchiha Clan, the Hyuga-clan is the strongest clan of the Leaf. They are known for their very powerful style of hand-to-hand combat and their bloodline limit of the Byakugan.The sharingan did evolve from the byakugan but they are two different powers. The byakugan does not possess the ability to mimic techniques. But in spite of that, it is still powerful. Like said before, the byakugan is the most powerful in terms of insight.
