Kurama (Sig)

Kurama (九喇嘛, Kurama), more commonly known as the Nine-Tails (九尾, Kyūbi), is one of the nine. Centuries of being regarded as a mindless monster and sought after as a tool for war caused Kurama to hate humans. After being sealed into, Kurama attempts to maintain its negative opinions about the world, but with Naruto's insistence on treating it with respect, the fox overturns its hatred and willingly strives to use its power for the world's salvation. After Naruto's death, Kurama returned back to his former self drowned in everlasting hatred for the humans. After being caught by Mokushi he was sealed into Ninigi Uchiha and split into two separate entities somehow returning him to a child-like state.
