Kurama (Earth-2356)

"I suppose I can't kill you, can I? After all, you die, I die. Your courage is impressive, youngling... Very well, as a reward for making it this far, I will loan you my Force!"

- Kurama to Anakin Skywalker

Kurama, more commonly known as the Nine-Tails, is one of the nine Bijuu. Millenia of being regarded as a mindless monster and sought after as a tool for war caused Kurama to hate the beings of the galaxy. After being sealed into Anakin Skywalker and later his son, Luke Skywalker, Kurama attempted to maintain its negative opinions about the galaxy, but eventually with Luke's insistence on treating it with respect, the creature overturneds its hatred and willingly strived to use its power for the galaxy's salvation.
