This is Shin, a character who is very dear to me. I've had him for many years and he is a character I find myself relating to a lot emotionally.

He is a type of Kyuubi (or mythical Nine-tailed-fox) that has the power to shape shift into many different forms temporarily by sampling the blood of whatever he wants to change into. The ability to take another form can be permanent if he kills a victim, essentially now able to take their place. He can also breathe a fire that appears "black" and lift very heavy objects to an extent with both his arms and his tails.

His most favored forms are his human form and his bipedal demon-like Kyuubi form. He can also change into a small dark grey fox to appear less threatening as well as transform into two different dragon forms when he needs more power. The pure black dragon form is his viral form which he takes in the astral plain.

He is a calculative guy and keeps a somewhat indifferent attitude most of the time. His more ferocious disposition surfaces when he is angered or protecting something. When doing so, he becomes extremely aggressive and reckless, throwing his strength around until his anger is extinguished or the threat is destroyed.
