Appearance
(Taken from the villains fanon wiki, page created by same person)

He has a red Crystal on his shirt, purple pants, a cape with purple diamonds on it, a orange nose, brown eyes, black and white fur, with red and orange shoes. His ears are pink, and his tail is white although his whole body is brown, and he is an Husky as in his last name.

Personality
(Taken from the villains fanon wiki, page created by same person)

His personality when first meeting someone, is nice, selfless and willing to help anybody and greet people. But that later changes when Kush is either mad or angry, even at them.

Of that personality, he seems to be an obnoxious, rude, selfish person who focuses too much on his own plans and seems to be stronger then he looks at first. He also seems to get angry easily, which shows his obnoxious side, in his second appearance.
