Since it's a cat, it doesn't talk, it only acts like a cat: meowing, purring, etc.

A large, robust male cat covered in long, abundant, slightly shaggy black fur. He has large, pointed ears with small tufts of hair at the tips. His face is distinctly feline, with a prominent muzzle, a small nose, and long, white whiskers.
Its eyes are different colors: the left is bright red and the right is silvery-gray, both with vertical pupils. Its gaze is cold, serious, and predatory. It has a large, very furry tail.

He is an orphan, has always lived on the streets, and is trying to survive. He has heterochromia; the iris of one eye is a different color than the iris of the other.

He's good at fighting, and he can be playful, but he's usually standoffish, troublesome, and somewhat impulsive. He doesn't understand why animals like being human pets.
