luo xiaohei
The titular character from The Legend of Luo Xiao Hei.

His animal form takes on the appearance of a black cat with black eyes.
The miniature creatures sometimes seen around him - resembling disembodied cat heads - are called Heixiu. They are made by Xiaohei himself, as he possesses the ability to break off pieces of his own tail into autonomous creatures.
