Uberwolf

From Daemon Wiki

An uberwolf is a term coined by the daemians of The Daemon Forum referring to a surrogate form taken because the daemian thinks it's "cool". It may just be an ordinary animal that the daemian likes and will flaunt, but they often come with unusual, unrealistic traits, such as flashing silver eyes, golden fur, or extra appendages.

The term comes from the fact that a wolf daemon is usually the subject of this.
