What is a wolf that leaves his pack and alone called?

There isn't a single, universally accepted term for a lone wolf that has left its pack. Here are some options:

* Lone wolf: This is the most common and straightforward term. It simply describes a wolf that is living and hunting alone.

* Outcast: This term implies that the wolf was expelled from its pack for some reason.

* Wanderer: This term suggests that the wolf is simply exploring and has no particular destination in mind.

* Solitary wolf: This is another common term that emphasizes the wolf's independence.

It's important to remember that not all wolves that live alone are necessarily "bad" or "outcasts." Some may simply be seeking their own territory or avoiding competition with other wolves.

Ultimately, the term you use depends on the context and the reason for the wolf's solitary existence.
