What is a rogue?

Answer 1

A solitary animal outside a herd (notably an elephant) is called a rogue.

A rogue as a person is also one who is separate or outside the rules of society, as a scoundrel or rascal. It is often used in a romantic context ("a dashing rogue") to mean a man found attractive because of his adventurous or daring nature, such as an outlaw.

The word rogue can also apply to a disconnected event, such as a "rogue storm", that happens outside the usual location or conditions.
