As the name suggests they have red hair, but they're not normal. They're pale as all hell and have at least one freckle. Aliens, they are also aliens. So put on your tinfoil hats when in the presence of one.
A woman that's extremely hot and causes heads to turns. You're lucky if you find a natural one! Those are rare nowadays. If you got one, never let her go because a redhead is by far the most unique woman you'll ever meet!
