Rutans share the Sontarans' ruthlessness, caring little or nothing for other species. They can adopt different physical shapes and are able to kill with a single touch of their tendrils. But they are vulnerable to fire and can be destroyed using fairly crude weaponry. As a race they will stop at nothing - even the obliteration of Earth - in their quest to defeat the Sontarans.
