Tenza had advanced, though subconscious, psychic powers, allowing them to live among other species. They used a psychic field and a perception filter to remove inconsistencies in their histories. One Tenza was capable of capturing people who frightened him, shrinking them to fit inside a doll house and eventually turning them into living dolls. He could also contact the Eleventh Doctor's psychic paper when he was millions of light years away, albeit unconsciously and in a fit of fear. (TV: Night Terrors)
