Pinnepex

The  is a species of abnormal insects.

According to Dr. Helen Magnus, it was so ugly that it developed a method of concealing itself and was said to be extinct. Its main defense mechanism was to climb onto some other, larger creature and inject it with a special pheromone to cause aggression and the need to protect the Pinnepex. If for any reason the Pinnepex's current host becomes unable to protect it it'll immediately go in search of a new host. When the Pinnepex pheromones leave the hosts body they experience a memory loss of whatever they did as the Pinnepex host, this is so that the Pinnepex's former host doesn't know it exists and doesn't go looking for it later.

Shortly after the discovery of Hollow Earth, a Pinnepex found its way to the Old City Sanctuary on the body of a Mollox. In order to protect the Sanctuary team during the capture of the creature, Dr. Helen Magnus injected herself and her co-workers with a hastily engineered synthetic of the sex inhibiting pheromone of the Red Bollworm. They were eventually able to contain the Pinnepex after retrieving it from it's current host Dr. Lilian Lee.
