Cyber-Leader (Assimilation²)

They mind-controlled the researchers, making them unemotional and docile. The USS Enterprise was sent to investigate on stardate 3368.5. Captain James T. Kirk, Mister Spock, Doctor Leonard McCoy and Lieutenant Commander Montgomery Scott travelled to the planet's surface in the shuttlecraft Galileo, they were later interrupted by the Fourth Doctor, who was visiting the planet in his TARDIS. He helped them break the lock and together they infiltrated the facility. There, they discovered the archaeologists under the control of the Cybermen and tried to free them. A battle ensued and the Cybermen were destroyed with the Doctor's aid, while the researchers were liberated. (COMIC: Assimilation²)
