Maddox (Warriors of the Deep)
Maddox was a human who was training at Sea Base 4 when he fainted Dr Solow said he was unfit for duty and she took him to the medical bay. There she reporgrammed his brain and made him sabotage the computers. In doing so another person working at the Sea Base known as Karina found out what he was doing. He was forced to kill her under the orders of Nilson the man working with Dr Solow. He made a copy of Sea Bases 4 and put it on a disk. There Dr Solow ran off with it only to be killed as the Sea Devils and Silurians where attacking the base at the time. He was eventually killed by Nilson from giving away information about Sea Base 4 but was killed when Nilson over loaded his power systems that let his brain function. (DW: Warriors of the Deep)
