Solow

Solow was a doctor working in Sea Base 4 in 2084.

Solow, along with Nilson, was a convert to the ideology of the East Bloc, the power bloc opposed to the base. After the death of Solow's husband and parents, Nilson convinced her that the philosophy of the East Bloc was the answer to all of life's problems, but for the East Bloc to wipe out all suffering and injustice on Earth, sacrifices would have to be made. (PROSE: Warriors of the Deep)

Solow had mentally programmed another crew member, Maddox, in order to destroy the base computers.

When the Sea Devils attacked the base, Nilson sent Solow to an escape pod. On her way to the pod, she ran into the Myrka, and was fatally electrocuted when she tried to use martial arts on it. (TV: Warriors of the Deep)
