Hal Korwin

Korwin McDonnell was the husband of Kath McDonnell, and was part of the crew of the SS Pentallian. He was possessed by the star Torajii, and went on a killing spree of the crew. He wore a Welding helmet to keep his eyes from shining all the time. He also transferred his powers to Dev Ashton.

Even when possessed, Korwin recognized his wife, but claiming "its all her fault". When Kath was trapped in an airlock, Korwin went in to kill her, but she opened the airlock and they flew into space in each others arms. (DW: 42)
