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". Kath lured him to an airlock and ejected both of them into space in order to save the others. They flew into space in each other's arms. (DW: 42)
