Derek Moberley

Derek Moberley was a zoologist working at a base in Antarctica. He and his colleague Charles Winlett discovered a Krynoid pod in the permafrost while digging for samples. After Winlett became infected by the pod, Moberley reluctantly agreed to perform surgery on him to slow down the infection, but was strangled and killed by the transformed Winlett.
