De Haan

De Haan was an officer of the Morestran ship which answered the distress call sent from Zeta Minor. He was a member of Vishinsky's landing party, which discovered Sorenson and captured the Fourth Doctor. He and Morelli carried out Salamar's orders to return Sorenson's anti-matter samples to the planet. He later discovered Morelli's body, and was killed by the transformed Sorenson. (DW: Planet of Evil)
