Kurtz
Feldwebel Kurz was a german officer at Colditz Castle, and was in direct contact with the majority of the prisoners there. He was rather vicious in nature, delighting in causing harm to the prisoners, especially ones who had tried to escape. When Ace and The Doctor arrived by accident there, he took a particular interest in her and the contraptions. First of all he dismantled a cd walkman, then tried to advance on Ace, even at one point trying to rape her.
Her was used a lapdog for Dr. Elizabeth Klein, when she quested after the time travellers, mostly threatening to shoot Ace, if the doctor didn't comply with her demands. When the Doctor eventually opened his TARDIS to her, The Doctor de-materialised with the doors open, and Kurz was inbetween the outside world and the interior dimensions of the TARDIS, ripping him apart. His death appalled Ace so much that she started wanting to be referred by her birth name, Dorothy McShaine. (BFA:Colditz
