Benik was Ramón Salamander's assistant. He was eventually arrested for his crimes.
In 2018, Benik was confused by Donald Bruce's questions about Salamander's whereabouts. Bruce thought he had seen Salamander with Giles Kent but Benik assured him that Salamander had gone to the Central European Zone. Kent wanted Benik to contact Salamander for confirmation but Benik was under orders not to contact him.
Later, Benik confronted Kent in his caravan in the Australasian Zone and smashed up his equipment to threaten him. He led an attack on Kent's office to stop Fariah Neguib from exposing Salamander's plans, killing her. When Jamie McCrimmon and Victoria Waterfield were captured, he was looking forward to questioning them, but was ordered off by "Salamander" (in reality, the Second Doctor impersonating Salamander).
When Salamander was defeated, Benik was arrested by Bruce.
