Cyberman (The Daft Dimension 482)

In the Daft Dimension, a Cyberman once snuck onboard the Doctor's TARDIS alongside a Silent, Dalek and Zarbi. However, the Doctor forced them to reveal themselves by scraping his nails on his blackboard, producing a sound which all four monsters found unbearable. Indeed, the Cyberman, in contrast with its supposed lack of emotions, declared that it "hated" the sound. (COMIC: The Daft Dimension 482)
