Biography
Rubeish was transported to the middle ages and almost hypnotised by Linx the Sontaran that kidnapped him. He was saved by his low vision. He found a microscope lens and heated it up so he could see more clearly.

He snapped the other scientists out of there beam and teleported them back to the 20th century. He was the last man to get teleported back to the 20th century. (DW: The Time Warrior)
