From Tardis Wiki, the free Doctor Who reference
Virus KX Variant 243 was a temporally active virus. When it infected someone, the victim's skin would turn transparent and the victim would be able to make short jumps throughout time and space.
Virus KX Variant 243 was utilised by a duo of Viyrans in London in 1918 and the far future. (AUDIO: The White Room, The Viyran Solution)
