Lynx was a cat generated by the Doctor's TARDIS. He was a projection that followed the Seventh Doctor and Ace through space and time on three accounts. Firstly he followed them to a Wasteland ruled by a being known as the Process, which they had been brought to from 1991 London. (NA: Cat's Cradle: Time's Crucible)
