Taphony

Taphony was a Time Blank created by the Department through their various attempts at time travel. They molded the continuum into her image but when she turned out to be too powerful they imprisoned her in a virtual reality detention facility. She was later released by Professor Alistair Gryffen, who had a hand in her creation, and escaped to Gryffen Manor. She befriended Starkey, Darius Pike and Jorjie Turner, but required Jorjie's life force to sustain her existence in normal time (she also rapidly aged Gryffen for his role in her imprisonment). Although she wanted to stay on Earth, she was eventually convinced by her friends that she needed to leave, and departed through the Space-Time Manipulator into another dimension. This reversed time to the point where Gryffen first released her, although K9 (being a time traveler himself) still retained his memories of her. (K9TV: Taphony and the Time Loop)
