He arrives travels to the 21st century, arriving at the London home of Professor Gryffen, a renowned scientist working on the Alien Space-Time-Manipulator (STM), which can open a portal to anywhere in space and time. When alien warriors attack Gryffen and two teenagers - Starkey, a homeless rebel, and Jorjie, an intelligent young girl, K-9 self-detonates to save them, but is soon regenerated thanks to a device implanted in his mainframe.
