Since the child Techno-Mage comics are usually much more lighthearted and comedic in nature, Fosschild was originally featured as a side character in the story, once Techno-Mage is an adult, to provide comedic relief. Techno-Mage meets Fosschild, a gifted homeless hacker, in Metacity and takes it in as her student. In some sense, she becomes Fosschild’s Puffy/Master.

The much more serious spin-off ‘Fosschild/Book of the Clown’ tells the story of Fosschild after Techno-Mage grows old. This series has not been explored much, apart for the few ‘mini’ panels, but it shows a much older Fosschild, OpenBlade and Penguin exploring a different part of the Analog Nowhere universe.
