My Life as a Teenage Robot is the future of Robotboy.
Dr. Wakeman was Professor Moshimo's student/pupil/fan. She was so inspired by Moshimo's robotics that she became a scientist herself. She somehow discovered about his secret experiment Robotboy. She taken some of his designs, blueprints, and schematics to built her own "Robotgirl". She had many failed prototypes until she finally builds XJ-9. Randy from "Human Fist on Ice" is secretly the actual Human Fist.
We last see him being chased by Kamikazi's jackal, and we don’t know why the Human Fist knew where Kamikazi and Constantine were. So, I theorise that Randy secretly is the Human Fist.Rupert Degas (the voice actor for Gus) was directed to try his hardest at an Eric Cartman impression for his role.
Seriously, that can't be a coincidence. It doesn't help that Gus and Cartman are in many ways essentially the same character.
