|Behind the Scenes|
Dr. Fen is a robotics scientist who later turn out to be a fraud who stole from his former assistant Vivian Porter.
Dr. Fen at first appeared to be an amiable and polite man who often got the into trouble with the machines he worked on. But when his deception was revealed, Fen showed himself to be a conniving and ruthless thief as he attempted to destroy Dr. Vivian Porter's creations to secure his freedom.
Dr Fen was, or rather appeared to be, a robotics expert. However he was not a very good one which was apparently obvious since Dr Possible questioned how such a clueless man could have been an authority on robots to begin with. But despite his apparent lack of intelligence, Fen was at least cunning enough to trick Kim and Ron into stealing for him and fool the Middleton Space Center into believing that he was robotics expert.
Vivian Porter hated Dr. Fen for stealing credit for her work. Something which he refused to give her as it would deem him as a terrible scientist.
