WMG / Grand Unifying Guesses Sonic The Hedgehog

Doctor Robotnik has built every single machine ever
Robotnik, who is also a Time Lord, is clearly able to construct any machine regardless of size in a very short period of time. Just look at the Death Egg in Sonic the Hedgehog II or the mechanized cities shown in all of the games. It stands to reason that Robotnik, who has never been shown as a patient, rational person, must do SOMETHING to avert his boredom. That and the fact that he never seems to build enough to ever defeat Sonic, must obviously mean that he takes on side jobs.

In Sonic Adventure, given his ability to build a massive, several mile fortress during the ten minutes or so that it takes for Sonic to escape the Egg Carrier after he leaves, assuming the fortress is about 100,000 tons, it stands to reason that he is able to build at a rate of approximately 2.777 tons of machinery per second. With this information, the only logical conclusion that one can come up with is that Dr. Robotnik has singlehandedly built every last machine in existence in any work of fiction. Everything from the Death Star to the time traveling DeLorean to KITT is his handiwork. If anyone else claims credit for his work, they are just simply dirty liars. Anyone shown to be physically working on anything is either pretending or otherwise got a DIY kit from Robotnik.
