Someone must have created and programmed him originally. But considering everything, it need not have been the doctor. Maybe it was a version of him in some other world.

[Whoever he is, their foe is totally unfamiliar to the Sonic team and has proven capable of interdimensional travel already. The realm of possibilities is broad indeed.

What's certain is that while Viktor may have always related to Dr. Robotnik, Turo has always related more to his mechanical creations, especially the copies he's so fond of making. What separates him from something like Mecha Sonic, or a Shadow android? Luck? What separates him now from their final foe?]

He may be limited in his ability to see reason.
