Professor Neinstein was a famous Mobian physicist. Shortly before his death, Neinstein was rumoured to have created an Energy Absorption/Transmission Device that could swap the powers of one person with another's. Doctor Robotnik learned of this invention and stole it.

True to Megadroid's word, Neinstein was never mentioned again after the initial explanation of who he was. Only Porker Lewis ever mentioned his name despite his apparent fame.
