In the year of 2640, Eobard Thwane inherited a virtuous amount of wealth from his family; this would help fulfill his life long dream to be a Flash. One day, Thwane passed an antique shop and saw the Cosmic Treadmill. Instantly recognizing it, he bought it immediately and tried to duplicate an accident that would turn him into the Flash. However, the planned accident didn't go as planned and left him scarred and mentally unstable. At the chance of having his face rebuilt, he has it look exactly like Barry Allen, his idol of his entire life, and the hospital expenses cost him the rest of his fortune. This did not matter as he now had a chance to be his revered idol's partner. He attempted to travel back to the past and leave his time impatiently. However, the Cosmic Treadmill had not been used for many years and resulted in it breaking down. As a result, the Treadmill miscalculated the desired time at which Thawne wanted to travel, and sent him a few years after Barry's death in Crisis on Infinite Earths. Disorientated and disillusioned from the rough time travel, Thwane saw many posters of Barry Allen killing a man known as "Professor Zoom". The poster revealed the man's name as "Eobard Thawne". Thwane's mind snapped and he became psychotic. This resulted in him becoming evil.
