Professor Zoom

"Her hero. How noble. Oh, wait. You didn't stop JFK from getting assassinated or make sure Hitler stayed in art school. You saved your mommy. You missed her. And in a supreme act of selfishness shattered history like a rank ametuer, turned the world into a living hell moments away from destruction and I'm the villain?"

- Thawne explaining how Flash caused an apocalpytic war while saving his mother in the process.

Professor Zoom, also known as Reverse-Flash is the arch-nemesis of the Flash. He is a twisted sociopathic criminal with a brilliant mind and super-speed. Eobard Thawne was born in the 25th Century and travels through time to do battle with his most hated enemy. He has also been a member of the Secret Society of Super-Villains. He is considered to be the evil version of the Flash.

Early Life
Eobard Thawne was born in the 25th Century. His parents genetically engineered him to be highly intelligent and to have a particular appearance. However, as he grew up, they become concerned about his lack of social skills and tendency to daydream, which was frowned upon in a their very regimented society. Hoping that helping to take care of a sibling would help Eobard adjust, his parents had a second son, Robern. Eobard struggled to manage his little brother and he would be reprimanded by their parents for yelling at him. Eobard spent so much time in social bonding sessions and psychological analyses with Robern that he fell far behind in his own studies. As a result, his application to study the Speed Force at the Flash Museum was rejected. Eobard illegally began doing his own research on the subject. However, he was caught by Robern, now an officer in the 25th Century Police Force. Eobard found a spare Flash costume in a time capsule. Eobard amplified the suit's energy and discovers its power as he began wearing the suit and began feeling the speed and power and Eobard sees himself that he is the opposite of the Flash. In the process, Eobard reversed the colors of the costume, the suit becoming yellow and the boots, lightning bolt highlights and earwings are now red and the white circle emblem is now black. Eobard goes by the name, "Professor Zoom" as he continues committing crimes.

The Flash TV series
Zoom appears as the main antagonist of The Flash.

One of the main characters, Harrison Wells' mysterious endings have shown indications of him being the Reverse Flash, such as him faking a wheechair and at the end of the midseason finale, he had the Reverse Flash suit, and an evil smirk and in the same Reverse Flash distorted voice, he says Merry Christmas.

This has triggered a lot of debate, even to the point of wondering why Reverse Flash spared Eddie Thawne's life.
