Eobard Thawne (Earth-1: Pre-Crisis)

Professor Eobard Thawne (born c. 2151) is the arch-enemy of the Flash and the time criminal known as the Reverse-Flash.

Early life
At some point around 2151, Eobard was born and in a distinguished family and grew up studying astro-navigation. Eobard had become aware of his family's history during his youth to the point that he knew his ancestor Eddie Thawne that was so much of a failure that they was no record of him. In his adulthood, Eobard became a scientist and spent his life studying the Speed Force and unlocking the ability to become a speedster.

During his studies, he became obsess with the Flash to the point that he managed to time travel back in the 21st century to meet him only to discover that he was destined to become his arch-enemy. At some point during his time-travels, he gained possession of Gideon, an AI created by the Flash, and used it to guide himselve.
