Flash

Original Timeline: Having never grown up in the same household and with nothing to inhibit their romantic feelings, the original Barry Allen and Iris West fell in love and would eventually be married. At some point, Barry would join the forensics department of the Central City Police Department, and was eventually promoted as the director of the CSI division. He later created Gideon, an A.I. program. In 2020, a particle accelerator created by Harrison Wells and Tess Morgan, gave Barry the power of super speed and a connection to the Speed Force, allowing him to become the superhero known as "The Flash". Sometime after becoming the Flash, he became a founding member of an unknown organization. In the year 2024, Barry engaged in a battle with his archenemy, the Reverse-Flash, along with Green Arrow, The Atom, and Hawkgirl, in a crisis amidst the red skies. The battle ended with both speedsters vanishing in an explosion of light. Unknown to anyone, the two speedsters actually traveled back in time to the year 2000, with Barry trying to stop Eobard from killing his younger self, as the Reverse-Flash somehow discovered the Flash's real name.
