Reverse Flashpoint (Earth-Prime)

"I would not create a perfect world just to watch it die. As a matter of fact, the only thing that is set to expire is you. And do you know why? Because I finally did what I set out to do all those years ago. I killed you as a child. You can do that all night long. But the fact remains, at the stroke of midnight, my timeline will solidify... And you will cease to exist. And your precious Speed Force cannot help you now, because in this timeline, she chose me. And Iris chose me. I've won. I finally won. Who's faster now?"

- Eobard Thawne to Barry Allen

Reverse Flashpoint was an alternate timeline that was created by Eobard Thawne when he traveled back to several different points in time so that he could usurp Barry Allen's role as the Flash. However, with Damien Darhk's help, Barry ultimately prevented Reverse-Flashpoint from ever happening.
