From the Golden Age to the 30th century, the Reverse-Flash and Flash mantles have been locked in a rivalry spanning numerous generations. These are the fastest, strongest, and most wicked versions of the Reverse-Flash ever to plague the Flash Family.
5) Rival

The first Reverse-Flash, Edward Clariss, aka the Rival, is always trying to prove his superiority over the original Golden Age Flash, Jay Garrick. A professor at the same university as Jay, Edward attempted to recreate the formula that gave the hero his super-speed. Upon gaining super-speed, the Rival used his powers to commit crimes and tried to kill Jay. Although the Rivalโs original super-speed formula was only temporary, he would periodically return — having regained his powers and resuming his mission to kill Jay and everyone he loves. Despite laying the groundwork for the Reverse-Flash mantle, the Rival himself never demonstrated any noteworthy feats of speed or pulled off any major crimes against the Flash Family. The original sometimes gets left in the dust.
4) Inertia

Thaddeus โTadโ Thawne, aka Inertia, is the archnemesis and clone of Bart Allen, aka Impulse. Like Bart, Inertia hails from the 30th century before travelling back in time to the modern day. Inertia was raised in a super-slow simulation to be methodical and ruthless. He was also raised to despise the Allen family, particularly Bart, and has dedicated his life to killing him. Inertia created his own version of the Rogues and briefly used the alias Kid Zoom while serving as the sidekick for another Reverse-Flash, Zoom. Inertia is continually working to destroy Bartโs loved ones, including his girlfriend, Valeria Perez, and the Teen Titans. A sadistic and cunning brat, Inertia makes it painfully clear that the feud between the Allen and Thawne families is destined to last centuries.
