Black Flash

Reverse-Flash's eyes nearly split open as he roared madly. The corners of his eyes burst from the strain, but flickering red lightning restored the wounds.

In his haze, Reverse-Flash saw Savitar seize him by the throat and begin running wildly. This speed had already surpassed the limits of everything Reverse-Flash had once imagined. In an instant, they broke free of the limits of dimensions and space-time, entering an azure passage.

Generally speaking, red lightning was considered the slowest. The closer it came to blue, the faster it became. Once it reached white, it meant directly surpassing the speed of light and entering the superluminal stage.

If white carried traces of gold, its implications were even more terrifying.

Of course, Reverse-Flash's research into the Speed Force had not gone that deep. He only knew that red was the slowest and blue the fastest. He had no clear understanding of speeds that surpassed the seven common colors.

If one carefully counted the Flash's many Doppelgangers in
