9 Villains We’re Still Waiting To See In The Arrowverse

8) Shade

First of all, we have to admit that Shade has previously appeared in one episode of The Flash. However, it was such a loose and underwhelming version of the character that it hardly counts as an adaptation of one of the most long-running and significant foes of the Scarlet Speedster in comic book history.

Dating back to 1941, Shade has fought Jay Garrick, Barry Allen and Wally West over the years. Originally a thief with the power to manipulate shadows, he was rebooted in the 1990s to be a much more morally-ambiguous character – a Victorian man granted immortality who became the mentor to Starman.

Despite his long and interesting history, the character made his live-action debut in season 3 of The Flash… and was portrayed as a complete non-entity. Just some dude who could turn into a shadow and was easily defeated by the STAR Labs gang. With the concept of the Multiverse at its disposal, though, a much more comics-appropriate version could easily show up in the future, as he could be said to be a doppelganger from another Earth. If Arrow can have two different versions of Count Vertigo, The Flash can definitely have two separate characters based on Shade.
