Dr. 13

A skeptic in a world that refuses to stay rational, Dr. 13 made his Bronze Age entrance in The Phantom Stranger #34 in 1974, brought to life by Steve Skeates and Tony DeZuniga. He's the kind of DC character who earns his keep precisely because he's surrounded by the uncanny — sharing pages with the Phantom Stranger himself, as well as figures like Prince Amentep and Misty Kilgore — yet apparently remains unconvinced by all of it. Across a remarkable 44-year publishing span stretching into 2018, he's turned up in Grant Morrison's ambitious Seven Soldiers universe alongside Zatanna, cementing his place as one of DC's more fascinatingly contrary presences. If you love a character who stands his ground against the impossible, Dr. 13 is absolutely worth tracking down.
