The Shadow was created by Walter B. Gibson, and long before he appeared in movies and television, he was a staple of radio. HIs first appearance was in the 1930’s, and he’s had a huge influence on heroes (and villains) to follow.
For instance, the origin of Marvel Comics’ Iron Fist and Doctor Strange are remarkably similar to the Shadow’s, as is the that of Batman (from the Christopher Nolan movies) though the way he’s often depicted in the comics is very much in line with the Shadow as well.
The Shadow was Lamont Cranston (and Ken Allard, depending upon whether we’re talking about radio, television or novels. This idea of identities within identities is very similar to how Marvel’s Moon Knight has been portrayed), young wealthy man about town though having spend time in mysterious Asia gained the ability to cloud men’s minds.
Yet, can even the Shadow and all his mysterious powers stop a man with the ability to control Time?
