There are plenty of characters in the Marvel canon that we’ve yet to see in the Marvel Cinematic Universe, either on the big or small screen. And with the way that the Marvel Cinematic Universe is heading, it isn’t a surprise that some of the lesser-known heroes are beginning to make appearances—like Simon Williams, a.k.a. Wonder Man, who first appeared in 1964 but has taken breaks and not been a focal point of Marvel comics. He’s certainly not the first character you’d think of when someone says Marvel, but he is important for where I think Marvel is heading.

And now the Marvel Cinematic Universe has announced a Wonder Man series that is heading to Disney+, from Shang-Chi and the Legend of the Ten Rings director Destin Daniel Cretton. But fans of the Marvel Cinematic Universe are probably wondering who Wonder Man is, and given what we know of Marvel’s upcoming plans, it isn’t that surprising for him to make an appearance.
