9. President Reagan in Dark Knight Returns

Wouldn't be one of these lists without at least one US president. And this isn't the only president on this list, but we'll get to that when we get to it.

For now though, let's talk about The Dark Knight Returns. DKR is pretty good and arguably set the precedent for Batman vs Superman fistfights for the rest of time. But why are they fighting? Because Superman is a personal soldier for President Ronald Reagan, acting as the US's greatest asset and not-so-secret weapon.

Miller draws Reagan as a desiccated corpse of a man, the ultimate personification of the dying government of DKR's America. For how little he actually appears in the book, Reagan feels like a huge presence in Dark Knight Returns, mostly through his influence over and puppeteering of Superman.

Miller tends to write him as a doddering, slightly goofy old man, because his political beliefs have never been exactly subtle, but it's an interesting depiction nonetheless.
