One of the oldest tropes in any superhero medium, or any storytelling medium in general, is making the hero face and defeat a dark reflection of themselves. Every Superman needs a Bizarro, every Flash needs a Reverse Flash, and every Scott Pilgrim needs a Nega Scott.
As fun as this twist can be, the whole 'evil twin' angle can become trite and clichéd fast. At this point, it's become over-saturated and all too obvious. A villain who looks like the hero but acts in the opposite way has been done an inordinate amount of times. Frankly, there are more interesting ways to do a good bad guy.
However, this cliché is so ingrained in storytelling that sometimes it happens completely organically, without anyone noticing. An arch-nemesis doesn't have to look like our main character in order to reflect their personality, after all.
The following is a look at ten heroes and villains who mirror each other in ways that are more subtle than you might expect. Whether they are a thematic antithesis of a superhero's morals, or a meta examination of a character based on backlash from readers, each of them has something to say about the hero they go up against.
