Over our summer break, I was reading a book whose protagonists traveled to alternate universes which, frankly, I didn’t like very much. But it did get me thinking about the idea of alternate universes in fiction. Not the scientific concept of alternate (parallel) universes—though that’s often the subject of many sci-fi stories—I’m talking about the alternate universes that result from one thing changing in a fictional story. What if Charles Xavier died before he could found the X-Men? What if Captain America was a Nazi? Undoubtedly, a lot of things would be bad. And unfortunately, this is the kind of alternate universe that we often see in today’s fictional media. However, the idea that one different thing could change everything is so broad that I don’t understand why this kind of grimdark change is the most common. Fanfiction also often deals in alternate universes which diverge from canon, but the changes of fanfiction, on the whole, all tend to be more positive and more emotionally satisfying. Though many mainstream movies and TV shows disdain this sort of happy story, an alternate universe which changes originally negative canon material into positive new story fodder can bring with it a wide range of different emotions than the usual grimdark reboot is capable of.
