Superman: Red Son
Superman Alternate Universe
Red Son is one of my favorite alternate universe stories. This "What if?" story is written by Mark Millar. If you don't know already it is a story about Superman landing in the Soviet Union instead of the United States. I won't give too much away if you haven't already read the graphic novels but you can view the Red Son motion comic movie here and find other merchandise including the graphic novels.
DC comics and Marvel both have Stories of different realities or a multi-verse. You might actually get to enjoy them more than the original.
What if? Scenarios
Imagining these things always appealed to me. There's no telling how many stories you can come up with for a character if you shape his past differently or change a decision he/she makes. If you have a favorite What if or alternate story let me know in the comments below, it doesn't have to do anything with comic books.

Superman Landing in Russia changes not only his story but other heroes as well. If you like the Motion Comic Movie you will most definitely enjoy reading the graphic novel with much more of the story than you get from the movie.
