The way I see it, rivalries are either based on how the fans portray them, or are intentional. For example, Sonic the Hedgehog was intentionally made as a rival to Mario (and started out that way), and Marvel and DC are two of the biggest comic book publishers in the world. Other times it's mostly just fanbase vs. fanbase.
