Amaterasu, as sun goddess and her connection to the Japanese imperial family could be considered a "main character." Epona was a horse goddess who seemed to be the pre-eminent goddess of parts of Gaul and even became popular in the Roman Empire. Atabey was the big goddess for the Tainos though shs kinda shares the stage with her husband... uh... Pre-Islamic Arabia, while generally pretty diverse, had three major goddesses who had become main figures around the time Islam was kicking off. Manat and I can't remember the other names.
Of course the big problem is the idea that religions have MCs. While certain codified, organized ones do, polytheistic religions, especially pre-modern ones, would change who was most important depending on location and time period. For example, you might consider Odin the MC of the Germanic Pantheon, but that's due to some cultural evolution and also a limited perspective. There's lots of evidence tribes predominantly considered Tyr (Teiwaz, Ziu [related to Zeus, etymologically]) to be the main god before Odin slowly usurped the position. Or while Aphrodite is mostly a troublemaker in the Athenian version of Classical mythology, the Spartans really respected her and also treated her as a war goddess and thus she was more important.
