Megara Is a Young Yzma
The theory that Megara from Hercules is a younger Yzma from The Emperor’s New Groove is a sprawling one. The original post lasts multiple pages, and uses actual mythology on top of Disney lore. Basically, this theory argues that Yzma was a lovesick Hades worshipper that left the Incan Empire and lived the plot of Hercules. Following that, actual Greek mythology kicks in and Hercules is responsible for the death of his and Meg’s kids. After that, she’s saved by Hades, pushed to madness, and returns to Peru.
