Kevin Feige's MCU kicked off the episodic side of Phase 4 with what could arguably go on to remain Marvel's most accomplished episodic effort, "WandaVision," and fans have been eagerly anticipating the reality-breaking drama's direct follow-up set to center on Agatha Harkness, Kathryn Hahn's purple-hued witch. Unfortunately, as we recently reported, Marvel made some big schedule changes, and not only was the spinoff's premiere pushed to pre-Halloween 2024, but the project now has its third official title in "Agatha: Darkhold Diaries." And while it would be easy to assume that the relatively frequent name changes are worrisome, I’m wondering if there’s a deeper canonical meaning behind it all.<br /><br />More specifically, I’m playfully theorizing that Agatha’s nomenclature fluidity is less an issue of Marvel execs jumping (and swapping) the gun, and more the machinations of a comic book character that was front and center for a hellscape of "WandaVision" speculation: the demonic shapeshifter Mephisto. Though all the conversations and questions about Mephisto were seemingly for naught when it came to Elizabeth Olsen and Paul Bettany’s one-season series, fans quickly shifted those ideas over to Agatha’s spinoff, given its presumably more direct ties to supernatural and evil entities.
