Mephisto will have a major story in Agatha All Along and the MCU and this is now confirmed by Marvel Studios! Agatha Show-runner Jac Schaeffer has confirmed that Mephisto isn't just a wink and nod but is an actual story. Mephisto connects to Doctor Doom, the Scarlet Witch, Doctor Strange and so many more Marvel characters in the history of Marvel Comics. This is why Mephisto is a perfect character to introduce in the MCU, and given all the Mephisto theories from Wandavision, Agatha All Along is the perfect show to introduced him officially in.
