Marvel Studios used to be the undisputed champ of giving major characters a proper introduction. Now we get THIS.

Fans have been wondering if/when/how the devilish character would ever arrive onscreen since the premiere of WandaVision four and a half years ago, and Ironheart creator Chinaka Hodge tells Entertainment Weekly that the decision to include that long-awaited moment in this series was not hers "alone."

"I was empowered by Marvel to make that decision," said 'Ironheart' showrunner Chinaka Hodge, but admitted she doesn't know Mephisto's return.
