Mephisto has finally arrived in the MCU in the final episode of Ironheart, and in his conversation with Riri, he emphasized that there were many who made a deal with him, including some famed historical figures like William Shakespeare and Ringo Starr.
But were there Marvel characters who made a deal with Mephisto? Apart from Robbins and Riri herself, there could have been others from the MCU’s past who might have done it, even though it was never revealed on-screen.
List of Marvel characters who might have made a deal with Mephisto in MCU
Quentin Beck
As Mephisto’s deals have made ordinary individuals extraordinary, it seems that Quentin Beck could have done it, as indicated by his meteoric rise and his cutting-edge technologies that could rival some of the world’s greatest tech. The things Mephisto did and said in Ironheart seem to align strongly with Beck’s character.
Aldrich Killian
As he was another character who developed something extremely extraordinary despite coming from a relatively normal background, Aldrich Killian may have also engaged in a deal with the devil. The Iron Man villain was notorious and seemed extremely hard to kill. He even managed to subdue one of the strongest Avengers alone. That is no small feat without the powers of the devil behind you.
Ghost Rider
Johnny Blaze’s deal with Mephisto is a canon event. In fact, after he trades his soul to save his father, he gains his powers as the Ghost Rider. Though a new Johnny Blaze has yet to arrive in the MCU, with Mephisto now here, their stories will most likely be interlinked.
Norman Osborne
There have been more than one iteration of Norman Osborne in Marvel, but his deal with the devil is a canon event in the comics. Norman Osborne and his son, Harry Osborne, have both shown symptoms of a curse being passed down. Is this curse straight from the devil himself, or perhaps the price of all that Norman was able to achieve?
Sentry
Robert “Bob” Reynolds became the only one to survive a procedure that killed everyone else who underwent it. He, instead, gained superpowers far exceeding any previous superhero. But there came a curse with it. This sounds quite familiar to how Mephisto operates. He could have made a deal with Bob, which would have allowed Bob to survive the procedure and gain unlimited power. But it also corrupted him in ways that he could not handle.
While there could be many more Marvel characters who could have made a deal with Mephisto in the MCU, these seem to be the most likely ones. The upcoming movies and shows could reveal more about others who have done the same.
