As we approach Marvel Phase 6, Kevin Feige says that Marvel plans to include Sacha Baron Cohen's Mephisto in the MCU going forward.
"He was never part of WandaVision. We've talked about that. Matt's talked about that. Jack Schaefer's talk about that. He was never part of WandaVision," Feige explained at a press conference attended by GamesRadar+, when asked whether Mephisto was supposed to make an earlier debut in the MCU. "But the enthusiasm with which he was theorised on that was certainly cool and fun to watch. And he's another character that, pre-MCU, would have been hard to do. He's a devil. How do you do that character? But he's a formative character. He was a big part of Thanos' storyline in the comics. So again, now that he's here, the potential is clear."
