Marvel surprised fans by including a trailer for Doctor Strange in the Multiverse of Madness as Spider-Man's second post-credits scene, and it reveals a character we’ve been waiting for: Strange Supreme.

Because Doctor Strange seemed so villainous in Spider-Man: No Way Home, is it possible that Strange Supreme was actually impersonating the Doctor Strange we know and love? We don’t yet have an answer, but we’re sure to find out in the upcoming Doctor Strange film.

However, some Marvel fans are already familiar with the evil Doctor Strange lookalike. In Episode 4 of the Disney+ animated series What If…?, we meet Strange Supreme. In an attempt to bring back the love of his life, Christine Palmer, Strange Supreme goes back in time to O’Bengh to learn how to bring her back.

He absorbs every mythical creature across the universe, which turns him into a darker, more powerful being who causes his universe to descend into nothingness.

In the Doctor Strange in the Multiverse of Madness trailer, Rachel McAdams also appears as Christine Palmer, so it’s very likely we’ll get a similar backstory in the upcoming sequel. Could we see a face-off between Doctor Strange and his evil multiversal twin, Strange Supreme? Or has his evil twin already hijacked the MCU?

Doctor Strange in the Multiverse of Madness is set to release in theaters on May 6, 2022, and Spider-Man: No Way Home is in theaters now.
