This week on What If...?, an evil Doctor Strange is taking center stage, and a new poster hypes his arrival. Marvel's current Disney+ series is taking a unique approach to telling its story. Instead of focusing on the universe fans know and love, What If...? explores alternate timelines within the MCU. For example, the first episode imagined a Captain America: The First Avenger where Peggy Carter took the super-soldier serum, while last week's plunged viewers into a world where the Avengers were killed before they became a team.

Each What If...? installment has approached its alternate timelines in different ways, and it'll be interesting to see how episode 4 proceeds. Not much is known about this Wednesday's episode, save that it will center on Doctor Strange. A plot synopsis revealed weeks ago hints at the story that lies ahead for What If...?'s version of the character. Instead of taking an honorable path after discovering the mystic arts, Doctor Strange will reportedly slip into darkness. In other words, he's turning evil.

Much as it has over the past few weeks, What If...? has unveiled a brand new poster to set the stage for its next episode. The sheet reveals "Doctor Strange Supreme," a crueler looking version of the character with a new, sharper costume. Even without seeing him do any magic at all, this Doctor Strange looks far more powerful and terrifying than the one fans first met in his 2016 solo movie. Check out the poster below.

While What If...? episode 1 essentially was only a remake of a particular MCU movie, episode 2, which centered on Chadwick Boseman's T'Challa, completely reinvented the Marvel universe by applying one small change to the Black Panther character. What If...?'s Doctor Strange episode has the potential to do the same with the sorcerer, though it seems likely that his change will result in a far darker MCU. After all, the name Doctor Strange Supreme suggests he'll reach the absolute height of his powers, but he might not be using them for good.

Despite initial reports saying otherwise, Benedict Cumberbatch will voice Doctor Strange for the What If...? episode. This comes ahead of his back-to-back appearances in Spider-Man: No Way Home and Doctor Strange in the Multiverse of MadnessThe latter movie will similarly see Doctor Strange reach a new level of skill, so this week's What If...? can give fans a preview of what's to come. Hopefully, though, he'll remain a good guy in the main MCU, if only to keep the universe from total destruction.
