It’s complicated about rumor

1. Yes, Inhumans will be added to "Doctor Strange in the Multiverse of Madness" page if Black Bolt appears in that movie.

2. About the Vulture and Morbius thing, I don't think they're gonna in that movie.

Morbius has nothing to do with the MCU. It isn’t even part of the MCU’s canon.

Also DON’T USE GOOGLE CAST LISTS.

I could care less about Morbius since it is the worst superhero film of 2022. Surprised you actually saw it after an F score most people dodge those films because they are not worth it. Enough about stupid Sony Pictures. Anyway, Black Bolt isn't confirmed yet though Marvel's Illuminati has been brought up and Black Bolt is an original member.

1. It's a popular rumour that this will happen. Specifically Black Bolt. Not sure about the rest. How likely it is, I'm not sure. I'm confident that other people know a possible answer better than I do.

2. Vulture and Morbius are very, very unlikely to appear in MoM, as it stands.

@SSBFan33 I actually really enjoyed and thought it was good. But I also really loved Eternals and Inhumans which seem to be very unpopular opinions
