In Secret Wars Doctor Doom will be the villain, RDJ is he already in the cast as Dr. Doom. King Thanos could also appear, he is the biggest threat in the multiverse.

@Paperinick King Thanos isn't canon to the MCM yet. He's a part of Disneyland's Avengers Campus.

Although I wonder how they would go about making him canon to the MCU if they decided to do that

Well, he could easily appear in MCU, because Dr. Strange told to Tony that there is only one possibility among the millions of other possibilities to win Thanos. King Thanos is a variant of Thanos who win the Avengers and became King of the whole universe. So it is very possible that we will see King Thanos. Or we can also see him in What if...? maybe.

Cool idea

@Paperinick Very cool idea.

@Paperinick But didn't Endgame tell us that Thanos just wanted the snap and would stop there and go into retirement and such)

@Lepracaun @Paperinick is talking about a completely different variant of Thanos. Not the Thanos from the MCU.

@RJ Plotner Oh, Ok, thanks for clearing that up

Lepracaun, King Thanos' story in comics is this I tell. I put some ideas to fit in MCU but his story is real. Also in the post says about Infinity Stones and we tell about King Thanos😂.
