A/N: these 3 characters are my guesses on who the next big threat in the mcu will be now that thanos is gone. And when I say big threat, I mean that in terms of a threat that all the heroes or a majority of heroes will have to deal with.

Here's my 3 guesses.

Dr. Doom.

Galactus.

And this last one I think is a little more possible than the other two.

Annihilus.

Austin: I think we all know Annihilus wasn't even given a reference in Endgame.
