[2020] End Credits scene! who do you think will be there?

So, for Marvel movies and games ( since spider-man did it too) end credits scenes are a given.

We know that AIM and MODOK are campain focus... we know of some possible future vilains from data mining. so what you guys expect from end credits?? who you think it will be there?

who comes next as a big threat for endgame and after launch content?

Also besides who do you think it will be there.... who would blow you away if it was there??

For me I think Ultron is a given considering all the "bot plot" from AIM.. he could easely take over. Also we know Hank Pim is in the main story as suport.. so might be a link there.

it would blow me away if after Cap comes back in the end of the game they go to his grave to check it out and it's a Skrull there! it would probably be to early for that but still.. would be nice.
