even if they introduced Doom next year, let's say in Deadpool 3....., it will take like 5 to 7 years to get the proper movie with him or the secret wars or something.....
we would still have to wait like half a decade or more to get an " infinity war" type movie for doom.
and I don't see anything changing in the Disney leadership to guarantee a good Doom 10 years from now ...... we would be in our 50s by the time they use Doom if they don't bring him now .... if Kang is the villain for the next 5 years, then Doom would be fully use 10 years from now? ( I know I'm not using the correct timeline, it's just an example)
kang is proving to be a disappointing character, Doom could be the next Thanos,
