I started this discussion in another thread, but I seriously wonder if in 2030 whether World War II will be a feasible birthplace for characters not named Steve Rogers. Natasha, Fury, Magneto and Xavier (who is dead) and Juggernaut are all tied to history that is rapidly fading away.
Magneto became a Holocaust survivor about the time the movies are using him now. When his character was roughly 40-50s. In 2020 the youngest he could possible be without de-aging is 78-77ish and that really robs him of any memory of the camps. Even with the de-aging the timeline is becoming strained. One thing I suppose is you could kill him and bring back the O5 Magneto through time.
I also wonder if future generations will view those eras the same way, or whether they'll be more fascinated by other eras like the tech boom, or something. I liked how Ultimates did their own thing with Magneto. Some hated that, but I liked it.
There are more characters like this as well including the Zemos, Zola, Sabretooth (slow aging I assume), Pietro and Wanda were alleged to be born after the war.
Do you think eventually Marvel will have to move into a more modern era and abandon some past ties. This seems like it'll eventually have to be addressed.
