10 Times The MCU FRUSTRATINGLY Held Back

6. The Red Skull's Relationship With Nazis

Though in the original comics HYDRA - and especially Red Skull - were deeply associated with Nazis and Adolf Hitler himself, Marvel made great strides to move away from that relationship in both the movies and TV.

Though the organisation does have ties with Nazis in The First Avenger, the Red Skull eventually denounces his former leaders and plans to attack them with his Infinity Stone-powered weapons. Consequently, instead of spending the war bringing down Hitler, Cap is mostly preoccupied with a force who takes neither side in the conflict, perhaps diluting the true horrors that occurred during the 1940s.

Also, despite leaning on iconography like the double-fisted salute, as well as sharing similar ideological goals, the relationship between HYDRA and Nazism has only been further erased in future releases.

Captain America sequels rarely brought up their role in the war - and definitely not in the same breath as the Axis forces - while an alternate-history episode of Agents of S.H.I.E.L.D., the writers made a big deal of pointing out how the two groups aren't one and the same, attempting to put an end to people conflating the them once and for all.

It's bit of a strange choice though, as Cap famously made his debut punching Hitler in the face and his role in the war defining his character for decades, and to separate him from that strips him of some real-world significance.
