HYDRA

The history of HYDRA in the MCU is, basically, a long history that’s full of twists. But I guess this is what happens when two super-secret organizations, both super-powerful, battle it out for about 70 years.

But the biggest (big screen) retconning for HYDRA came during The Winter Soldier events, when it was revealed that the organization had infiltrated S.H.I.E.L.D. ever since WWII ended. Thus, carefully, the villains led the respectable leaders of S.H.I.E.L.D. to do their own dirty work.

It isn’t just that, though. The Winter Soldier also revealed that HYDRA was infiltrated everywhere, from the leader of their counterpart organization to the American Senate, and so on and so forth. Which changed the viewer’s perspective on some other events as well – for example, Senator Stern wanted Tony’s Iron Man suit not to protect the USA, but to equip HYDRA with a most powerful weapon.

Fortunately, this twist played very well. Much better, in fact, than other twists on this list. The Russos did a great job with The Winter Soldier and the Civil War, and they will keep this trend well after the Infinity War ends.
