Every Major MCU Movie Twist Ranked Worst To Best

Big big twist that changed everything came during the sixth MCU movie to feature Iron Man. Since Iron Man number 1, the death of Tony Stark's parents remained as a black cloud over the character's head, but at no point was a conspiracy suspected until Helmut Zemo's callous reveal in the final act of Civil War: Bucky Barnes murdered Stark's parents.

It goes without saying that this had big implications. But the one thing more harrowing than Bucky's involvement was the realisation that Steve Rogers had known this simple fact for longer than he cared to let on, possibly ever since he got the dossier on Bucky at the end of Winter Soldier. In an movie that pitted good guys against more good guys, viewers were truly caught between a moral rock and a hard place, while Cap and Iron Man fell out hard and beat each other almost to death.

This down and out turn of events in the good guy saga of the MCU came about through one sneaky and utterly gripping twist. It was also one of the many treasured accolades brought to the MCU by the Russos.
