MCU: 10 Worst Things The Avengers Have Done

Steve Rogers and Tony Stark have had a rollercoaster of a relationship since first meeting in Avengers Assemble. The latter heard all about Captain America from his dad growing up, but when they finally met, Tony couldn't see what all the fuss was about.

While they may have gotten off on the wrong foot initially, the two became close friends throughout their time with the Avengers, saving the world together. Until the civil war. As Tony himself tells Bruce in Infinity War, he and Cap fell out hard, and it was all Cap's fault.

As if it wasn't horrible enough that Tony found out the man Cap had been protecting was the same man who killed his parents, the fact that Steve knew it and kept quiet was adding insult to injury. Stark had every right to feel betrayed by God's right hand man, and his former friend.

Steve Rogers is usually the epitome of everything that is good and right, but keeping this life-changing secret and protecting the man who killed Stark's parents was something almost unforgivable. Though Tony was eventually able to put this behind him, it took seven long years before he could speak to Steve again.
