10 Biggest Fan Service Moments In Marvel Movies
4. "I Can Do This All Day" - Captain America: Civil War
Throughout the MCU, Steve Rogers has always been known as the Avenger who never gives up.
Ever since coming out of that lab as a super soldier in the First Avenger, his role as Captain America has always been about never stopping the battle until they've truly reached the end. While many would point to Cap's tenacity in Endgame as the greatest example of his endurance, there's something to be said about his standoff with Tony Stark in Civil War.
Doing everything he can to protect Bucky, Steve finds his disagreements with Stark kicked into overdrive when Tony unleashes on Bucky for having killed his parents. Though you know in the back of your mind that they're probably not going to kill each other by the end, the beauty of this standoff comes when Steve utters "I can do this all day" after getting beaten down time and time again.
Given that this was the last solo movie that Steve would get during the MCU, it's nice that we at least get a callback to the very first fight he had in that alley before he actually turned into the soldier we know today. No matter how much you might be willing to wail on Cap time and time again, the amount of perseverance that he has to get the job done is summed up perfectly in this one line.
