Hawkeye's lack of powers and screen time has made him an underestimated hero in the Marvel Cinematic Universe. Despite this, he has proven time and time again that he is a vital member of the Avengers. He has provided guidance and support to the team and has become a father figure to some. It is also because of him being one of the few non-enhanced heroes that he has become relatable and likable to audiences. He is a constant reminder to fans that no matter how powerful a character is, they could be a source of guidance and support, even without powers. This is a role that Hawkeye has adopted in the MCU and one that can shape the future of the franchise.
