Iron Man Has Never Won A Battle On His Own Before Avengers: Endgame BY THOMAS BACON – ON JAN 05, 2019 IN SR ORIGINALS Iron Man Avengers Endgame
Iron Man may be Marvel's flagship hero - but, ahead of Avengers: Endgame, it's surprising to note that he's never actually won a battle on his own. When Stan Lee originally created Tony Stark, it was because he wanted to see if he could turn somebody everyone should dislike - a greedy, self-absorbed capitalist - into a superhero.

That's why the basic structure of the Iron Man films has always remained the same; Stark tries to do it on his own and fails, but by the end of the movie he has his friends and allies with him, and thus wins
