What was Iron Man's initial position in Marvel comics?

We know that this Iron Man is getting more and more popular now. Not a few months ago, Avengers 4 attracted many people's love, and even stayed up late to watch this movie. I didn't know this movie before, but I watched it a little a few days ago and thought it was really good and worth seeing by all of us. So, we understand that Iron Man originally came from Marvel comics, so what is the status of Iron Man in Marvel comics? Let me tell you something about this. The following is my personal opinion ~

One,

First of all, his position is particularly high. The first movie of Marvel Comics was Iron Man, which became an instant hit. So Marvel Comics will focus on creating something in the The Avengers series, and then we can know how important Iron Man is. Secondly, Iron Man plays the role of threading the needle. Maybe many people will think that captain America will be more suitable, but no. Something with a sense of science and technology will be deeply liked by others.

Second,

In the past, Marvel Comics Company once released a photo, the general content of which was that there were many actors, directors and producers starring Iron Man, and the lineup was very luxurious.

Third,

One more thing is the most important, that is, who is the actor played by Iron Man, and this is the famous Robert Downey Jr., and this actor can play a vital role. He brought Iron Man back to life. Now, as soon as many people know Iron Man, they will immediately know Robert Downey Jr., which is very valuable and deserves our appreciation.

Overall, Iron Man is very important in Marvel comics.
