Previously, there were reports that Robert Downey Jr. and Tony Stark will be giving up on the red suit and will pass the baton to a 15-year-old. Afterwards, there were reports that 'Iron Man 4' is not happening, but recent developments seems to suggest that another Avenger will be wearing the Iron Man costume.

In the comic books, Tony Stark aka the Iron Man passed the baton to a 15-year-old Riri Williams, and many believe that this may well be the plot for the upcoming 'Iron Man 4'. However, this will involve introducing a new character to an iconic cinema superhero-something that can be risky.

However in the comic books, it is not only Riri Williams that has donned the Iron Man suit.

But Riri Williams is not the only lucky one to wear the Iron man metal suit. There's one character that's totally unexpected what could play the Iron Man in 'Iron Man 4'.

As reported by Christian Today, it seems that Natasha Romanoff (played by Scarlett Johansson) known for her role as the Black Widow will be the Iron Man in the upcoming 'Iron Man 4'. So I guess, they should call the character Iron Woman?

According to the report, in the comic books, Tony Stark lend his suit for the Black Widow and that she got to wear it a couple of times too many.

However, this is not the first time that Tony Stark has lend his Iron Man costume. Actually he lends it quite a lot, and I don't think that Tony Stark lending that suit would mean that he is giving up on being Iron Man; although, with Black Widow's skills, it would be interesting to see her in that suit in 'Iron Man 4'.

Despite the rumors, Robert Downey Jr. still hopes to play the role of Iron Man, the actor added,

"I don't know how long I'll do it for... I'll keep playing Iron Man for a couple more years, I guess."

Additionally it was RDJ who confirmed that 'Iron Man 4' is happening back in his interview in Ellen DeGeneres show last 2014.

For now what we know for sure is that we'll be seeing RDJ as the Iron Man until Avengers: Infinity Wars Part 1 and Part 2.
