Meet Riri Williams. She's a teenager black girl from Chicago, a science genius who enrolls in MIT at 15 and she will be taking Tony Spark's place in the Iron Man series using a suit that she built herself by reverse-engineering one of Stark's old model armors.

Impressive!

Williams' first appearance was in this year's Invincible Iron Man #7. According to writer Brian Michael Bendis, the story is about "a brilliant, young woman whose life was marred by tragedy that could have easily ended her life — just random street violence — and went off to college.”

Bendis thinks that Williams' story was the most modern version of a superhero or superheroine story he's ever heard.”

He anticipates mixed reactions from fans, saying "there are fans who say, 'show us the new stuff,' and then there are fans who say, 'don’t do anything different from when I was a kid.' So when you’re introducing new characters, you’re always going to have people getting paranoid about us ruining their childhood."

And he's right.

Some fans welcome this new plot in the series.

I LOVE THAT THE NEW IRON MAN IS A BLACK GIRL. I'm here for Riri Williams

Marvel Comics: "Iron Man as a black woman would be dope."
Black Woman: "I would love to write —"
Marvel: "We have white people for that."

Others have started speculating who would play her role should she be part of a Marvel movie.
