There’s a new Iron Man. Well, Iron Man for now. She’s still working on the name. The events at the end of the comic-book event series Civil War II will result in Tony Stark stepping out of the Iron Man suit and a new character, Riri Williams, taking over, Marvel tells TIME. (Note: Tony’s departure doesn’t mean you know the end to Civil War II yet.)

Riri is a science genius who enrolls in MIT at the age of 15. She comes to the attention of Tony when she builds her own Iron Man suit in her dorm. Creator and Iron Man writer Brian Michael Bendis spoke exclusively to TIME about the creation of Riri Williams with comic-book artist Stefano Caselli and Marvel’s increasingly diverse cast of characters.

How did you come up with the character of Riri Williams?

One of the things that stuck with me when I was working in Chicago a couple of years ago on a TV show that didn’t end up airing was the amount of chaos and violence. And this story of this 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 was very inspiring to me. I thought that was the most modern version of a superhero or superheroine story I had ever heard. And I sat with it for awhile until I had the right character and the right place.

As we’ve been slowly and hopefully very organically adding all these new characters to the Marvel Universe, it just seemed that sort of violence inspiring a young hero to rise up and act, and using her science acumen, her natural-born abilities that are still raw but so ahead of where even Tony Stark was at that age, was very exciting to me.

What have we seen of her so far in the Iron Man comics?

In the latest issue of Iron Man, Tony is in a lab talking to himself, and he’s already aware that there’s some student at M.I.T. that’s reverse-engineered one of his old armors all by herself in her dorm room. He’s aware of her immediately.

What’s been the reception of the character so far (before this announcement)?

Thankfully because of my involvement in the creation of Miles Morales and Jessica Jones and some other characters, it’s getting the benefit of the doubt from even the most surly fans. 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.

I’ve been down this road with Miles Morales, Jessica Jones, Maria Hill. I knew I was in good hands with Mike Deodato and other artists who are helping visualize Riri.

Marvel Comics’ diverse new cast has stirred some controversy among a subset of fans.

Some of the comments online, I don’t think people even realize how racist they sound. I’m not saying if you criticize you’re a racist, but if someone writes, “Why do we need Riri Williams we already have Miles?” that’s a weird thing to say. They’re individuals just like Captain America and Cyclops are individuals. All I can do is state my case for the character, and maybe they’ll realize over time that that’s not the most progressive thinking.

But increasingly we see less and less of that. Once Miles hit, and Kamala Khan hit and female Thor hit — there was a part of an audience crawling through the desert looking for an oasis when it came to representation, and now that it’s here, you’ll go online and be greeted with this wave of love.

I think what’s most important is that the character is created in an organic setting. We never had a meeting saying, “We need to create this character.” It’s inspired by the world around me and not seeing that represented enough in popular culture.

Why did it take so long to turn the Avengers from a team of mostly white dudes into a more diverse array of characters?

Talking to any of the older creators, it’s the thing they said they wish they’d done more of — reflecting the world around them. It just wasn’t where the world was at at that time. Now, when you have a young woman come up to you at a signing and say how happy she is to be represented in his universe, you know you’re moving in the right direction.

I don’t want to spoil anything for fans …

More people are going to be upset that they think they know the ending to Civil War II now than anything we just talked about. But I can tell you just because we’re hearing what we’re saying doesn’t know you mean how Civil War II ends. We’re not telling you the end, at all.

What led Tony Stark to a place where he’s stepping out of the suit?

We’re in the middle of a very big Tony Stark storyline — actually three storylines converging. His best friend died, his company is collapsing and he’s finding out who his biological parents were all at the same time. That’s stressful for a character who is wired the way Tony is wired and has dependency issues the way Tony does.

Tony is also a master at not paying attention to the thing that’s most important and distracting himself with Avengers stuff. How that all shakes out such that Tony is no longer in the armor? You’ll have to wait to find out for the end of Civil War II. But it does create a path or Riri Williams, who Tony will know and will be interacting with very shortly in the comics.

How do they meet?

One of the things Tony does to distract himself from all the things going on in his life is he goes to find this young woman who is flying around the middle of America in an armor that’s not completely made to try to find out what her deal is.

It’s hard to subtly fly around in Iron Man armor.

You imagine that Tony has Iron Man armor on his Google Alerts.

He’s also aware that this young woman is flying by him in terms of how quickly she’s doing it. Her brain is maybe a little better than his. She looks at things from a different perspective that makes the armor unique. He can’t help but go maybe I should buy her out.
