Back in July, we found out that the comic book series Civil War II and Invincible Iron Man would introduce Riri Williams, a 15-year-old MIT student set to succeed Tony Stark as one of Marvel's biggest superheroes. Today we've learned, via Wired, that Riri will not go by the handle Iron Man but will rather dub herself Ironheart.

Following the Riri reveal, Fuse had a long chat with Marvel editor-in-chief Axel Alonso, who was tight-lipped about the eventual moniker. "All I'll say is the book is called Iron Man," he said. "The question will be: Will someone like Riri embrace the title 'Iron Man'?"

The Invincible Iron Man cover at right is one of five STEAM-themed variant covers; also in on the stunt are Spider-Man and Gwenpool.

Writer Brian Michael Bendis explains the Ironheart group editorial decision to Wired:

“Iron Woman seemed old fashioned to some. Iron Maiden looked like a legal nightmare. And Ironheart, coined by Joe Quesada, after I told him my planned story for Riri, speaks not only to the soul of the character but to the Iron Man franchise as a whole. Tony first put on the armor to save his heart. Riri puts it on for different reasons altogether but still heart-related. When people see her story, you’ll be amazed at how simple and brilliant Joe’s suggestion was.”

We're guessing we'll have to wait at least a few issues, if not a bunch of issues, to see where Ironheart leaves Iron Man himself. But Wired says "Riri’s in-armor A.I. will based on Tony’s own personality." Meaning, as editor Tom Breevort puts it, “Regardless of where he might be physically, he’ll be soaring along with her spiritually.”
