Breakout young hero Riri Williams armors up and takes center stage this April in IRONHEART: BAD CHEMISTRY, a new one-shot by Hugo-and Eisner-winning writer John Jennings and all-star artist Jethro Morales

Ironheart’s latest solo story will reintroduce KHEM, a deadly new villain Jennings co-created with artist Paris Alleyne in 2023’s Free Comic Book Day: Marvel’s Voices #1.

Kicking off when Khem steals a legendary Marvel artifact to upgrade her already formidable alchemy-based powers, this thrilling rematch will shed light on Khem’s origin and cement her as Riri’s fiercest adversary.

She’s already attacked Chicago once and made off with a valuable artifact from the DuSable Black History Museum.

Now the alchemical transformer Khem is back for another bite of Ironheart’s city — and this time, she’s not alone.

What is Khem’s connection to a classic Iron Man villain — and can Riri stop her before all of Chicago burns? It’s an action-packed flurry of blows in the Windy City!
