Domino

Debuting in the pages of Marvel Holiday Special #1 in 1991 — courtesy of creators Danny Fingeroth and Ron Garney — Domino has been a compelling presence in Marvel's mutant universe across more than three decades of Copper and Modern Age storytelling. She's carved out a niche in some of Marvel's most action-charged corners, appearing most prominently in X-Force and The New Mutants, and sharing countless adventures with heavy hitters like Cable, Cannonball, and Sam Guthrie. With five key-issue appearances to her name and a catalog presence stretching all the way to 2024, she's no background player — she's a character with staying power and real collector significance. If you're building out your Marvel mutant reading list, Domino is absolutely worth tracking down.
