Tabitha Smith

Tabitha Smith is a mutant who ran away from her abusive home life as a teenager, eventually falling in with various X-affiliated groups. She possesses the ability to generate explosive plasma 'time bombs,' and has operated under several aliases including Boom-Boom, Boomer, and Meltdown.

Tabitha Smith burst onto the Marvel scene in 1985's Secret Wars II #5, a Bronze Age debut courtesy of Jim Shooter and Al Milgrom that launched one of the more enduring young voices in the X-Men corner of the Marvel Universe. Over four decades — and 264 catalog appearances spread across X-Force, The New Mutants, and X-Factor — she's proven herself a genuine fixture, sharing countless adventures with the likes of Sam Guthrie, Roberto Da Costa, and the wider mutant ensemble that defines Marvel's most passionate corner of superhero storytelling. With 19 key-issue appearances to her name and a publishing history stretching all the way to 2026, Tabitha is far more than a supporting player — she's a character whose longevity speaks for itself. If you're building a serious Marvel collection or diving deep into the X-Men's rich Bronze and Modern Age history, she's absolutely worth your attention.
