Tempo

Heather Tucker is a mutant who first appeared as a member of the Mutant Liberation Front, a militant group fighting for mutant rights by violent means. Over time she affiliated with other mutant factions, including the Acolytes and later the Marauders.

Born into the Copper Age revolution that Rob Liefeld and Louise Simonson were cooking up in 1990, Tempo made her Marvel debut in the pages of The New Mutants #87 — one of the most collector-celebrated issues of the era — and has quietly endured for over three decades since. She's the kind of character who rewards deep-dive readers, turning up across Marauders, Trials of X, and X-Factor and sharing panels with heavy hitters like Wolverine, Psylocke, and Bishop along the way. With 38 catalog appearances stretching all the way to 2023, she's no footnote — she's a persistent presence woven into the fabric of the X-Men corner of the Marvel Universe. If you love discovering the layered, sometimes overlooked figures who give that world its texture, Tempo is absolutely worth your attention.
