Gaia

Emerging from the late-1990s Marvel Universe courtesy of Larry Hama and Terry Dodson, Gaia made her debut in Generation X #38 (1998), stepping into one of the era's most compelling corners of the X-Men world. Her time in the spotlight was brief but memorable, sharing pages with a stellar cast that includes Jubilee, Monet St. Croix, Jonothon Starsmore, and the formidable duo of Sean Cassidy and Emma Frost. With only a handful of catalogued appearances, she's a genuine rarity — the kind of deep-cut discovery that makes longtime Generation X fans feel like true insiders.
