Elysia

Elysia made her entrance in the pages of Marvel's X-Men #100 in 2000 — a milestone-numbered issue that collectors already had circled on their want lists — brought to life by the legendary Chris Claremont alongside the breathtaking linework of Leinil Francis Yu. She's a Modern Age creation who shares her pages with a remarkable roster including Kurt Wagner, Colossus, Neal Shaara, and the formidable Domina, placing her squarely in the thick of late-era X-Men drama at its most ambitious. Her appearances are few and carefully placed, which gives each one a certain weight — the kind of character whose scarcity only sharpens a completist's curiosity.
