Cylla Markham

Cylla Markham made her entrance into the Marvel Universe in 1990's Uncanny X-Men #261, courtesy of the legendary creative team of Chris Claremont and Marc Silvestri — a pedigree that signals serious Copper Age business. Affiliated with the Reavers, the Sentinels, and even the X-Men themselves, she occupies a fascinatingly tangled corner of the Marvel universe, sharing pages with heavy hitters like Lady Deathstrike, Donald Pierce, and Yuriko Oyama. Her small but notable footprint — capped by an entry in the Official Handbook of the Marvel Universe: Wolverine 2004 — marks her as exactly the kind of deep-cut character that rewards dedicated collectors hunting the edges of the X-Men mythos.
