Megan Gwynn

Few characters introduced in the Modern Age have taken root quite as deeply as Megan Gwynn, who made her debut in New X-Men #15 in 2005 under the creative hands of Christina Weir, Nunzio DeFilippis, and Paco Medina. Over more than two decades of publication — spanning X-Men, New Mutants, and Legion of X — she's grown from a newer face in Marvel's mutant world into a figure with genuine staying power, racking up 138 catalog appearances and three collector-significant key issues along the way. She's kept remarkable company throughout, sharing pages with heavyweights like Wolverine, Scott Summers, and Ororo Munroe, which says everything about how central she's become to the X-Men corner of the Marvel Universe. If you're building out your Modern Age mutant collection, Megan Gwynn is absolutely worth tracking down from the very beginning.
