Grace

Stepping onto the page in X-Men #92 in 1999, Grace is a Marvel character who made her entrance at a genuinely electric moment in mutant history, sharing adventures with heavy hitters like Wolverine, Ororo Munroe, and Cal'syee Neramani. Born of the Modern Age and brought to life by the creative team of Terry Kavanagh, Alan Davis, and Jeff Johnson, she moves through the pages of X-Men and Uncanny X-Men in some very distinguished company indeed. Her catalog footprint is small and mysterious — just three appearances — which gives her a rare, elusive quality that makes digging into those issues all the more rewarding for the dedicated collector.
