Cordelia Frost

Cordelia Frost is a younger sister of Emma Frost, born into the wealthy and deeply dysfunctional Frost family. She moves in the orbit of mutant affairs largely through her complicated ties to Emma and their siblings.

Cordelia Frost stepped onto the Marvel stage in 1995's Generation X #8, courtesy of Scott Lobdell and Roger Cruz, arriving as part of the famously complicated Frost family — a clan whose pages she shares with Emma, Adrienne, Winston, Hazel, and Christian Frost. Her appearances span an impressive eighteen years across titles like Generation X, Emma Frost, and Wolverine & the X-Men, making her a quietly persistent thread woven through some of Marvel's most compelling mutant storytelling. She may not boast a towering appearance count, but any character who keeps company with Emma Frost and endures across nearly two decades of the Modern Age clearly has a hold on the Marvel universe worth investigating.
