Storm first appeared in 1975 in the comic book "Giant-Size X-Men" #1, written by Len Wein and pencilled by Dave Cockrum. In this comic, Wein uses a battle against the living island Krakoa to replace the first-generation X-Men of the 1960s with new X-Men. Storm was an amalgam of two characters Cockrum created: The Black Cat and Typhoon. The Black Cat had Storm's costume, minus the cape, and was submitted for the new X-Men's original lineup. However, during a hiatus in the new X-Men project, other female cat characters like Tigra were introduced, making the Black Cat redundant.
