In the early 1980s, adventures of Storm written by Claremont included a space opera arc, in which the X-Men fight parasitic beings called the Brood. Storm is infected with a Brood egg and contemplates suicide, but then experiences a last-minute save by the benign whale-like Acanti aliens. Storm's fellow X-Man Angel is abducted by a rogue mutant group called the Morlocks. The X-Men are outnumbered, and Storm is rendered sick by the Morlock called Plague. To save Kitty's life, Storm challenges the Morlocks' leader Callisto, in a duel to the death for the leadership of the Morlocks. Despite being violently sick, she defeats Callisto by stabbing her with a knife. Callisto is saved through the efforts of a Morlock healer, and Storm offers the Morlocks refuge at the Xavier Mansion, though they decline.
