Uncanny X-Men #164

The X-Men aboard the Z'Reee Shar are under fire from Brood warcraft while fleeing Sleazeworld. Wolverine realizes they carry Brood embryos, and the Brood won't kill them. Kitty goes on a spacewalk to repair the ship, while Carol Danvers unleashes new powers to fight off the Brood. Meanwhile, Professor X struggles with despair, believing the X-Men are dead. Carol repairs the warp drive, but Colossus’s invitation to join the X-Men is declined. Storm discovers life growing inside her, and Carol’s Binary powers trigger explosive decompression aboard the ship when she blasts off without opening the hatch.
