Uncanny X-Men #284

On the Sakhalin Islands, Sunfire meets with government officials from Japan and Russia to deal with a massive, sealed crater on the island. While investigating, Sunfire uses his powers on the cap to the crater. The crater changes into a void and knocks out Sunfire. Three figures emerge from the void and kill everyone else. Nearby, the X-Men are on their way home from their latest battle when they receive a distress call. They reach the island and engage in battle with the aliens. However, Storm realizes that the aliens are fighting to protect the crater. The aliens are defeated but one of them reveals that they were not here to kill mindlessly, but to protect the X-Men’s world from the void. With that said, the void opens and sucks in the X-Men, while Xavier and Forge escape. Meanwhile, Bishop, Malcolm and Randall begin to hunt down the criminals from the future. Unfortunately, the men have no other choice but to kill the criminals, who refuse to turn themselves in, which are all of them.
