UNCANNY X-MEN #286 (MAR 92)
Colossus is stunned to be reunited with his brother Mikhail, who explains that his death was staged before the Russian government sent him to this world, and how he ended up sealing the portal at the cost of the lives of people he had come to care about. On Earth, Xavier & Forge confer with some of the world's top minds trying to close the portal, to no avail. Inside the void, Mikhail refuses to use his energy manipulation power to shutdown the portal a second time, which an enraged Colossus views as an act of cowardice. Meanwhile, an enthralled Archangel leads the Posse Comitatus against the rebels, including Mikhail and the X-Men, now joined by Iceman and Sunfire. When Colossus is threatened, Mikhail is driven to action. Realizing the growing portal threatens his brother as well as everyone else, he works in concert with Sunfire, Iceman and Jean to use his power to both close the portal and send the X-Men home, while keeping everyone else alive on the other side. The act nearly kills him, however, but Colossus revives his brother, who is stunned to learn they have a sister while wondering if Colossus and his friends do this sort of thing every day.
