After they incapacitate Alpha Flight, Colossus finds Northstar overdosing on the mutant drug, Banshee, resulting in him being crippled from the waist down. In the alternate future of "", Northstar is one of many members of the staff of the Xavier Institute. He briefly survives the destruction of it and several surrounding miles, only to die in Scott Summers' arms. As he passes on, he sees a vision of his Alpha Flight friends, leading is his sister, who encourages him to leave his body. In the alternate reality created by the Scarlet Witch known as House of M, Northstar is an agent of S.H.I.E.L.D., responsible for training a squad of young mutants and superhumans in the agency's junior training squad program. Much like the rest of the super-powered community in House of M, Northstar supported this reality's Magneto and his mutant-supremacy platform. In the alternate timeline seen in the "Age of X" storyline, Jean-Paul was on the first team of Fortress X defenders to attack Kitty Pryde when she breached the barriers, while Jean-Paul wants revenge for his sister's murder. In What If Scott Summers and Jean Gray Got Married Sooner?, their leaving inspired the rest of the original X-Men to leave the X-Men as well and seek lives in the outside world. Professor X recruited Northstar as part of a new team, along with Aurora, Storm, Colossus and Catseye. This new team unfortunately died fighting the living island Krakoa. Sunfire and the Avengers defeated it, and found their bodies. In What If Wolverine Was Leader Of Alpha Flight?, Northstar was responsible for Wolverine staying in Canada after his capture by government forces. This story diverged from the story in X-Men 120–121, where Alpha Flight was assigned to capture Wolverine and return him to the service of Canada. As in the mainstream reality, the X-Men (Cyclops, Nightcrawler, Storm, Colossus, Banshee and their associate Colleen Wing) flew off, but here, Wolverine did not escape custody and slip aboard the plane. They circled back to attempt a rescue. The Canadian government tried to call Alpha Flight to handle things before they were forced into military intervention, but Northstar was on monitor duty and refused to take the call (presumably in anger that Cyclops had just beaten him in combat before Wolverine surrendered). Left with no other alternative, the Canadian military shot the X-Men down. None of them survived the crash.
