Jean-Paul Beaubier, an Olympic and professional ski champion and mutant joins his country’s team of Super Heroes, Alpha Flight, and takes the codename Northstar. Upon joining, he reunites with his long-lost twin, Aurora, and they fight the good fight for a while until Northstar joins the X-Men and leads a team of new mutants he dubs Alpha Squadron in honor of his former glory days.
Twins Separated at Birth
Shortly after their birth in Canada, twins Jean-Paul and Jeanne-Marie Beaubier’s parents die in a car crash. Their mother’s cousins, the Martins, take them in. Unable to afford to raise both children, the Martins send Jeanne-Marie to a Catholic girls’ school; the twins grow up unaware of each other. When the Martins die, six-year-old Jean-Paul enters the foster system.
Raymonde Belmonde catches teenage Jean-Paul stealing, but becomes his mentor and guardian, helping Jean-Paul cope with his emerging mutant nature and come to terms with being gay. Belmonde introduces Jean-Paul to skiing, which becomes a passion and a means to improve control of his mutant super speed. Jean-Paul joins a circus and becomes a talented trapeze artist. He comes to regard his fellow performers as the family he had never known; however, still filled with anger and frustration, he joins the separatist Front de Libération du Québec, becoming the radical Cell Combattre’s courier. The group plants a bomb, and Jean-Paul ends up saving innocent lives, causing him to reject the Cell’s reckless methods. He then severs all ties with the Front.
Jean-Paul returns to skiing, secretly using his powers to become a famous and wealthy world champion and Olympic gold medalist. During this time, the Canadian government’s Department H forms a team of superhuman operatives, Alpha Flight. The team’s founder James Hudson, AKA Vindicator (now Guardian) notes Jean-Paul’s resemblance to the recent recruit Aurora from a photo and discovers they are siblings. The pair’s reunion comes as a surprise to all, for when they shake hands, they create a flash of intense light. Overjoyed to learn that he has a sister, Jean-Paul joins the team as Northstar to be with her, though he has little love for playing the Super Hero.
Superhuman Speed and Flight
Northstar can move and fly at superhuman speeds. He channels kinetic energy of the atomic motion in his body’s molecules to accelerate in direct proportion to the amount of kinetic energy tapped. Theoretically, Northstar could reach 99 percent of the speed of light, but his inability to breathe at such speeds and the damage his body would suffer from wind and friction prevent this. By partially robbing his molecules of their atomic motion increases the binding forces within and between the molecules, making his skin durable enough to withstand wind, friction, and air turbulence at speeds up to at least Mach 10 without injury. The Children of the Vault’s enhancements briefly increase his abilities. While carrying an unprotected passenger, Northstar does not exceed 60 mph, so that they can breathe easily; Northstar trains himself to breathe comfortably at far higher velocities. Northstar can also move individual parts of his body at superhuman velocities, for instance, to repeatedly strike an opponent with his fists at superhuman speed.
Northstar can vary his molecules’ acceleration rate to release a photon cascade as bright as a lighthouse beacon. Originally, an involuntary act precipitated by physical contact with his sister, alterations to their powers have periodically allowed each twin to generate light independent of the other. Still, the ability now appears to be reset back to its original status.
Jean-Paul is also a world-class skier and skilled trapeze artist. He is also bilingual in French and English.
Subversive Enemies
After Northstar is killed by the subversive terrorist group Hydra, they resurrect and then brainwash him to do their bidding. Though captured and held by S.H.I.E.L.D. for his protection and that of others, the Children of the Vault liberate Northstar and reunite him with his sister Aurora, who suffered trauma in the Weapon X program. The Children of the Vault experiment on them and not only briefly increase their powers, but also brainwash them into doing their bidding. They attack the X-Men to get at Victor Creed, AKA Sabretooth, but the X-Men capture them. Members of the X-Men help them heal, and they both recover.
Courageous Company
While born to Jean-Baptiste and Mrs. Beaubier, Jean-Paul grows up with his mother’s cousins, Louis and Genevieve Martin, after his parents die in a car crash. Though the Martins’ couldn’t take care of both Jean-Paul and his twin sister, Jeanne-Marie, so they send her to a Catholic girls’ school. The twins reunite on Canada’s first team of Super Heroes, Alpha Flight, and discover their powers grow stronger when they’re together. This connection, however, is later undone, and their powers operate independently. When together, they often wear matching uniforms, they grow close, and Aurora helps Northstar when he has cold feet before his wedding.
The twins join Alpha Flight alongside teammates Michael Twoyoungmen, AKA Shaman, Anne McKenzie, AKA Snowbird, Walter Langkowski, AKA Sasquatch, and their leader Guardian, on many missions, some that pit them against the X-Men. After Alpha Flight disbands, Northstar joins the X-Men and becomes a teacher of business and economics. He leads a team of new mutants that he names Alpha Squadron after his former team.
After discovering a baby in a dumpster who shows symptoms of the AIDS virus, Jean-Paul adopts her and names her Joanne Beaubier. Though she dies, Jean-Paul relinquishes his silence about his sexuality in the hopes that his homosexuality opens doors to conversations about HIV prevention and education. He later dates Kyle Jinadu. Though Jean-Paul struggles to balance his Super Hero and love life, and it impacts their relationship, they eventually work it out and get married.
