ALTERNATE VERSIONS
In the Age of Apocalypse, Aurora and Northstar were part of Mr. Sinister’s Elite Mutant Force (E.M.F.) and, as such, were assigned to patrolling the breeding pens. The siblings were rather 
snotty about their superior status as mutants and seemed to take great pleasure in punishing those prisoners who acted up or tried to escape. When the E.M.F.’s leader, Cyclops, switched sides, secretly helping some inmates to escape, he was caught in the act by the speeding twins. Still, the one-eyed Summers managed to take both Northstar and Aurora out before they could report him. In fact, he rendered the twins comatose, keeping his betrayal secret for the time being. The twins were cast into the role of outlaws when Apocalypse's rule ended and a democratic system was re-installed. Magneto and his X-Men promised to hunt down all mutants that had worked for Apocalypse, and eventually Weapon X and X-23 found and killed the speedster twins.
Jeanne-Marie never joined Alpha Flight in the reality shown in What if (2nd series) #60. The original X-Men having disbanded much earlier - due to Scott and Jean getting married, Xavier had to look for new mutants and recruited both Aurora and Northstar before they would have been contacted by Alpha Flight. Along with them were also Storm, Colossus and Catseye. As this team was still somewhat inexperienced, Xavier accompanied them when he picked up a powerful signal from the mutant island, Krakoa. The entire group was defeated within minutes and, as Xavier was among the captured people, nobody realized the X-Men’s disappearance until it was too late. By the time the Avengers were alerted to the danger of Krakoa and had defeated it, the new X-Men’s bodies had already been drained of all their energies.
In a variation of the alternate future timeline known as Days of Future Past, Jeanne-Marie once again became a nun following Northstar’s death, and was living in a convent in Lourdes, France. 
When most of the X-Men were killed or captured by operatives of the Weapon X program, Wolverine assembled a new team, for which he also recruited Aurora. However, because of the overwhelming odds they had to face, Logan preferred her third, rather violent personality, to be in control, and slapped Jeanne-Marie several times, thus provoking the personality switch. The third personality still had no name, and was only referred to as “her”, both by Logan and by herself. Unfortunately, five years later, these new X-Men were ambushed by Agent Zero, and Aurora was either seriously injured or killed.
In the Ultimate universe, Alpha Flight was an internationally-supported team of mutant operatives localized in Canada's Department H, in response to America's relationship with the X-Men and Ultimates. Aurora was a member of Alpha Flight and was in opposition to her brother Northstar's attempts to avoid being recruited.
Alpha Flight attacked the Xavier Mansion when the X-Men were playing baseball with Jean-Paul's school, the Academy of Tomorrow. Aurora and her teammates kidnapped Northstar and prepared to experiment on him using the power-enhancng drug, Banshee. Several X-Men, including Northstar's boyfriend Colossus, took Banshee themselves to come and rescue him from Department H.
In the second Heroes Reborn universe, the unchecked imperialism of the Squadron Supreme of America made the American - Canadian border one of constant strife. They annexed Alberta and British Colombia and bombed the rest of the nation as a show of force. The Blur killed Aurora's brother Northstar during the conflict, and even Weapon X temporarily killing Hyperion didn't make up for it. Alpha Flight became fugitives in their own country as the occupying American forces hunted them down. Hyperion's need for vengeance was relentless once he returned from the grave. Eventually, Sasquatch betrayed Aurora and the others, setting up Logan for Hyperion. In exchange, the Squadron kept their occupied territories and abandoned the rest of the Canadian wasteland of a country for Aurora and Alpha Flight to rebuild as they saw fit.
