X-Men #120 (1979)
Alpha Flight is a team of superhuman Canadian operatives that originated in the private sector with an engineer named James MacDonald Hudson who had developed an exoskeleton to assist in geological exploration. When Hudson learned that the U.S. military had appropriated his invention, he destroyed the plans and made off with the helmet necessary to control the apparatus. Heather McNeil, then executive secretary to Hudson's immediate superior Jerome Jaxon, was shocked by the sudden turn of events and arranged a meeting between Hudson and the Canadian government. Hudson was able to plead his case and the government stepped in to resolve the situation. The Canadian prime minister subsequently invited Hudson to participate in the creation of Department H, a top-secret research and development agency within the country's Ministry of Defense. Hudson married Heather soon after.
Following Hudson's apparent death, leadership of Alpha Flight was assumed by his wife Heather when she donned his battlesuit and succeeded him as Vindicator. The Canadian government resumed sponsorship of Alpha Flight, and the team established a headquarters on Tamarind Island off the coast of British Columbia. However, relations between the team and the government grew strained over time. Alpha Flight's government liaison, a former intelligence agent named Gary Cody, sought to keep the team under control by resurrecting one of Hudson's earliest attempts to create a superhuman being. This creature, known as Bedlam, killed Cody before violently confronting the team. After a pitched battle, Vindicator managed to destroy Bedlam.
During one of the team's adventures in another dimension, Department H created a new team dubbed Gamma Flight to act as their official agents during Alpha Flight's absence. When Alpha Flight eventually returned to Earth, the two teams initially clashed but soon put aside their differences to oppose the threat of the extradimensional menace of Llan the Sorcerer. After Hudson returned alive and well, Alpha Flight and Gamma Flight were combined into the one team that were reinstated as Canada's official government operatives. The restructured team continued to face various threats, at one point teaming up with Wolverine against the forces of the Brass Bishop, but ultimately Department H was dissolved and the team disbanded.
Department H was eventually reinstated under the administration of General Jeremy Clarke, who was charged with creating a new Alpha Flight. The new team, which included a mixture of veterans and neophytes led by a seemingly youthful Hudson, found itself manipulated by subversive tactics and clandestine missions, including one against the X-Men. Department H's deception was not laid bare until an encounter with the remaining members of the original Alpha Flight team, including the true Hudson. The younger Guardian was revealed to be a synthetic being created to supplant the original, who had refused to rejoin the Department H and was subsequently targeted for assassination. The two teams joined forces and regained control of Department H.
Wolverine subsequently helped the reformed team against the weapon-making terrorists of Advanced Idea Mechanics, during which the team regained a former member in Snowbird but lost the younger Guardian who sacrificed his life to ensure the team's freedom. Alpha Flight returned the favor by helping Wolverine defeat the cannibalistic sorcerer Mauvais. Wolverine also briefly served as mentor to a new member, Earthmover, who was being groomed to replace Shaman on the team.
Alpha Flight's next challenge was of a very personal nature when Hudson was attacked and seemingly killed by an insane scientist Jiroult who sought Heather's affections for his own. Hudson was saved by Shaman's magic but left physically crippled. Hudson donned an experimental exo-suit to prevent Jiroult from killing Heather. He was later fully healed with the help of the X-Man Archangel. Afterward Heather gave birth to a baby girl.
The team was later charged with retrieving Canadian citizen Sammy Paré from the X-Men's home at the Xavier Institute, as the Attorney General's office, the Governor of Connecticut, and the Canadian government had deemed the school unsafe for children to inhabit. This led to a clash with the X-Men, which was quickly halted after Sammy agreed to return back to Canada with Alpha Flight.
While out on a date Mapleleaf and Puck were attacked by wax duplicates of dozens of heroes, controlled by the Manimator, whom Puck easily defeated with a left hook. Following a struggle with a mind-controlled Big Hero 6, events spiraled out of control when the team tried to use time travel to save former enemy Flashback, whose future self had been killed in a previous battle. A series of efforts resulted in history being rewritten for the worse with each change they made. Sasquatch was ultimately able to enlist the past Shaman's help in stabilizing the timeline and saving Flashback. Soon after, Centennial and Nemesis apparently perished, Mar and Yukon Jack left, and Puck and Major Mapleleaf went to reserve status.
When the Chaos King (Amatsu-Mikaboshi) began his Chaos War, he plunged the living into eternal sleep and destroyed the underworld, freeing the dead including members of Alpha Flight. The team fought against the Great Beasts who were helping to further Mikaboshi's goals, and at the end of the war Alpha Flight was permanently restored to life. Their first official act after being resurrected was to stop the anti-government fanatic Citadel along with Purple Woman, who stole a server that would allegedly expose the corrupt Unity Party led by Gary Cody in order to disrupt the Canadian election; they were defeated before the information was revealed. Later, Alpha Flight repelled an Asgardian hammer-wielding Attuma during the Serpent (Cul)'s assault on Earth and provided rescue efforts for his victims.
