The Canadian government's own superteam known as Alpha Flight first debuted in the pages of Uncanny X-Men during the '70s, though when the team began to appear in its own ongoing series, it's history with Department H was expanded and the team continued to grow and evolve over the years.
Alpha Flight itself went through a number of roster changes and reboots that brought quite a few different members on to the team over the years that have included supervillains, American costumed heroes, and even the X-Men's Wolverine, which can sometimes make it difficult to determine which version of Alpha Flight is the best.
10 Beta Flight
Alpha Flight first debuted as Department H's elite team of Canadian superheroes, however, it was eventually revealed that Alpha was only one of a few different Flights that worked and trained with the government.
Beta Flight was considered the trainee version of the team, where members like Puck and Marrina served before joining Alpha Flight. Beta Flight would eventually be sent on their own missions with team members like Purple Girl, Talisman, Goblyn, and Witchfire, though a number of members moved through Beta Flight over the years.
9 Omega Flight I & II
Jerome Jaxon was in command of the Flight program before he was fired, and he blamed team leader Guardian for the loss of his career which inspired him to form his own team of powered characters known as Omega Flight.
The first version of the team featured former Beta and Gamma Flight members like Diamond Lil, Flashback, Smart Alec, and Wildchild, though a second villainous team of original characters was later put together by the Master of the World to also take down Alpha Flight.
8 Omega Flight IV
A new version of Omega Flight was put together by Department H and sent to investigate the site of an Origin Bomb that landed in Regina, Saskatchewan and began to dramatically transform the area and inhabitants.
The team was comprised of Validator, Wendigo, Kingdom, and Boxx, though all members of the team were killed and Validator was altered by the Origin Bomb into a powerful protector of Earth's evolution, though she disappeared after helping the Avengers during Time Runs Out.
7 The Flight
The very first grouping of Canadian heroes by Department H predates the establishment of Alpha Flight and its various training tiers and was known simply as the Flight, which came together to take on Egghead and his Emissaries of Evil.
The Flight was led by Wolverine before he abandoned the Canadian government to go work with the X-Men and featured new members like Smart Alec, Groundhog, St. Elmo, Stitch, and Narya, who would go on to become Snowbird as a member of Alpha Flight.
6 Sasquatch's Team
After most of the original members of the team were captured by an alien race known as the Plodex, Walter Langkowski/Sasquatch took it upon himself to form a new team of young Canadian heroes as the next Alpha Flight.
New members like Yukon Jack, Puck's daughter Zuzha Yu, elderly superhuman Centennial, and legacy hero Major Mapleleaf joined alongside former Flight member Nemesis and the Plodex known as Mar, though the eventual return of temporal clones of the original team led to this roster's disbandment.
5 Gamma Flight
Gamma Flight was originally the introductory level of the Flight program, where recruits like Diamond Lil, Madison Jeffries, and Wild Child began the training that would allow them to move to Beta and Alpha Flight.
After Gamma Flight became an official government team, the name was used years later by members of the original Alpha Flight team like Puck and Walter Langkowski/Sasquatch alongside characters like Absorbing Man, Titania, and Doc Samson who came together to bring in the Immortal Hulk.
4 Omega Flight III
After the death of Alpha Flight and the following superhuman Civil War and the formation of the Fifty-State Initiative, a number of heroes headed to Canada and began to work with Department H as a new heroic version of Omega Flight.
The team is comprised of American heroes like USAgent and Arachne along with Beta Ray Bill as they joined Sasquatch, Talisman and a new Guardian (Michael Pointer, who was responsible for the death of the original team as the Collective) as the short-lived successor to Alpha Flight.
3 '90s Team
Department H fell under the control of a few shady characters in the '90s, which led to the debut of a new team of Alpha Flight that included new members alongside what appeared to be classic members of the team with a few twists.
Heather Hudson returned to her Vindicator role alongside Puck and an actual Sasquatch (not Langkowski), with new members like Murmur, Radius, Flex, and a teenage James Hudson/Guardian who was eventually revealed to be a clone of the original.
2 Alpha Flight Space Program
Alpha Flight was given a new mission and a new leader when the organization was transformed into the Alpha Flight Space program, which backed up Captain Marvel aboard an orbital space station that protected Earth from cosmic threats.
While much of the support staff were military or scientists who worked for the new organization, former Alpha Flight members like Puck, Sasquatch, and Aurora would join Captain Marvel in space as her main strike team.
1 Classic
The most well-known line-up of Alpha Flight was the original team's expanded roster, which included James Hudson/Guardian, Sasquatch, Northstar, Aurora, Puck, Snowbird, and Marrina who all appeared in Alpha Flight's debut issue.
However, after the death of James, Heather Hudson took over the role of Guardian and then Vindicator and led the team, which continued to add members like Box, Windshear, and Talisman before the death of the main team, though temporal duplicates were eventually brought to the mainstream timeline to reform the team's best roster.
