The original group named Gamma Flight was never shown in action, but mentioned several times by its former members and their allies. Images depicting the first team’s roster can be found in Alpha Flight (1st series) #1 and #51-52. The second incarnation of Gamma Flight first made their appearance in Alpha Flight (1st series) #1. Both teams were created by artist and writer John Byrne. The third team was showcased in Alpha Flight vol. 1 #76 (1989) and was created by James D. Hudnall.
The Canadian government would organize and create Department H, a dream project of James MacDonald Hudson. Two others instrumental members of the project and in the formation of Department H were Gary Cody and General Jeremy Clarke. Gary Cody was the program’s very first government liaison and even though Gary believed in the concept and the individuals of the super-beings found by James Hudson he was bound by his obligations to the Canadian government.
They would create a branch of teams depending on the super-beings level of powers and ranking of training. Thereby Alpha Flight, Beta Flight, and lastly Gamma Flight would be created and teamed by individuals specifically separated by how prepared they would be as operatives of the government and Alpha would be he premiere team to represent Canada.
Gamma Flight’s various members were training both individually and as a team to condition and prepare their unique powers into a tight unit which would eventually graduate into Alpha Flight. However after much deliberation with the Canadian Prime Minister he would shut down the entire Flight program due to budget constraints. Alpha Flight had made their public debut only several weeks before but, during their first battles, they had caused damages amounting to several million dollars. As a result, the parliament felt that super heroes were a concept which the government could no longer afford due to its liability and the project was shut down and its members dispersed.
The original roster would include: Diamond Lil, Smart Alec, Wild Child and Madison Jeffries. Marrina was also a member for a brief time of Gamma Flight while in training.
Some time later as Alpha Flight left the sanctioning of the Canadian government, the government decided to recreate Gamma Flight. Enlisting new members into their reformed Gamma Flight they would be used to create a new premiere Canadian team. After Alpha Flight disappeared for several months due to exploits in several dimensions, the newly created Gamma Flight was the official replacement team by Parliament. This team included: Auric, Witchfire, Silver, Nemesis, and Gamma Flight return member Wild Child.
The second Gamma Flight and Alpha Flight first met, they were in conflict; their relationship was competitive and adversarial. The two teams became allies while battling Llan the Sorcerer. However after backing Alpha Flight during a war against Llan the Sorcerer this newly created Gamma Flight was reduced as a training team yet again by the Canadian government. After Llan was defeated the Canadian government decided to finally disband Gamma Flight in a merger with Department H and Alpha Flight with many members leaving as government sanctioned operatives.
The members of this second incarnation did not fare well after they left the team. Auric and Silver would later be kidnapped by the Sphinx, and they both died while being experimented on. Nemesis would also perish as she remembered she came from an erased timeline. Along with her lover Centennial both died shortly after they were buried together. And Witchfire would take accept her heritage as daughter of Belasco, a sorcerer who formerly ruled the dimension Limbo. Witchfire becoming evil herself and battling the X-Men.
A third Gamma Flight arose under the new program operated by Department H. Gamma Flight is a categorization for the science & research inclined members of Alpha Flight.
A new Gamma Flight was formed when a number of deaths and resurrections made the Devil Hulk the dominant Hulk personality. Sasquatch created the team to compete against Gen. Fortean's aggressive Shadow Base team. The team consisted of Puck, Absorbing Man, and Titania. They were based out of Alpha Flight's space station.
Unfortunately, the team wasn't a match for Fortean. They were defeated, with Sasquatch as their only casualty. This caused Doc Samson to defect to Gamma Flight and team up with the Hulk to take down Shadow Base.
Unbeknownst to the team, the Leader had been manipulating events, including killing Doc Samson and stopping him from returning from the Below Place through the Green Door to his own body. Instead, Samson made it to Sasquatch's body becoming Doc Sasquatch.
When Henry Gyrich was assigned to lead Alpha Flight, he tasked Gamma Flight to start hunting down all gamma mutates. This caused the current roster to quit and be replaced by the U-Foes. When Hulk was attacked by the U-Foes, Puck got the team back together, with new members, to help the Hulk.
After disobeying Henry Gyrich, the members of Gamma Flight are marked as fugitives. Doc Sasquatch, Dr. McGowan, and Puck go on the run with the help of Titania and Absorbing Man's history of dodging the law, while also looking for an appropriate lab to cure and separate Rick Jones and Del Frye.
When a suspected gamma mutate named Stockpile (Gen. Fortean's daughter) made the news for lashing out in public, Puck drags the team out of the shadows to help her out. They were attacked by a re-mutated Skaar and needed to be quickly teleported. When McGowan's teleporter fails, Creel absorbs its properties and becomes a human teleporter, except he doesn't have full control and they end up in gamma version of the astral plane. From there, they figure out that Abomination is using Gen. Fortean's body to turn a Texas town into a gamma mutate research facility and mass producing a supplement called Fortify that is turning users into gamma mutates.
After fighting through gamma zombies and gamma werewolves and convincing Skaar to defect, the team used Doc Samson's old cathexis ray to reverse the effects on the test subjects. Unfortunately, it exploded before it could be used on Abomination. Creel was able to absorb its properties, but since he only had enough power for one shot, he used it on Del and Rick to separate them.
After the team was able to run off Abomination, Puck suggested they stick around the town to help people deal with the after effects of gamma mutation.
