An initial line of update comics introduced Redmond and Blutarch Mann as the rival CEOs behind the Gravel Wars, whose father, Zepheniah Mann, wrote them out of inheriting Mann Co. after they convinced him to spend a fortune on a series of useless gravel plots in New Mexico. The family's remaining wealth instead went to Zepheniah's maidservant, Elizabeth, while the company went to his Australian bodyguard, Barnabus Hale. The gravel plots were split between the brothers to ensure they would continue their senseless rivalry after Zepheniah's death. The Administrator is characterized as a shadowy manipulator responsible for prolonging the Gravel Wars into the game's present day of the 1960s, with Redmond and Blutarch exploiting Australium, a gold-colored miracle metal and nuclear superfuel, to build and power life-extending machines to live well over a hundred years each. Australia itself is an advanced global superpower due to its discovery of the material, with a population obsessed with manliness and physical combat as a result of their exposure. Mann Co. is in turn inherited by Barnabus's grandson, globe-trotting adventurer Saxton Hale, who gladly provides weapons for both sides of the Gravel Wars. The
Mann vs Machine storyline introduces Gray Mann as the third Mann brother, who was abandoned at birth and raised by eagles before returning with the intent of world domination at the end of the Gravel Wars. Gray kills the senile Redmond and Blutarch before building a robot army to take over Mann Co., leading Hale to rehire the RED and BLU mercenaries for the ensuing Robot Wars. The fictional history of the
Team Fortress universe was compiled in the "Catch-Up Comic", which retroactively set
Team Fortress Classic in the 1930s and 1940s, featuring an older, tactical "Team Classic" preceding the modern Team Fortress. Team Classic is in turn preceded by an 1800s Team Fortress hired at the outset of the Gravel Wars, featuring
Billy the Kid (Scout),
Stonewall Jackson (Soldier),
Abraham Lincoln (Pyro),
Alfred Nobel (Demoman),
John Henry (Heavy),
Nikola Tesla (Engineer),
Sigmund Freud (Medic),
Davy Crockett (Sniper) and
Fu Manchu (Spy). Other comics promote the seasonal
Scream Fortress and
Smissmas events, the former introducing the character of Merasmus, a powerful wizard.
#1: "Ring of Fired" Facing defeat in the Robot Wars, Gray invokes a clause Hale had written into the position of CEO, stipulating it could be obtained by anyone who bests him in single combat. Gray instead presents his secret eight-year-old daughter, Olivia Mann, as the challenger, forcing Hale to resign upon being unable to harm a small child. The two Manns try to access Mann Co.'s store of Australium to power Gray's own life-extending machine, only to find the Administrator had been using the conflict as cover to repossess it for her own ends. Six months later, Miss Pauling sets out to recollect the mercenaries for a final job from the Administrator. She tracks down Soldier, Pyro, and Demoman after Soldier frames his former roommate Merasmus for the murder of
Tom Jones.
#2: "Unhappy Returns" Hale reunites with his ex-lover and former adventuring partner, Maggie (Mags), to defeat Gray. Demoman and Soldier rescue Scout and Spy from hanging for their mercenary activities in the town of
Teufort, New Mexico. Pauling finds a birth certificate for Helen, the Administrator, at the Teufort library and destroys it.
#3: "A Cold Day in Hell" Soldier, Scout, and Pyro track Heavy to the
Dzhugdzhur Mountains in Siberia, where his family has been hiding from the authorities for years. Heavy's sister Zhanna falls in love with Soldier, and the family decides to end their exile and travel the world once Heavy is paid for the job. Gray Mann hires Team Classic, led by the Classic Heavy and recently joined by the modern Medic, to take down the Administrator.
#4: "Blood in the Water" The team travels to Australia, which has been left in disarray by the recent loss of their natural Australium veins. Heavy and Scout run into Hale and Mags, Soldier, Zhanna, and Spy steal a submarine, and Pauling and Demoman track down Sniper. Pauling reveals to Sniper that he is one of the sole survivors of New Zealand, a
Krypton-like lost civilization beneath the
Pacific Ocean that is home to the last unclaimed Australium cache. The team travels there, only to find Sniper's irresponsible birth parents had squandered the entire cache with no knowledge of the material's power. Team Classic attacks, shooting the Sniper and capturing the others.
#5: "Old Wounds" The team is taken to Gray's private island for interrogation. The Classic Heavy turns on Gray, ripping the life-extending machine out of his spine and leaving him to die with the prisoners. Soldier and Zhanna break out and rescue Pauling, however not until after she is tricked into revealing the Administrator's location. Gray warns her the Administrator's plans for the Australium are likely far worse than his, but she dismisses this as he expires. Medic revives the Sniper with science, explaining he only joined Team Classic for the medical funding, and is reprimanded by the Classic Heavy after Sniper escapes. Classic Heavy reactivates Gray's robot army, including a new type of robot designed to siphon out the trace amounts of Australium found in Australian people's bloodstreams.
#6: "The Naked and the Dead" Demoman defeats the blood-sucking robots by inflicting them with alcohol poisoning and Medic performs emergency blood transfusions on the other mercenaries. Heavy, Scout, Hale, and Mags parachute in with the team's weapons to fight off the other robots as the Classic mercenaries are picked off one by one. Spy admits to being Scout's father while disguised as Scout's idol, Tom Jones. Classic Heavy kills Medic and uses Gray's life-extender to overpower the enraged modern Heavy in a fistfight. The Medic outsmarts the Devil in a deal, allowing him to return to life where he bluffs the Classic Heavy long enough for the life-extending machine to be ripped out of him. The Classic Heavy dies, but the machine's Australium charge is already used up. The Administrator is revealed to have been using her own life-extending machine at the attendance of the Engineer. Learning the mission is a failure, she uses the last of her Australium in a single dose, reversing her age to that of a young woman but ensuring her death within the hour.
#7: "The Days Have Worn Away" Helen is born sometime in 1800s America, and as a child witnesses the murder of her parents at Zepheniah Mann's behest. As an adult, she poses as a governess named Elizabeth, intending to kill Blutarch and Redmond, but finds Zepheniah in fact values fratricide above all else, with every Mann before him having murdered his siblings to attain the family fortune. As revenge, she instead engineers the rivalry between the boys to ensure a lifelong stalemate between the two, tormenting Zepheniah with the knowledge of their inadequacy until his death. After the battle with Team Classic, Hale sets out to win Mann Co. back from Olivia and Pauling discovers a miraculous untapped vein of Australium at Soldier's hideout. She rushes a sample back to the Administrator's secret base only to discover her grand plan had only consisted of keeping a revived Zepheniah Mann alive, surrounding him with footage of the Gravel Wars to continue his torture. Helen had dismissed Zepheniah's "magic gravel" as a fool's gold, but was introduced to Australium's ressurective properties by a young Gray Mann, allowing her to revive Zepheniah and provide Blutarch and Redmond with their own life-extending machines to continue the Gravel Wars indefinitely. Realizing this, Pauling lies and says the Australium is gone. The Administrator admits she no longer remembers the cause of her vendetta, accepting her death as she and Zepheniah expire in one another's arms. Engineer offers to dispose of the cache, and Pauling accepts. Seven years later Hale and Olivia bond over a shared distaste for corporate life and agree to leave Mann Co. to be split between two rival underlings. Merasmus is broken out of prison by Soldier, but is tortured to death by the Korean mafia over a small loan Soldier had taken out in his name. Soldier is rescued by Heavy and Sniper, and reconciles with Merasmus's ghost. The team reunites at Scout's family home to wish the reader a merry Smissmas. Hale and Mags continue their adventures as seniors well into the present day. == Development and publication ==
