In the Technet's first recorded exploit, they were hired by Sat-Yr-9, the Earth-794 counterpart of Opal Luna Saturnyne, to hunt down and bring back Kaptain Briton. Kaptain Briton fled to Captain Britain's Earth, fought Captain Britain and switched costumes with him, thereby deceiving the pursuing Technet, who then mistakenly took Captain Britain prisoner. The Technet brought Captain Britain to Earth-794 where Captain Britain convinced the Technet that he was not the man they had been hired to capture, and the Technet joined Captain Britain in battling the angry Sat-Yr-9's troops. Captain Britain returned to his own Earth, where his sister, Psylocke had killed Kaptain Briton when he attempted to assault her.

Later the Technet went to the Wereworlds that were inhabited by people who would turrn into werewolves under a full moon. On the planet Elmo one of the members was fatally wounded and died. Gatecrasher either seriously injured or killed a member of the 'Berserker Pirates' who attempted to interest her in becoming his lover. The pirate's family forced the Technet to turn over all their accumulated wealth as reparations. Angered by this reversal in their fortunes, all of the members of the Technet except for Yap and Fascination, later known as Scatterbrain, left the team.

Gatecrasher then went to a celebration held by the despot of Kandahar. A person she believed to be the despot himself hired her to procure a perfect mathematical model of the universe that was made of rock crystal and that was held and revered by the Incas of 14th century Peru on Earth-616. Gatecrasher, Yap, and Fascination journeyed through time to obtain the model, but Gatecrasher and Yap were tricked by the person they believed to be a native high priest into consuming fruit filled with the eggs of deadly parasites. Gatecrasher and Yap were thus forced to remain under a cooling waterfall to prevent the eggs inside them from hatching and consuming their bodies from within. In actuality, an alien had impersonated both the despot of Kandahar and the high priest, and hoped to force Fascination into his employ through this convoluted plot. This alien had already succeeded in hiring the members of the Technet who had just left the group. His team was the Special Executive, a future version of the Technet. The team's precognitive told him that Fascination wouldn't join the Special Executive for another 300 hundred years.

Fascination brought Captain Britain and his companion Meggan to 14th century Peru to rescue Gatecrasher. Captain Britain gathered together the plants necessary to create the antidote that would kill the parasite eggs. Gatecrasher and Yap consumed the antidote, and then they, Fascination, Captain Britain, and Meggan returned to their own time period.

Gatecrasher recruited new members Numbers and Waxworks and all the former members except Elmo rejoined.

Opal Luna Saturnyne hired the Technet to capture Rachel Summers who, according to Saturnyne, was a threat to the universe. At the time Rachel was on the run from Mojo who had enslaved her to star in his movies and had sent the warwolves after her.The Warwolves and the Technet fought over Rachel and during the fight, Ferro 2 was killed. Rachel was saved by Captain Britain, Meggan, and her fellow X-Men Nightcrawler and Kitty Pryde. Together they fought off the Technet, with Gatecrasher feeling for her life, who then retreated. This battle against the Technet led directly to the formation of the team Excalibur by Summers and her allies. It was later revealed that Saturnyne had hired the Technet under orders of Roma, who needed to form the superhero team to save the multiverse.

The Technet were allowed to stay in Brighton, England, where they would use their alien technology to provide the city with sunny weather. Meanwhile they would plot to capture Rachel Summers and regain their honor. During this time, they were hired by Sat-Yr-9, who had taken the identity of Courtney Ross. The Technet were hired to free Jamie Braddock. They succeeded in their task, but Jamie was taken by Ross and the Technet's memories of their mission were wiped. Gatecrasher then constructed Hardboiled Henry, a living bomb, to ambush Excalibur. The plan succeeded and the Technet nearly defeated Excalibur, but agents of Saturnyne interfered. The Technet received a holographic message from Saturnyne, telling them that they were permanently exiled to Earth-616 and that the bounty on Phoenix was canceled. Furious the Technet turned on Gatecrasher, but Gatecrasher and Yap teleported away. The Technet begged Excalibur for asylum and Nightcrawler told his teammates to accept. The former Technet repaired the damage done by Hardboiled Henry to Excalibur's home. During these repairs Numbers met the dragon living in Excalibur's basement and fell in love with her. The British government came to Excalibur's home for help against an invisible, murderous creature, but only Nightcrawler was home, nursing a broken leg. Nightcrawler trained the aliens to become the N-men and they managed to destroy the creature, but Joyboy disappeared during this mission. Shortly afterward the Special Executive appeared on Earth and told the N-men that they had predicted Earth's destruction to happen within the next few hours. They offered the N-men a job. The N-men agreed and teleported away, together with Numbers, the dragon and their newly born children.

Excaliber were able to prevent Earth's destruction and found Joyboy with the Crazy Gang. Here Joyboy had formed a psychic bond with the Crazy Gang's Red Queen, using his powers to distort her nightmares and form a beautiful land. During this time, Gatecrasher began to go insane, seeing images of Hardboiled Henry, who accused her of making his death meaningless.

The Technet later reappeared. In this appearance Gatecrasher was the leader once more and Joyboy and Hardboiled Henry had returned as well. Roma had hired them to capture Franklin Richards. Fantastic Four and the Roma came to a agreement and Technet disappeared.
