The original Guardians of the Globe was a private organization funded by War Woman and Darkwing. This version of the Guardians was a pastiche of DC Comics' Justice League of America, with each of the Guardians having an obvious JLA analogue. Robert Kirkman, in his author notes for Invincible: The Ultimate Collection, Volume 1, explains that he went with these archetypes because he had only 18 pages to get the reader to care for the characters before their brutal deaths. Along with Black Samson, the team included: the Immortal ; Darkwing ; War Woman ; a Russian named Red Rush ; Aquarus, the King of Atlantis ; Martian Man ; and the Green Ghost. Omni-Man, although never an official member of the team, was a trusted associate of the Guardians, and knew the location and password of the Guardians secret headquarters in Utah. This trust let Omni-Man betray and murder the Guardians, after calling them to their headquarters on an emergency. The only member of the Guardians to survive the massacre was Black Samson, who was not actively a member at that time. The Immortal subsequently returns to life due to the nature of his power.
The new Guardians of the Globe
After the murder of the original team, the United States government re-established the Guardians of the Globe as a state-funded agency. This new team was led by former Teen Team leaderRobot, under the direct supervision of Donald, the government's superhuman liaison. Donald was ultimately responsible to Cecil Stedman. Along with Robot, the initial lineup for the new team included Dupli-Kate and Rex Splode from the Teen Team, Monster Girl, Shrinking Ray, and Black Samson, the only surviving member of the old team. The new team's performance in its first few months did not live up to expectations of its superiors, leading Donald and Cecil to make some changes. Bulletproof was added to the team's roster, and the newly resurrected Immortal was brought in as a consultant to improve standards. After the team continued to under-perform, the Immortal replaced Robot as team leader. Although not actually a member himself, Invincible reports to the same agency and often helps the team in dire circumstances. When most of the Guardians' most powerful members were sent into space to thwart a Martian invasion, they were successful, but while they were away, the team's weaker members were required to stop the Lizard League's plot to take command of nuclear warheads. Dupli-Kate and Shrinking Ray were killed by the villain Komodo Dragon; Rex Splode was badly injured in the fight, but survived. After lashing out at Allen the Alien, the Immortal realized just how deeply he had been affected by Dupli-Kate's death and resigned from the Guardians. However, it was revealed that Dupli-Kate was still alive, as she had always left her "Zero" behind on missions.
Parody team and Mini-Series
On March 15, 2010, Image began releasing teaser posters announcing members of a new Guardians of the Globe team as a parody of Marvel's advertisements for the line ups of their revamped Avengers, New Avengers, Secret Avengers and Avengers Academy books.

In an interview with Comic Book Resources, Kirkman explained that although the later images were deliberately farcical, the campaign was intended to announce a six-issue miniseries spinning out of Invincible. The miniseries, he said, would deal with the earthbound characters of the Invincible universe, while that title focused on "The Viltrumite War", an eight-issue storyline that would be set solely in space. The six-issue series, named Guarding the Globe, was launched on August 25, 2010. The Parody Team was featured in a one-page backup in the first issue. On March 21, 2010, Image began releasing teaser images of the team's real members done in the same style as the parody images. This set of posters, in order appearance, were:
