Reader's Guide
The Global Defense Agency is the central governing body for superhuman affairs on Earth, functioning as both a military force and a regulatory commission.
Origins and Early Heroism
Mark Grayson's journey begins not as a seasoned warrior, but as a seventeen-year-old whose latent Viltrumite heritage suddenly awakens. As the son of Debbie and Nolan Grayson—better known to the world as Omni-Man, Earth's most powerful protector—young Mark adopts the moniker Invincible upon manifesting his abilities. His initial foray into crime-fighting quickly integrates him with the Teen Team, a group comprising Robot, Rex Splode, Dupli-Kate, and Atom Eve, who become his closest allies during this formative period. Simultaneously, he encounters Allen the Alien, an operative for the Coalition of Planets dedicated to safeguarding worlds from cosmic threats.
The Omni-Man Betrayal
In a shocking display of brutality, he systematically executes Earth's premier superhero team, the Guardians of the Globe, leaving the world unaware of the massacre until Mark discovers the truth. When Nolan attempts to recruit his son into the Viltrumite Empire, Mark refuses, sparking a cataclysmic battle that leaves thousands of civilians dead and nearly kills Invincible himself. Despite Mark's love and the influence of humanity, Nolan is unable to bring himself to kill his offspring and ultimately departs Earth.
Rise of the Global Defense Agency
Following the devastation caused by Omni-Man's betrayal, Mark Grayson shifts from an independent vigilante to an operative under the Global Defense Agency (GDA), led by Director Cecil Stedman. Under Cecil's strategic direction, Robot assembles a new iteration of the Guardians of the Globe, integrating members of the Teen Team alongside new recruits like Monster Girl and the resurrected Immortal. The GDA becomes central to managing emerging threats, including the multiversal schemes of Angstrom Levy, whose vendetta stems from Mark's interference with his alternate selves. As the agency navigates these crises, they face external pressures from the Viltrumite Empire, which appoints Mark as Earth's subjugator after he aids in saving Thraxa.
Cosmic Threats and Multiversal Warfare
Major foes include Angstrom Levy, who uses portal tech to merge his intellect across dimensions; aided by the Technicians after death, he returns to attack with evil alternate Invincibles. The Viltrumite Empire also looms as an existential danger, sending enforcers like General Kregg and Conquest to force Mark's compliance or kill him. Conquest's savage hit on Earth leaves Oliver wounded and Atom Eve injured, pushing Mark into a last stand that fells Conquest, though Cecil quietly keeps the body for intel. The plot also uncovers ancient Viltrumite history, introducing the Scourge Virus that wiped out much of their population centuries ago.
