The Secret Invasion storyline was the masterwork of writer Brian Michael Bendis, who had been planting the seeds for the event for several years, most notably within the pages of New Avengers. The core eight-issue limited series, which ran from April to December 2008, was illustrated by Leinil Francis Yu, with inks by Mark Morales and colors by Laura Martin. The event was designed as the culmination of a “trilogy” of major Marvel events penned by Bendis, following House of M and standing alongside the thematically linked Civil War (written by Mark Millar). While Civil War tore the hero community apart ideologically, Secret Invasion aimed to destroy it from within through paranoia and mistrust. The creative team sought to evoke a sense of post-9/11 anxiety and the classic sci-fi paranoia of films like Invasion of the Body Snatchers. The central marketing tagline, “Who Do You Trust?”, became a cultural touchstone for comic fans during the event's publication, fueling intense speculation about which major characters had been secretly replaced by Skrull impostors.
The catalyst for the invasion differs drastically between the comic books and the cinematic universe, representing one of the most significant divergences in Marvel lore.
The Skrulls' plan for Earth was born from desperation, prophecy, and revenge. Their woes began when the cosmic entity Galactus, Devourer of Worlds, consumed the Skrull Throneworld, Tarnax IV. This cataclysmic event shattered their millennia-old empire, scattering the survivors across the galaxy and plunging them into a crisis of faith and identity. In this chaos, a new leader emerged: Princess Veranke of the Tyeranx 7 province. She rose to power by championing a radical interpretation of an ancient Skrull prophecy, which foretold that Earth was destined to become the new Skrull homeworld. Emperor Dorrek VII, viewing her as a dangerous zealot, exiled her. However, following the Throneworld's destruction, Veranke's prophecy became a rallying cry for the desperate Skrull masses, who elevated her to the rank of Queen. Their plan for conquest was deeply rooted in an earlier failure. Years prior, a group of Skrulls had attempted to impersonate the Fantastic Four, only to be hypnotized by Reed Richards into believing they were cows. This humiliation taught the Skrulls a harsh lesson: Earth's superhumans were too powerful to be conquered by conventional military force. A new strategy was needed. The opportunity arose from the actions of the illuminati, a secret cabal of Earth's most powerful heroes (Iron Man, Mister Fantastic, Doctor Strange, Black Bolt, Professor X, and Namor). After the Kree-Skrull War, they traveled to the Skrull Empire to issue a warning, but were captured and experimented upon. These experiments gave the Skrulls invaluable genetic data and, crucially, a deep understanding of their biology. Using this knowledge, combined with advanced technology and arcane magic, the Skrulls perfected their shape-shifting abilities, becoming completely undetectable by any known technological, telepathic, or mystical means. They could perfectly replicate not just a person's appearance and powers, but also their memories, thought patterns, and even their scent. With this new power, Queen Veranke initiated a long-term, systematic infiltration. Their strategy was brilliant and insidious: replace key figures within Earth's superhuman and political infrastructure. These sleeper agents would then act to sow discord, weaken defenses, and gather intelligence, paving the way for the final, overwhelming assault. One of Veranke's first and most crucial moves was to replace Spider-Woman (Jessica Drew), a hero with connections to S.H.I.E.L.D., Hydra, and the Avengers, granting her unparalleled access to Earth's intelligence and defense networks. The “Secret Invasion” had begun years before the first shot was ever fired.
The MCU's Secret Invasion presents a radically different narrative, re-contextualizing the Skrulls not as ancient galactic conquerors, but as a refugee species. First introduced in the 1990s-set film Captain Marvel, the Skrulls were victims of a genocidal war with the Kree Empire. A small faction led by Talos found an ally in Carol Danvers and Nick Fury, who promised to find them a new homeworld. For the next three decades, this promise went unfulfilled. While Fury and Captain Marvel were occupied with other galactic threats and the Blip, a generation of Skrulls was born and raised on Earth in secret, hidden within human society. A radicalized faction grew, led by a young, charismatic Skrull named Gravik. He felt betrayed and abandoned by Fury, believing that the only way to secure a future for his people was to take Earth for themselves. Unlike the comic version's religious crusade, the MCU invasion is a guerrilla war born from a broken promise and refugee desperation. Gravik's plan was not to replace heroes, but to destabilize human governments by orchestrating false-flag terrorist attacks and framing rival nations, pushing humanity toward a mutually-assured nuclear holocaust. His goal was to make Earth uninhabitable for humans, leaving it for the Skrulls, who are immune to radiation. Gravik established a secret settlement, New Skrullos, in an abandoned Russian nuclear facility and began augmenting his followers with a “Super-Skrull” program, using a machine to grant them the powers of various beings whose DNA had been collected over the years (the “Harvest”). This version of the invasion is less about cosmic scope and more about a tense, ground-level spy thriller, focusing on Fury's personal failures and his race against time to stop a conflict he inadvertently helped create.
The comic event can be broken down into three distinct phases: the long-term infiltration, the open invasion, and the political fallout that reshaped the Marvel Universe.
This phase spanned years, with Skrull agents subtly manipulating events.
The full-scale invasion was a coordinated, multi-front assault designed for maximum shock and awe.
The consequences were seismic. The public saw Tony Stark's technology fail and S.H.I.E.L.D. prove ineffective. In contrast, they saw Norman Osborn decisively end the threat. In a shocking political move, the President of the United States disbands S.H.I.E.L.D. and hands its authority and resources over to Osborn.
This new status quo, known as Dark Reign, plunged the Marvel Universe into an era where villains were in charge, and the true heroes were fugitives.
The MCU series follows a more contained, espionage-driven plot.
Gravik's faction operates in the shadows, executing a precise plan to incite a world war.
The resolution is more ambiguous than in the comics.

| Key Institutions | S.H.I.E.L.D. and S.W.O.R.D., both of which are compromised and ultimately fail. | The U.S. Government and MI6, both manipulated and infiltrated by the Skrulls. |
| Defining Moment | The combined forces making a last stand in Central Park. | Fury's one-on-one confrontation with Gravik, relying on wits and a final gambit with the Harvest. |
| Unlikely Ally | Norman Osborn and the Thunderbolts, whose involvement was purely opportunistic. | N/A. The conflict remains largely within the spy community. |
This is the single moment the “secret” war becomes an open one. The arrival of a spaceship full of “rescued” heroes, including some long-thought dead, creates immediate chaos. The subsequent reveal that one of the ship's occupants is a Skrull, followed swiftly by the crash-landed heroes themselves revealing their Skrull nature, and finally the betrayal by the Hank Pym Skrull, is a masterfully executed sequence of escalating paranoia and terror. It instantly validates every fear the heroes had been harboring and serves as the official declaration of war.
This phrase became the haunting signature of the Skrull infiltration. It was discovered that the Skrulls' final brainwashing technique involved forcing the captive original to accept the imposter, with the agent whispering “He loves you” or “She loves you” as a trigger phrase to unlock all of the host's memories and emotions. Its most chilling use was by the Skrull posing as Edwin Jarvis, the Avengers' loyal butler. When confronted, the Jarvis-Skrull's final words to Maria Hill before being shot were simply, “He loves you.” This implied a level of psychological violation that went far beyond mere physical replacement, showing the Skrulls were weaponizing love and trust itself.
The climax of the entire event is a brilliant subversion of superhero tropes. After an epic battle where heroes from every corner of the universe give their all, the final, decisive blow against the Skrull Queen is not struck by Captain America or Iron Man. It is delivered by Norman Osborn, the Green Goblin, who uses a StarkTech weapon to publicly execute Veranke. This moment is broadcast worldwide. For the average citizen, the story is simple: the heroes faltered, and a former villain saved the world. This single act of brutal pragmatism is what catapults Osborn to power and serves as the perfect, ironic conclusion to an invasion built on deception. The heroes win the battle, but lose the world to a monster of their own making.
