The Kree-Skrull War is an ongoing thousand year conflict between the Kree and the Skrulls. The war started when the Skrulls had refused to submit to Kree ideologies, and thus were marked as fugitives. Following the destruction of Skrullos, the Skrulls became an endangered species on the brink of extinction, and were forced into refuge, constantly being hunted by the Accusers and the elite Kree operations unit Starforce.
The Kree are a major force in the galaxy that controls a vast empire. With their extremely advanced technologies and characteristic arrogance towards other races in the universe, they seek to force other civilizations in the galaxy to submit to the Kree rules, frequently waging wars against the ones who don't accept it. The Skrulls soon came to be one of the victims of these genocidal wars, sparking an ongoing conflict between the two races for over hundreds of years.
Destruction of Skrullos
At the peak of the conflict, the Kree destroyed the Skrulls' homeworld, Skrullos. This effectively turned the Skrulls into an endangered species at the brim of extinction, with the surviving Skrulls scattered around the universe, looking for a refuge.
During a test flight of the Light-Speed Engine piloted by Vers, they were shot down by Yon-Rogg. In the aftermath of the crash, Mar-Vell tried to destroy the engine so the Kree couldn't use it. But before she could, she was shot and killed by Yon-Rogg. Shortly after, Vers destroyed the engine, causing a massive explosion that gave her cosmic powers.
The Supreme Intelligence sent Starforce and Accusers to retrieve a Kree spy named Soh-Larr from Torfa, a planet that hosted a group of Skrull refugees. The Accusers bombarded the southern regions of the planet with Kree Ballistic Missiles, providing a diversion while the Starforce members silently infiltrated the planet, landed in its waters and used their suits to reach the surface. While Vers found what she believed to be Soh-Larr in a temple, the rest of Starforce was ambushed by a group of Skrulls disguising themselves as Torfans. While Starforce defeated the Skrull force with no casualties, "Soh-Larr" revealed himself to be Talos and abducted Vers.
Skrulls took Vers to their flagship in Earth's orbit, where they used a device to look through her memories for information regarding the Light-Speed Engine. As they were searching through her memories, Vers woke up, freed herself and fought her way to the ship's space pods. Talos damaged the space pod, causing it to crash-land on Earth.
Talos and three of the survivors from the Skrulls' Ship tracked down Vers to a Radio Shack store, where she was in a discussion with S.H.I.E.L.D. agent Nick Fury. One of them disguised himself as Phil Coulson, while another one attempted to shoot at Vers from a rooftop, but she spotted him and fired a photon blast at him, causing him to flee. Vers followed the fleeing Skrull to the 7th Street/Metro Center station where they both took a train, while the S.H.I.E.L.D. agents followed them in a car. Vers recognized the Skrull in disguise and started fighting him, but she was briefly restrained by the train's passengers, allowing the Skrull to escape from her, but not before he dropped a strange crystal which she picked up.
Vers attached the crystal that the assailant Skrull had dropped, to her uniform to extract its information, which led her to Pancho's Bar where she met with Nick Fury again and he agreed to help her find information about Wendy Lawson. The two headed to the Joint Dark Energy Mission Facility and found classified information regarding Lawson and, to their surprise, Vers' past as a pilot on Earth.
Fury, who had been instructed by the S.H.I.E.L.D. director R. Keller to capture Vers, used a pager to call them in, unaware that Keller was actually Talos in disguise. After 'Keller' and S.H.I.E.L.D. agents arrived, 'Keller' accidentally blew his disguise to Fury, leading to a fight between the two. Despite learning that Fury called the agents, Vers decided to save Fury. The two escaped the facility in a Quadjet.
After Captain Marvel, Nick Fury, Maria Rambeau, Talos, and Goose arrived at Mar-Vell's Laboratory, they were ambushed by Starforce, who sent Danvers to commune with the Supreme Intelligence, imprisoned the Skrull refugees and decided to dispose of Fury and Rambeau. But before they could, Danvers overpowered the Intelligence in a mental battle, managed to break free from it and the Photon Inhibitor, and asserted control over her full range of cosmic powers.
In the process, she caused the cells where the Kree were keeping the Skrull refugees to overload, giving them a chance to escape. Danvers retrieved the Tesseract and decided to give it to Fury. He refused to touch it but Goose swallowed it. Danvers then stalled Starforce, allowing Skrulls, Fury, Rambeau, and Goose to escape in a Quadjet. She fought and defeated all of her former teammates.
In a rage, Yon-Rogg authorized Ronan and the Accusers to dispatch Kree Ballistic Missiles at Earth. He and Minn-Erva then embarked on space pods to follow the Skrulls to Earth. Danvers damaged his pod, causing him to crash, and destroyed the incoming Ballistic Missiles. Ronan sent more forces to battle Danvers but she destroyed all of them along with one of the Accuser Warships accompanying him, forcing him to retreat.
On Earth, Minn-Erva tracked down the Quadjet carrying Skrulls, but Rambeau defeated her in air combat, destroying her pod and killing her. Danvers arrived on Earth and defeated Yon-Rogg once more, sending him back in his still functioning pod to Hala with a warning message to the Supreme Intelligence.
After their defeat at the hands of Captain Marvel when attacking Planet C-53, the Kree retreated from Earth. Danvers agreed to finish what Mar-Vell started and helped the Skrulls find a new home, using the Light-Speed Engine to travel to parts of the universe that were far away from the Kree. Before she left, she gave Fury an upgraded version of his pager, which enabled him to call for her assistance in emergencies from galaxies away. Goose later vomited the Tesseract, allowing S.H.I.E.L.D. to take it back for later use. The experience with the Skrulls and Kree showed Nick Fury that Earth was not capable of defending itself from alien threats and with Captain Marvel going with the Skrulls, he made a proposal draft originally called the Protectors Initiative but renamed it the Avengers Initiative after Carol Danvers' Air Force callsign.
