Earth-804 would diverge from Earth-616 at a crucial point during the Kree-Skrull War. In this reality, when Rick Jones would attempt to harm his captor Ronan the Accuser, Ronan would slay the boy for his impudence.
As the Avengers would fight their way through the Skrulls and learn their comrades Scarlet Witch, Quicksilver and Captain Marvel were prisoners of Dorrek VII, the Supreme Intelligence would attempt to access the Destiny Force through Rick Jone's dead body, but fail.
As the Avengers would battle through the Skrulls, the Vision would go on a rampage, demanding that his love be freed. The Avengers would learn that the Skrulls had launched a nuclear warhead toward the Earth, and would dispatch their teammate Goliath to stop it. While on the Skrull home world Anelle would attempt to get her father to stop hostilities, he would strike her, prompting the woman to work against her father. At that time, Captain Marvel had finished the Omni-Wave Projector and attempted to use it to contact Rick Jones. Learning that Jones was dead, he would become furious and go on a rampage through the Skrull palace. This would prompt Dorrek to release the Super Skrull and order him to take down Mar-Vell. At that same time, Goliath would destroy the Skrull ship carrying the nuclear warhead and head back toward Earth. There he would be shocked to see a massive Kree armada preparing to attack his home planet.
Detecting the invasion fleet, Mr. Fantastic and Professor X would begin gathering heroes and villains from across the globe to help fight off the Kree invasion. Goliath meanwhile would board the SHIELD Helicarrier and convince Nick Fury to be the first line of defense against the invaders. While the SHIELD Helicarrier was the first to confront the Kree warriors, it would prove to be no match for the Kree's superior firepower.
As the war would rage on, Iron Man would be seriously wounded in battle, prompting Thor to bring him to Asgard for healing and to convince his fellow Asgardians to join the war effort. As the Earth heroes would battle on in space, Captain America and Vision would go to the Skrull homeworld to rescue their friends. While inside, Quicksilver and Scarlet Witch would be found by Anelle who would suggest a truce, and Captain Marvel would slay the Super-Skrull.
The Supreme Intelligence would at that moment merge with Rick Jone's body, rebirthing itself into a new more powerful being. It would slay Ronan and then order the Kree fleets to stand down. At that same moment, Dorrek would be slain when his laser cannon would be blasted by one of the Scarlet Witch's hex bolts. With Dorrek dead, Anelle would succeed the throne and order the Skrulls to stand down. With the battle over, the Earth heroes would return home where the Avengers would mourn the loss of their friend Rick Jones. While in space, the Supreme Intelligence would confront Mar-Vell and tell him that it was leaving to discover itself and would leave Mar-Vell in charge of the Kree empire and to forge everlasting peace with the Skrulls.
