The Skrulls have conquered or colonized every suitable world in the Andromeda galaxy. Tens of millions of years ago they were already expanding into neighboring galaxies becoming an intergalactic empire. In the modern era, the Skrulls control worlds throughout the Andromeda galaxy and in neighboring galaxies. A thousand races were conquered and absorbed into the Skrull Empire. It's an empire with likely trillions of sentient beings. The Skrull capital was relocated to Tarnax IV from Skrullos a 100,000 years ago.
Aided by their shape-shifting powers, the Skrulls departed their homeworld into space. When they encountered a new race, they simply transformed themselves to resemble that race. The empire that resulted from these contacts was based on free trade and mutual cooperation . In the beginning the Skrulls were a peaceful, scientifically inclined race. Their scientists also formed the first Cosmic Cube that later became the Shaper of Worlds.
The Skrulls voyaged to the Milky Way and Large Magellanic Cloud. In the latter cluster they discovered the Kree homeworld of Hala. The Kree were in the dawn of their culture; at this point they shared Hala with the plant race, the Cotati. The Skrulls decided to favor one of the races with their advanced technology and devised a test to determine which would be the favored race.
The Skrulls created the Blue Area of the Moon and transported bands of Kree and Cotati there. Both groups were left to accomplish what they could. The Skrulls judged the Cotati’s works to be superior. This angered the Kree and led to a vicious attack in which the Kree band slew the Skrull judges and the Cotati. The Kree stole the Skrull's star-ship and technology. Because of the immense distances involved, decades passed before the Skrulls learned of the Kree's activities. By this time it was too late. The Kree had become advanced and audacious enough to attack the Skrulls in their home galaxy. During the millennia that followed, the Skrulls developed the vicious streak needed to conduct intergalactic war. Their entire culture was remade in the warrior image as the war began.
EarthSkrulls became aware of Earth when they discovered a space warp linking Earth and Throneworld. Later they discovered that the Earth possessed an equidistant link to Hala. They saw Earth as a world to conquer but they were content to hold off a full invasion, perhaps afraid the Kree would learn of the plot. Because of their caution, the Skrulls sent only a handful of scout warriors to infiltrate Earth.
Fearing the Fantastic Four would stand in their way of an invasion of Earth, four Skrull agents came to Earth and posed as the team in order to ruin their reputation. The real Fantastic Four were able to expose the Skrull agents and clear their names. The Fantastic Four stole the Skrulls' rocket ship and found their mother-ship in Earth orbit. Posing as the Skrull agents, they tricked the captain into believing that Earth was too dangerous to invade. Reed Richards "volunteered" to stay behind and remove any trace of the Skrulls' presence on Earth. Falling for Richard's deception, the captain called off the invasion. Once back on Earth the Fantastic Four hid the remaining Skrull agents by convincing them to transform into cows. Reed hypnotized them into believing they were real cows. They were left in a field to graze for the rest of their lives.
Fall of an Empire
The Skrull throneworld was devoured by Galactus and the Imperial starfleet destroyed by Galactus's herald, Nova (Frankie Raye). With the destruction of a central government, the Skrull Empire collapsed into hundreds of bickering factions. Their galaxy was now filled with Governors declaring themselves “Emperor." The Shi'ar maintained a heavy presence in the former empire as well, constantly dealing with pockets of resistance.
The greatest blow to the Skrulls was the destruction of their shape-shifting powers for a time due to their Hyper-Wave Bomb which stabilized the deviant genetic code of all Skrulls everywhere that granted their abilities. This was accomplished by Reed Richards and yet another Governor-turned-Emperor. The Skrull warlord Kylor restarted the war with the Kree upon the visit of a Celestial to his world and learning that the Kree had discovered that the Skrulls had lost their shapeshifting abilities. The Skrull warlord S'Byll and the Super-Skrull manipulated the Silver Surfer into fighting on the side of the Skrulls against the Kree and their Badoon allies. Using Skrull science they transferred some of the Silver Surfer's Power Cosmic to S'Byll, mutating her and giving her the ability to restore the Skrulls' natural abilities via touch. Upon the conclusion of the war that ended in a truce, S'Byll who was now Empress moved the throneworld to her homeworld, Satriani.
Annihilation Wave and Secret Invasion
The Skrull Empire was the first of the major interstellar empires to be invaded by the forces of Annihilus. Within less than six months, what little remained of the Skrull Empire was destroyed. The Annihilation Wave's super weapon, the Harvester of Sorrow, destroyed hundreds of Skrull planets. In the aftermath the Skrulls unsuccessfully attempted to convince Hulkling to become their new Emperor.
With almost all their planets destroyed and under the leadership of the extremist Queen Veranke, the Skrulls infiltrated Earth for a major assault. Several heroes were replaced by Skrulls. Eventually, Reed Richards was able to pierce through the shape-shifting and all heroes and villains banded together to stop the Skrulls. Unfortunately, the Skrulls activated a fail-safe within the Wasp, turning her into a biological weapon. Thor had no choice but to "destroy" her. Angered, the humans attacked the Skrulls, killing Veranke and destroying their fleet in orbit in retaliation. All the missing heroes, villains and S.H.I.E.L.D. agents were found alive and returned to Earth.
The Super-Skrull became one of many Warlords seeking to re-unite the divided Skrull territories, eventually growing in power and influence until he became one of the six most powerful Warlords. During the invasion of the various interstellar empires in the Local Group of galaxies by the mysterious Builders, the Skrull Warlords united against this common foe. When news of a War Council of various galactic powers reached the Skrulls, Kl'rt was chosen to represent the Skrulls. An alliance was created, with Kl'rt commanding the Skrulls and playing a key role in the council.
The war initially went poorly, but the alliance eventually managed to turn the tide and through a series of key battles, the Builders were defeated and the worlds occupied by them liberated. In order to repay the efforts of the Avengers in the war, and seeking glory and great battle, Kl'rt accompanied Alliance forces to Earth in order to free it from occupation by Thanos. They succeeded in liberating The Peak and killing one of Thanos' lieutenants, Black Dwarf. After his great victory in the war against the Builders, Kl'rt was crowned Emperor of a reborn Skrull Empire, as the alien race now settled on the planet Tarnax II.
