Earth-9930

In this reality, the planet Earth was invaded and conquered by members of a militant non-humanoid extraterrestrial race sometime in the first half of the twenty-first century. Little has been revealed about these aliens who were known to the humans as "Martians" only because they had staged their invasion from a base on Mars.^[1] During the ten years that these "Martians" ruled the planet, they slaughtered billions of humans, so that eventually there were only about fifty thousand humans left alive.^[2]

Early in the conquest or the occupation, six members of the Avengers were killed,^[3] their deaths witnessed by their comrade, the Black Panther, who then lead the team as they continued to fight against their alien overlords. During that ongoing struggle, new members joined the team, including an Ultron-created female synthezoid named Jocasta, a warrior-woman named Thundra from a divergent future, a Crimson Dynamo, a human mutate known as the Living Lightning and a skilled young fighter known as Killraven.^[1] It is not known what happened to Earth's other costumed super-beings or even if there were that many such beings (aside from the Avengers) on that alternate Earth.

About ten years after the conquest, when the territory controlled by the "Martians" was limited to New York City, the human fighting forces began Earth's last battle against the alien invaders. Although outnumbered by the humans, the aliens' Tripod-ships and their Skorpsmen ground warriors possessed devastating firepower and could have easily won the battle except for the arrival of two Avengers from the past, Giant-Man and a super-strong Captain America. Their participation caused the tide of battle to turn and inspired the humans to fight with renewed hope, and when the native Avengers joined the fight, the aliens fled. The Black Panther initially thought that the newcomers were his friends who had died so long ago, but once Captain America explained that they had come from decades in the past to investigate a temporal anomaly, he realized that they had gotten involved with the Destiny War.^[1]

When the battle against the invaders resumed, the human forces proved to be stronger than the aliens who retreated and attempted to reach Martian motherships in which they could flee the planet. When one such mothership began to lift off, the Avengers tried to stop it but were unable to reach it in time, and Earth's forces soon discovered that the Martians had mined the ships they had left behind so that they couldn't be used to follow them back to Mars.^[2]

Determined to follow the invaders back to Mars and destroy them once and for all so that they could never attack Earth again, the Black Panther led the Avengers and the two visitors to the ruins of his homeland, Wakanda, in order to obtain the Vibranium that would be needed to power the small fleet of spaceships he hoped to build. However, while investigating the Great Vibranium Mound, which the invaders had nearly mined out, the Avengers were attacked by small flying insectoid creatures with razor-sharp wings. When the battle attracted the mother of the creatures, a more-humanoid butterfly woman, she was able to communicate with Captain America. Once hostilities had ceased, she identified herself as Mourning Prey, an escapee from a Martian genetics lab, who had been led by a robed man to the mound where she could lay her eggs so that her children could be nurtured and sustained by the Vibranium. At that point, Jocasta, who had gone into labor during the battle, began to suffer complications when her unborn son started to shake violently, threatening the lives of both mother and child, and only Vibranium could ease the spasming enough to save their lives. With so little Vibranium left, T'Challa was forced to chose between using it for the spaceships that were needed to gain vengeance on the Martians or to save Mourning Prey's children, and Jocasta and her child. He chose life for the children over the death of his enemies.^[3]

After discussing with T'Challa how very convenient it was that situations had arisen in which the Vibranium needed for the space fleet was also required to save the lives of innocent children, Captain America and Giant-Man left that world in the Chronosphere that had brought them there.^[3]

Following the death and rebirth of the Multiverse, a shockwave of pure chronal collapse across a multitude of firmaments was registered by sensors in Avengers Tower in the God Quarry, prompting Avenger Prime to issue a Priority Omega alert. He then sent the army of Deathloks who were his agents out to gather reconnaissance reports from every charted universe and to deliver warnings to the local Avengers. One of those Deathloks set his course for Earth-9930.^[4]

Avengers (Earth-9930)

• On Earth-616, Kang the Conqueror once attempted to convince the world leaders to give him control of the planet so that he could protect it from the many threats that he had witnessed in various alternate futures, and showed them glimpses of those futures. One such glimpse was of an Earth being subjugated by an alien fleet staging from the planet Mars. Notably, that glimpse did not reveal that the Avengers had eventually driven the aliens from Earth.^[5]

• In order to keep humanity from spreading to the stars, Immortus tampered with this timeline in at least three ways:
  • He interacted with that militant alien race who had established a base on Mars and directed their attention towards Earth.^[6]
  • He may have subtly encouraged the romance between Jocasta and Machine Man, and possibly officiated at their wedding, so that she would become pregnant with a child who would require Vibranium in order to be delivered safely.^[3]
  • He found the wandering Mourning Prey and led her to the Great Vibranium Mound in Wakanda so that she could lay her eggs in a place where they would be safe and where her children could be nurtured and sustained by the Vibranium.^[3]

• The fact that the aged T'Challa knew about the Destiny War could be taken as evidence that this timeline was a possible future of the Earth-616 timeline from which five of the seven Avengers who participated in that war originated. After all, how else could he have learned of that war except from Avengers who had taken part in it? However, this idea has not been confirmed.
