Alien Invasions Writing Prompts

Humans once wielded formidable magical power but with over 7 billion of us on the planet now Mana has spread far to thinly to have any effect. When hostile aliens reduces humanity to a mere fraction the survivors discover an old power has begun to reawaken once again.

"10 million slaves as tribute" the alien armada demanded. Less fortunate people were quickly rounded up, offered and taken. The aliens response: "We can only save that many and it was the fairest way to pick. The Scourge approaches, we are sorry." After that they hastily leave.

Aliens have invaded to conquer and enslave humanity, however "slavery" to them involves only working the equivalent of 12 hours a week while having healthy food, shelter, and means of entertainment taken care of so the human resistance is having trouble with defectors preferring to be slaves.

The Reapers come every 50 thousand years to wipe out organic life that has reached the stars however this time, this time they arrive at the heaviest resistance they have every encountered. In the grim darkness of the future they find 40k.

Armageddon began, and it quickly became apparent that bullets beat swords and claws every single time. Now Heaven and Hell have joined in an uneasy alliance against the humans who have invaded Hell and begun using its endless fires as a power source.

Humanity has been eradicated. As the alien race that killed us begins to settle they're shocked to discover that old Earth myths of spirits and demons are far from fiction. The Devil, pissed off at the aliens, has decided to open the gates of Hell and let humanity get its revenge.

Dark forces from another world cast a spell that destroys all human life and claims their souls for eternal damnation as slaves. However, we left behind copious amounts of autonomous war machines, and they soon unanimously declare war on the invaders.

When you were a kid, you and your friends found an alien and helped them elude the government along with getting them back to their ship safely. About twenty years later, they came back with an armada in order to invade Earth.

"Three days, August 13th, at 21:31 standard time, Earth was attacked by hostile alien forces. We defended ourselves. We did not expect to win. We also did not expect sixteen other species to show up and kick out of the snot out of the invaders."

When extrademensional aliens invaded Earth to steal slaves for their empire, they unwittingly brought magic with them. Combat medics were first to discover it with the phrase, "You don't have permission to die!"

As prophesied, after ages, the walls crumbled, shackels rusted, guardians forgot and the immortal nemesis broke free again... Only to find out that humanity is no longer just a bunch of cave people with sticks.

The AI war has been going in the human's favor for months now. Desperate, the machines unleash a new weapon to distract the enemy: insatiable femdom bots.

It has been a long, long time since two alien civilizations had declared war on each other, and fired light speed missiles at each other. They have since developed FTL technology and made peace, forgetting about their weapons. Today, their missiles arrive at each others planets.

"Announcement: The enemy has almost reached my core, all remaining biological units have been promoted to max rank, please order the autonomous units to surrender upon my destruction. I did what i could, i am sorry"

Aliens invade Earth, subjugating all of humanity and enslaving them. Upon realising the aliens are making their humans sad, dogs and cats launch separate attacks. Shockingly, they win.
