The Covenant has almost no males, and once they find a species whose population is half male, they begin a crusade for them. The UNSC will try to stop the horny horde, and save as many human pelvises as they can. And John 117 must personally make sure that those tiddied aliens fall. Smutty crackfic. From a prompt on /aco/.

Serin x Naomi I tried to make it make sense. It doesn't, not really. But they're gay! hehe.

An alt.-Halo story. (Timeline divergence after the end of Halo 3. Blending some of the plotlines from Halo's 4, 5, and Infinite into a single story, along with some of my own plot ideas as well. Tone and narrative style heavily inspired by Reach/CE. Borrows from the extended lore but not strictly adherent to it, significant changes have been made to many events and characters. WIP)

The Covenant had been on Talian for a good few months. They were doing what they could to survive, but everyone knew they didn't stand much of a chance. That is until an injured Spartan falls (literally) into the hands of a teenage girl who's somewhat versed in medicine and combat. Finally, the sun starts to rise over the fields of Blood and Ash.

AU. Noble team fell during the Battle of Reach. Its members giving their lives in the planets defense and to ensure that Cortana reached the Pillar of Autumn. Being equally responsible for the end of the Human-Covenant war and the survival of Mankind. Noble three, Jun-A266, was the only survivor of the fireteam. Well, at least that's how it originally was. Cover image is not mine.

This is same Halo story you all know and love… but different. Starting from Halo CE, this story was created to be Halo, but more badass. WARNING: this story is not appropriate for nerds.

Or 'How I became the bane of Humanity's enemies'. It just happened. I was there. It was ugly as hell, but now I'm helping as much as I can. Of course, things had to start in Harvest... but I'm not alone. (Halo Marine!Insert) (Some characters have been Genderbent, just a few)

This was the tale of how one team of Spartans survived the storm... And fought through the nightmares of the Covenant. Rated T for violence, death, and profanity.

After the night in New Mombassa came two weeks of Hell. Mission after mission, drop after drop. And then, right as they're about to rest, just as the Battle of Earth is won, Operation: BLIND FAITH is dropped on them. Alpha Nine will have to team up with new faces and journey beyond the portal at Voi, in search of weapons that could defend Earth. Daybreak s/AU

Months after the New Phoenix incident, the UNSC sends the Infinity on a second campaign to the Forerunner shield world: Requiem. UNSC forces and Spartan fireteams are sent in to repel vacant Covenant forces on the shield world and offer protection in exploring scientific discoveries. One such team in particular consists Fireteam Crimson. This is their story.

Following the end of Cortana's reign of terror, the ODSTs of Fireteam Wolf have retired and have chosen to strike out on their own in this big, uncertain galaxy. With their leader gone, Wolf must now discover for themselves what they want out of life.

With the war over spartan 005 had to sacrifice his own life to end the last remaining covenant fleet for him to be able to save earth from their last attempt at glassing the planet. S-005 thought he was gonna end up in the light but what he didn't know is that he had ended up in another world known to many as middle earth. With his new life at hand will the spartan start a new o

Following the loss of the Infinity, two Spartans join forces.

Spartan Serenity A. Steele, the UNSC's first Spartan-V prototype and a devoted combat medic, is mothballed to remote planets for colonial expansion. On Veridia, she's thrust into the midst of Cortana's uprising, triggering a millennia-spanning plot. Battling for the colonists' lives, Serenity grapples with her unexpected destiny, questioning her Spartan identity and humanity.

As Reach burned below, he made a fateful decision. Eternal glory would be bestowed upon the one who would conquer the human homeworld. But first, it must be found. Capturing the last Demon on Reach should have been a boon toward this objective. Instead, it becomes a great headache as his fleet stumbles upon the sacred ring itself. A twist on the original What if Noble Six survived.

Six thought he would die on Reach, but as it turns out, he's not the only one that's hard to kill. Kat is alive, and as the last two Spartans left to carry on the Noble legacy, Noble Six and Noble Two have to work their way off the planet or succumb to death on a doomed world. Can they escape the Covenant and get back to the UNSC or is their fate already sealed in blood?

Somehow, someway, she is here. The woman who died on that planet. We were told she was dead. But here she was. She turned to leave, but I grabbed her arm before she could. "Wait! Please stay." She turned to me with surprise, it turned into a simile that matched her face nicely. "Alright…I'll stay…"

A companion piece to HALO: Orion's Schism that expands on the battle of New Tampa seen in the story. This covers other parts of the battle previously unseen, and new perspectives in a series of shorter chapters.

Taken far out of her comfort zone and away from everything she's ever known, Senior Chief Petty Officer Kim has been assigned to Corbulo Academy for the past two years to assist in the training of UNSC cadets. But when everything goes wrong, when the Academy is attacked by a new unknown enemy, how far will Kim go to save those around her and those she's come to care for?

Enjoy!

When the UNSC mothership slips away without reason, Gillion is left stranded as the pilot and sole survivor of his Pelican crash. He is on an unknown planet, in an unknown ecosystem and worst of all; an Elite is stuck on the planet with him. Female Elite/Male Human.

Christian Oscar Rodriguez, once ensconced in 21st-century cybersecurity and a devotee of Halo, finds himself inexplicably catapulted into a human colony on the brink of the impending Human-Covenant War. Stripped of his former life and resources, how will he navigate a society paralyzed by dread? Can he uncover the purpose behind his sudden displacement? Even fate remains uncertain.

All Alex remembered was talking to her friend on Discord before waking up in a child's body and becoming a Spartan of the Orion II Project and was slowly forgetting her past. Virgil had no fucking idea why he woke up on a damn pelican but he didnt have time to fucking question it he was on the fucking run from ONI. A Halo/RvB mix.
