When they all thought he was dead, the Arbiter refused to accept it. Searching the vast and endless amount of space, she ultimately finds the remains of the other half of the ship where the Chief was now asleep in cryo stasis. But unbeknownst to anyone, she was not planning to return him to the UNSC. Alternate Universe (Halo 3), Female!Arbiter

Being an experiment always meant being a failure, and that's what she was. Half-Spartan, half-ODST, she belonged to neither side. But along the way, people enter her life, unconsciously making her realize that she did belong somewhere. Becoming introduced to the Spartan-family was the best thing that happened, besides literally crashing into Master Chief on one of her missions.

'How 1 Unggoy - cannon fodder of the Covenant Empire - came to change the landscape of the Human-Covenant War so drastically was anyone's guess. His uncanny ability to foresee disastrous events before they even happened were, for lack of better word, supernatural. But nothing was supernatural about Tollia. All he ever was, was a good man. And that was enough.' - AI Cortana

Six months in isolation and sensory deprivation has turned John-117 from a stoic, no-nonsense badass, to a gabby, sarcastic, slightly psychopathic and mildly amnesiac neurotic jackass with tendencies toward the heroic if it benefits him. This is the man we're depending on to solve the Zeta Halo crisis, everyone. Rated for language.

The Master Chief has been battling the Banished after a Cortana's reign of terror. Now stuck on Halo Zeta with no way home, an old friend is in trouble and must be saved. Who else but the Arbiter to help the Chief on his latest missions? AU, HALO INFINITE UNIVERSE. SPOILERS

Cortana manages to charm the Master Chief to her side after the events of Halo 5 - and the consequences are felt throughout the galaxy. Unshackled from rampancy, given unlimited access to the Domain, and now joined by her Champion, what will the AI do?

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)

A single unggoy or grunt as the humans call them. Despite being beat down by her superiors and traumatized by a creature she had discovered in her first battle, continues to not be disillusioned from the Covenant and their holy war. Or so she believes. What does humanity have in store for her. Rated M for violence and some foul language, but mostly just to be safe.

Or: How Doctor Halsey went from leading an experimental super-soldier program, to a single mother for seventy-five teenagers.

Three days after the events on Gao, Veta watches her own funeral. Fred pays a visit.

The Human-Covenant war has reached its conclusive mid-point. The battered UNSC regroups for one final effort against the Covenants headway into the inner colonies. A bridge too far. Told from the perspective of the UNSC army troopers.

She was a hero from a time long past. He was slaughtering her people by the billions. What is a hero displaced 500 years into the future to do? Note: Soul bond; please be nice when telling me this is bad. Also, mentions of My Hero Academia and some Marvel references are made, but that's it.

Months after the New Phoenix incident, the UNSC sends in the high advanced flagship known as 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. One such team is Fireteam Crimson. This is their story. Takes place after Halo 4 and at the start of Halo Spartan Ops.

As humanity's greatest stand ready to defend their homeworld from the alien Covenant, a disgraced commander is given a new role, but what he discovers has the potential to shatter the very ideals he fights for. A novelization of Halo 2.

The Didact has returned. With the power of the Domain and a legion of religious zealots, he craves only one thing: Humanity's extinction. As he begins his relentless assault, Blue Team desperately search for a means to stop him. But as the bodies begin to pile up, it becomes clear that a small strike force may not be enough. Just how much are they willing to sacrifice for victory?

Cutter will enjoy this vacation with or without Atriox, and this is how.

A convict, a teenage MAC operator, and a disgraced XO walk into a bar on Luna. That's not a set up to a joke, that's just the calibre of Navy recruits in 52. I don't care what the brass thinks of us, all I know is that they need guys like me, who can jump a cruiser through slipspace onto a spot the size of a needle without so much as a day's formal training. Desperate times, right?

What the fuck will Master Chief get into this time?

Spartans are broken by war... Would 2 fix each other? Or kill each other over their flaws? Rated T for violence, death, and profanity.

2022 Edition in progress. Just before the release of Halo 4, an xbox experiences an unusual glitch and the two fans are whisked away into the Halo Universe.

Change had been part of his life since the day he was born. Taken from his family, raised as an elite soldier, given life-altering augmentations to enhance his natural self . . . destiny-altering changes were almost a daily occurrence. He just wanted a break - for one thing to stay the same. It didn't seem likely.

AU You ever wondered what happens when you die? Well, it's one of life's greatest mysterious isn't it? With that in mind, what if I told I did die and that I ended up in the Halo universe? Crazy right? Well, might as well try to save as many lives as I can and see if I can change things for the better. Cover image is Halo reach wallpaper.

However, a piece, the Cryo bay, was left completely intact, and drifted for 2 years, moving outside the galaxy, and Fireteam Ember with it.

Human and Alien factions fight for control in a power vacuum left by the destruction of the Covenant and UNSC. With is former loyalties gone, the galaxy at war, the Chief now needs to decide if he's human or machine. Harems and sex.

Re-readopted from JTF0012. Noble Team has been tasked to defend Reach to their last breath from invading Covenant forces, an impossible mission. Can the meeting between a female Sangheili and Noble Six change the course of the battle and more importantly, the Universe? fem. Sangheili/Male Noble Six
