A Slipspace experiment gone wrong leaves the United Nations with the means to create a peace-keeping army. Now, as the Triwizard Tournament is hosted at Hogwarts, Harry Potter's biggest secret emerges... He is SPARTAN-B147 of the United Nations Space Corps BETA Squad...(There will be Master Chief and Doctor Who references aplenty...OC spots available by PM!)

When Eragon alters Slipspace it brings the UNSC and the Neo-Covenant to a whole new world where magic exists, and the land looks like it came straight from a fairy-tale... The rules have changed, the board has been flipped, and dimensions have collided... And the fic has been dropped. Feel free to crap on it via reviews.

The SPARTAN-IIs. Trained child soldiers. At the age of fourteen they underwent augmentation procedures. Afterwards the ones that survived underwent even tougher training, and in an effort to make sure they could wage war. 14-year old Spartan Trainees John-117(The Master Chief), Kelly-087, Fredric-104, and Linda-058 are pulled straight into a strange new world. [Discontinued]

Takes place 20 years after the first story. War drums are starting to sound once again and soon, the final battle to detremine the fate of Adromeda shall begin.

El Covenant se prepara para una invasión contra la Infinity, pero termina combatiendo contra otras fuerzas, ¿Qué futuro le deparará?, Nuevas amistades y alianzas se formarán, una verdad será descubierta y un universo será salvado. Un viaje le deparará a esa nueva alianza

A spin off of Autobot on Titan, sorta. This takes place before AOE. Roadbuster and his new found partner Nautica are taken into the future during a space bridge accident. There, they encounter a new world called Requiem, and a man that goes by the name, John-117 and his A.I, Cortana. Now they must work together to survive the coming trials that Requiem can offer.

Harry isn't just mean't to defeat Voldemort, a Month Before the Second book, He Comes across Dudley watching Halo 4 Terminals, and he feels a familier chill to it, It is Time for the Return of The Lord of Admirals.

Ancient species from 7 universes converse about a common problem. Epilogue to my first short story, "The Mantle," read that first. Crossover between Halo, Metroid, Mass Effect, Dead Space and more. Rated T

Fresh from the war against the Reapers, the Master Chief, Cortana, Teana, and Commander Shepard investigate rumors of activity from the Covenant terrorist faction led by the anti-human Sangheili kaidon Jul Mdama. Following the intel, the quartet stumbles upon a Forerunner artificial world with an ancient secret buried within. But some secrets are better left buried...

Fate is inevitable, it is determined by the variables that make up the equation that leads to it. However a new variable can greatly change the path, and an ODST is a powerful variable.

Instead of humans and the rest of the mass effect galaxy being improbably isolated for hundreds -if not thousands- of years humanity and the Covenant is instead placed in a totally separate galaxy.

What would happen if the artifact that was brought on board the Infinity could do more than materialize people down to Requiem? What if it could bring in people from another dimension? One where the UNSC is unheard of and the Third Reich rules with an iron fist? Join Kurt Meyer, a rouge Spec Ops Reich soldier as he interacts with the Infinity and the Halo Universe.

Another idea that came to my head. Warning T for my foul language.

Ten years have passed since the Human-Covenant War ended and the birth of the Species Assembly has brought peace to the Galaxy. Or, at least their part of it. The discovery of a Mass Relay sparks yet another war that will have consequences for all sides involved. The Galaxy will never be the same. Disclaimer: I do not own the franchises.

After a horrible drop. Private Connor 'Ranger' Rodgers finds himself in a land that is quite different than what he used too. but he will try his hardest to fight for a way back home. "WHY THE HELL IS THERE A DRAGON! AND WHY DID IT CALL ME DOVAHKIIN!"

Every choice we make creates 2 universes, one where we made the choice and another where we didn't. Billions of people, making Billions of choices, makes infinite universes, and infinite possibilities. This is one of them.

Humanity is at a Golden Age of society, with all bigotry and racism removed and scientific marvels are steadily discovered and recovered from the past. All three sects of man have been found and joined after the seeds were spread across the stars by the Forerunners. However and new threat arrives to threaten the peace. AU. Rated M for all the right reasons.

It's 2556, and the Master Chief is about to get a nasty surprise. Meanwhile, 543 years in the past, UNIT are about to get backup, and the Zygons are going to wish wormholes in the fabric of space-time didn't exist. (ON EXTENDED HIATUS)

In the year 2031, the first interstellar fleet leaves the moon and is never seen again. The cause: an undetected error in the jump drives. Now without a planet to call home, the fleet is thrown into two separate wars, with the fate of both lying on their shoulders.

(Looking for an Artist to draw Blake for Cover!) Blake-027, Assassin, Spartan-II, Soldier. Blake is many things, and isn't surprised by much, but what happens when a back OP goes from fubar to "WHAT THE HELL?" in a matter of minutes? Well, your guess is as good as mine. (Note, M for a damned reason.)

During the battle on the planet Korthal, an ONI agent was suddenly sent to a universe where devils exist and supernatural incidents are an everyday norm and worst of all, meeting his perverted parallel counter-part which looks like him but shares nothing like poor ONI operative Ichiko Uni. [I DON'T OWN HALO OR HSDXD]. (I am a new writer so go easy on me) I
