I have recently re-watched star Trek ds9 and had a thought of how the story change if instead of the federation, it was the unsc.

Through unknown forces of immense and unimaginable power, two galaxies merge and superpowers of both galaxies is forced to deal with the reality of the broken status quo. Jane Shepard, first human Spectre, finds herself in the center of the events to come. This is a 3-way crossover between the forementioned ME and Halo universes as well as Stargate. Knowledge of all are not needed.

The Master Chief is found by the Atlantis Expedition, how did the Master Chief end up in the early 21st Century and in the Pegasus Galaxy?

After the Human-Covenant War, at a reterraformed Reach, a mysterious ship arrives: unknown design, unknown insignia, unknown how he ended up at Reach Note 1: mild violence and a few less liked words: e.g. "hell" Note 2: The crossover may take awhile... due to me wanting Noble Six(Male, 22) and Sergeant Major Avery Johnson alive Note 3: Enjoy, please do be civil with your critiquing

The Beginning of a new Era for the Milky Way Galaxy, with the assistance of the Forerunners and new allies along the way, the Rose Empire will stand tall above all and build a Empire for Peace and Justice to flourish.

It had been ten years since Noble Six joined the NYPD, following the fall of Reach, quickly moving through the ranks and making detective, but when he is transferred to the 99th precinct, he finds his life flipped upside down when he has to work alongside the eccentric squad of the Nine-Nine. If his past doesn't drive him insane...they certainly will!

The Lonewolf survived and made it off Reach .Now he finds himself trapped in another world, another time and another conflict. Up against a madman forcing a race of super powered aliens to fight to the death to bring a new age of the gods . (Six and Harem)

The SPARTAN and those that join will fight to Reclaim the world...

The journey of a hero doesn't always start where they expect. It doesn't always happen to those who expect it. Damon was never interested in being what SPARTANs represent: an implacable force for good standing as humanity's shield. Like most other third-generation SPARTANs, the war took everything from him. All he wanted was to return the favor. Sometimes we don't get a choice.

For what is a child if not innocent, and what is a man if not sinful? A vessel of hate, unbridled and pure. And we are the best of teachers to our child.

What if Master Chief and Cortana had a child. What if that child was named Jane Shepard. What if the UNSC and Turians didn't have a hostile first-contact. Pre first-contact to (hopefully) post Me-3. Pray for me ya'll this one's ambitious.

The year is 2583. Humanity stands strong, even twenty-six years after a disastrous first contact. But it seems that wherever they go, war will follow. And this war will grip the galaxy like no other. The first adventure of Mass Effect: The Reclaimer Saga. Rated M for graphic depictions of violence.

Master Chief finds something in a strange world full of even strange new enemies called the Grimm. To make his adventure even more bizarre, he meets four teenage girls. One who won't stop fangirling.
