Stargate SG-1: The Fifth Race by i-defy-fate reviews
AU! Heavily inspired by the story: Project Blue Book by AmeliusTheAlteran. Elements of Halo will be here as well because I love the design of the ships, weapons and equipment they use.

Wrong Place, Right Time: A Hero's Story by DLTA-BOT reviews
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.

Halo: Universal Vortex by Legend of Flashfox reviews
With the rush of the firing of the rings errors occurred. More species come into play and humanity no longer started on Earth alone. The planet Elemental is here with humans who are different from Earth. Now Naruto needs to navigate this war torn galaxy. Alive preferably. Pairings maybe Harem. NarutoXHalo world merged with bits of others like Star Wars and Mass Effect. Maybe more.

On the Illusion of Might by evevee reviews
We thought ourselves powerful, able to conquer a galaxy with nothing but toys.

Wolves That Walk Alone (Hiatus) by TheManThatWalksTheAbyss115 reviews
There's always been growing legends in Remnant. Some of fearless warriors and others of horror, but there's one that's recently been picked up by the inhabitants. A legend of a man who was more akin to a wolf without a pack, barely speaking and doing his deed before leaving without a trace. After all... some people just want isolation rather than company.

Hyper-Lethal. There was but two Spartans with that designation. Each had seen worlds burn, armies fall and wars rage. This one will see a different kind of war, one in which stories sing the song of victory, not statistics.
