A Halo 3: ODST crossover.

When Kix, a UNSC ODST with taste for shotguns and a quirky sense of humor, awakens on an unknown planet, he finds himself surrounded by colorful talking ponies. Unfortunately, they all seem to dislike him. "What's wrong with me? I'm a perfectly likable guy! But when you tie a guy up for no discernible reason and try to interrogate him, things get said and feelings get hurt! Even though I kinda attacked one of their royalty. And temporarily held one of them hostage." --Kix.

Stranded. That's what Starblazer was. Stranded in space while looking for the Manehattan, a ship that has mysteriously gone silent. But when her own ship, Celestia's Sun, breaks down in unknown space, all hope of rescue for both ships appears to be fading quickly. But when Ash, Starblazer's AI companion, receives a distress signal from the Manehattan, she rushes to save both them and herself. But is everything truly as it seems?
