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.
