Call me Shiro. My story begins when I find myself in the land of Equestria. I would say something cliché, like, “a world I only thought existed in a show for little girls” or something, but it really isn't. I mean, sure, it's similar enough, but at the same time it isn't the perfect, peaceful world they depict. For starters, I haven't met a pony who hasn't had somepony the know and love get eaten by some predator. That's where I come in.

You see, when I arrived, I was changed into not a pony, but a tiger. I don't care what you say, I'm not a Gary Stu! Sure, I have chaos magic, get a girlfriend in less than a month, and get a katana, but the katana breaks... while fighting an elder god... Okay, fine, but I don't go full Stu. You never go full Stu. Anyway, this is the story about my quest to protect these ponies that I came to love.

Chaotic Harmony is an over-the-top action/comedy (emphasis on comedy) that takes all the clichés you know and love (or hate) and breaks, twists, turns them on their ears, or pumps them full of adrenalin and laughs as they rape your brain. This is, however, also a story about overcoming loss and forging a new life.

Contains: Different-but-not-quite-different-enough-for-AU Equestria, ridiculous comedy, over-the-top DBZ level action, borderline Stu self-insert, tigerxpony shipping, and dark, emotional chapters later on.

You'll laugh, cry, cheer, and d’aww throughout the rollercoaster ride that is Chaotic Harmony.

SGT Jennings dropped into New Mombasa to take over a Covenant cruiser. When a lucky Anti-Aircraft shot takes away his ability to control his pod, he careens end-over-end into a slipspace portal, and emerges in Equestria.

Be warned, there is more cursing in the beginning then there will be later, due to an all-military environment in the beginning.

An undead Emperor in need of a new body. A Spartan lost in space. A ragtag team on a suicide mission. What do they all have in common? They all wind up on the magical world of Equestria, where war has been forgotten. That, however, is soon about to change.

Three heroes ripped from their own reality to be imprisoned in... Equestria? Follow Edel, Lorane, and Regal on their journey on their epic adventure as they explore this strange land called Equestria, discover what i's like to live like a pony, and try to find a way back home before it's too late...

As the story goes, the prologue will be more explained, so Don't worry too much! It only becomes more and more surreal as the main heroes discover the peaceful atmosphere of Equestria as opposed to the violent nature of their home, which has in turn caused them to be mistrusting of others and always expecting a fight from other creatures, pony or not. As they live in Equestria, they learn some ponies can be trusted, and others still not.
