(Re-writing this, so it's going down for a while until it's a thousand times better. Hope you all understand)
(Featured?! Wow! I never thought this story would make it to the feature box! Thank you everybody! :D)
Gamma-129 is a Spartan III of unparalleled ability and loyalty which none in his unit could surpass. His training; the hardest. His loyalty; the strongest. His squad; the bravest soldiers Gamma company has. Now Nathan and his squad face the toughest challenge yet; preventing the glassing and destruction of the UNSC's strongest military planet, Reach.

But, while trying to take out a Covenant Corvette from within, a slipspace malfunction sends Nathan and the enemy to the peaceful world of Equis. Weary of the strange alien in their land, the ponies of Equestria hold little trust for the super soldier. How can he convince his shaky ally's that he's the only one who can save them? It might only take the help of one lavender Unicorn to change that, and the Spartan's entire life.
