My Little Pony meets Rainbow Quest

The mane 6 defeated many foes. Sabre and the steves defeated many foes. They have defeated their different foes. This time though, they share the same foe. Can Sabre, the steves and the ponies work together to defeat or reform this new foe? Or will it be too late? The fate of not just MLP and RQ, but the fate of every reality lays in their hands, and hooves.
