Long time ago, back before the Two Pony Princesses recovered the Elements of Harmony... there was a titanic battle between a Majin and a Spirit of Chaos, inevitably the Majin won and as a prize she consumed the spirit and was trapped in stone by the Princesses when they unleashed the Elements of Harmony.
Now, over a thousand years later, The Majin Destroyer is back and ready to kick some flank!
