The races of Third Earth were unprepared for Mumm-Ras sudden assault, and even more unprepared for the turn it took. For Mumm-Ra had mastered not only technology, but necromancy as well! If theres any hope of survival, Lion-O, Cheetara, and Snarf must battle against the villainous Slithe and his zombie hordes for control of Thundera. Powerful artifacts will aid their battle, such as the Sword of Omens, the Claw Shield, Cheetaras signature Bo Staff, and Slithes custom Battleaxe. But, in the end, it will be their strength of will and fearsome resolve that sees them to victory!
