The races of Third Earth were unprepared for Mumm-Ra’s sudden assault, and even more unprepared for the turn it took. For Mumm-Ra had mastered not only technology, but necromancy as well! If there’s any hope of survival, Tygra, Panthro, Wilykit and Wilykat must battle against the villainous Jackalman and his zombie hordes for control of Thundera. Powerful artifacts will aid their battle, such as the Tygra’s Bolo Whip, Panthro’s Nunchaku, and Kit’s and Kat’s clever bombs and chemical capsules. But, in the end, it will be their strength of will and fearsome resolve that sees them to victory!
