When the Time-Twisters seek to destroy Earth, Thor embarks on an adventure with Zarrko the Tomorrow Man. It's a battle through time (with dinosaurs!) that will impress you to the end! Then, Thor fights the Firelord in the jungles of Latin America — and only Jane Foster can save him! The Warriors Three ramble off on a solo adventure, while Thor returns to Asgard to face the one and only Mangog! Their battle will rage across the Fabled Realm, taking Thor to Hel in a quest to save Odin! Plus: the return of "Tales of Asgard," Thor vs. Ulik the Troll and a giant-sized epic featuring Hercules!
