Dodekain #1

n epic but light-hearted take on the classic boy-and-giant robot scenario. After his homeworld is destroyed, an exiled alien scientist spends sixty years on Earth, preparing for the return of the alien armada. When they finally reach the planet, he is ready to launch his 15000-mile-high robot, Dodekain. But naturally, he is injured in the attack, and the only person available to run Dodekain is a teenage boy.
