Secret Of The Sinister Sorcerers When all man-made objects on Earth stop working, the Justice League band together to try and figure out the cause of this latest crisis and soon learn that magic has become the dominant force in their universe. Meanwhile in the other worldly dimension known as Magic-Land, the evil magician Simon Magnus has used his magic to transport items of science to that realm to try and over throw it's ruler and his great magician Merlin.
While back in the Earth dimension, the JLA realize that magic spells now work, and so they get a number of books on sorcery to summon Merlin to aid them. When they realize what has happened, Merlin uses his now restored magical powers to transport the Justice League members to the realm of Magic while Snapper and Merlin stay behind on Earth.
The Justice League pair off into groups to stop Magnus and his two cohorts, using their super powers and cunning to get past all their traps and easily destroy whichever scientific device they are using as defense. Afterwards, they capture Magnus and demand that he return to their world and restore everything to normal. However, when traveling to the gate between worlds they have to fight a giant, but with the help of Snapper and Merlin the giant is defeated. Returning to Earth, Merlin is able to reverse the damage done by Magnus and he bids the Justice League farewell.
