Synopsis:
An electomagnetic accident in space causes Carthan, a warlord of the planet Dryanna, to become invulnerable to harm. Fearing Carthan’s popularity with the people, Xandor, the planet’s ruler, has the warlord exiled to Earth.

Upon finding that something in the constitution of his protective aura prevents him from seeking the direct aid of the Justice League, Carthan kidnaps Green Arrow, whom the super-heroes have just voted in as a new member. At the same time, he unleashes menaces controlled by a series of golden boxes, which had been created by Xandor to enforce his exile. He hopes that the Justice League will destroy the boxes, and indirectly free him.

Wonder Woman and Martian Manhunter battle giant insects created by the first box; Flash and Aquaman prevent the second box from causing Australia to sink into the ocean; Green Lantern destroys monstrous statues animated by the third box.

While Batman and Superman free the captive Green Arrow, the other members invade Carthan’s ship, only to become trapped in a gigantic hollow diamond. The archer rescues them by splitting it with a diamond-tipped arrow.

Carthan returns to Dryanna to settle accounts with Xandor, and Green Arrow becomes an official member of the Justice League of America.
