Super Friends, Vol. 1

The Justice League, tipped off by The Wonder Twins, are looking for bombs hidden on Earth's continents by the alien villain Grax, with help from heroes from various countries. This issue, Wonder Woman teams up with The Olympian (of Greece), Aquaman with Little Mermaid (of Denmark), and Green Arrow with The Tasmanian Devil (of Australia). They find two more bombs, but one is still missing. Then they figure out that the last bomb is hidden on Earth's last continent- Antarctica! This last bomb is sensitive to body heat, so they recruit Icemaiden (from Norway) to dismantle it.

Meanwhile, Grax attacks the League's headquarters, but is defeated by Wendy, Marvin and Wonder Dog.

Afterwards, the young heroes announce that they are retiring so they can go to College, and the Wonder Twins are accepted as their replacements.
