Brainiac uses a cloaking device to make the Earth look like it disappeared and when Hawkman, Wonder Woman and Black Vulcan are in space trying to find it, Toyman sends a phony distress message that leads them to his sinister black hole planet of toy traps while The Riddler uses his super-riddles to lead the other Super Friends on a wild goose-chase that sends them to their doom. However, the efforts of Superman and Green Lantern foil their attempt and save Hawkman, Black Vulcan and Wonder Woman.
