The World's Deadliest Game - S3.E6

The World's Deadliest Game: Brainiac uses a cloaking device to make the Earth appear to vanish. When Wonder Woman, Hawkman and Black Vulcan are in deep space trying to find it, the Toyman sends a phony distress message that leads them to his sinister black hole planet of toy traps. The Riddler then 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.
