Trial of the Super Friends - S3.E10

Batman, Robin, Wonder Woman and Green Lantern guard the liquid light in the Astro-Chemical Research Plant. However, the Cheetah secretly steals Wonder Woman's Lasso of Truth, Brainiac steals Green Lantern's power ring and the Scarecrow steals Batman and Robin's utility belts. The three villains escape, and the Hall of Doom captures and puts the four heroes on a kangaroo court trial. Sinestro uses the power devices stolen by the three villains as evidence to prove the Super Friends are guilty. Brainiac punishes them by making them fight his android duplicates of them, and the captured Super Friends must save themselves from their own devices before it is too late.
