Defenders of the Earth - Season 1 - Eps 52: Suspended Sabotage
While Rick and L.J. test out Rick's new invention- a wave interference device that scrambles any signal transmitted through the air- Rick is kidnapped by Ming, who then places an implant on L.J.'s head which will monitor his thought patterns. In exchange for Rick's safety, Ming orders L.J. to sabotage Flash's spaceship the night before our heroes plan to battle Ming's minions. During the fight our heroes are forced to retreat to Monitor. Ming then forces L.J. to divert the Defenders to South America while Ming invades New York City. L.J. recovers Rick's wave-interference device and rescues him. By the time the other heroes discover that L.J. is the saboteur, L.J. is able to explain himself and inform the Defenders of Ming's actual target. They arrive just in time to defeat the Merciless One.
