Voltron: Defender of the Universe

Lotor goes to the fume-covered Planet Medusa to arouse and take one of its sleeping inhabitants to fight for him. It turns out to be a monster who can attack with snakes as hair and turn things to stone. The Voltron Force are called away from trying to arrange homes for those orphaned by Zarkon's raid against Arus to fight it. Pidge is forced to eject his struck Green Lion, knocked unconscious, and taken underground by the beast. While the others wonder whether they'll see him again, he is horrified to recover near the creature, but finds the being, Anga, is kind to him. Haggar is determined to turn it evil so it will no longer side against its captors and with their enemy, while Lotor takes advantage of the divided protectors of Arus by sending another menace out. It is up to Pidge to see that no one falls under their power.
