Though the Rangers are quickly accepting the reformed Karone as part of the Megaship crew, Dark Specter aims to make their happy bonding short lived. He sends a giant asteroid towards Earth, and will let it crash into the planet unless the former Astronema is returned to his evil side! The Rangers journey to the asteroid surface in an effort to destroy it through explosives, but encounter Quantron resistance. Karone takes a gamble of her own by returning to the Dark Fortress, but will this manuever backfire, when she finds her once loyal guardian Ecliptor has been reprogrammed by Darkonda? Meanwhile, Professor Phenomenus, Bulk & Skull spot the approaching space rock, but will anyone at NASADA believe them about it? (thetvdb.com)
