Scooby-Doo and the Alien Invaders

In a bizarre occurrence that seems to be out of this world, the Mystery Inc. gang finds themselves face to face with an intergalactic invasion on the sleepy coastal town of Atlantic City. The town is abuzz with rumors of alien sightings and encounters with flying saucers. At a local museum, they stumble upon a mysterious exhibit of alien artifacts and a holographic message from a being claiming to be from the planet Zorgon. Fred, Daphne, Velma, Shaggy, and Scooby arrive at the town, only to discover that they have been recruited by the Air Force to assist in uncovering the truth behind the alien invasions. With the help of their new Air Force friend Sergeant Casey, they begin their investigation. Velma soon discovers a series of strange symbols etched into the walls of the museum's exhibits, leading her to speculate that these symbols may hold the key to understanding the mysterious events unfolding in the town. As they delve deeper into the mystery, they soon encounter a mysterious beauty named Ruby Doodle, who appears to be an alien herself but claims to be the daughter of a famous astrologer. Ruby reveals that she has been sent to the Earth to gather information about a planet called Zorgon, a planet said to be under attack. Ruby's story seems to be authentic, but the gang cannot help but wonder if she is hiding something. Meanwhile, Shaggy and Scooby stumble upon a suspicious looking spaceship and get lost inside. There, they accidentally stumble upon an alien laboratory where they discover various human-looking aliens disguised as humans, leading them to suspect that these individuals are the ones responsible for the alien sightings. Back at the museum, Velma has made some breakthroughs about the symbols, realizing that they are part of a Zorgon language. She soon deciphers the message that the symbols hold and discovers a shocking truth about Ruby. The mystery deepens as the gang discovers more clues pointing towards Ruby's involvement in the Zorgon invasion. As the investigation unfolds, the gang discovers that the supposed aliens are nothing more than a cover-up for a nefarious organization planning to steal the world's most valuable treasures. Ruby is revealed to be an alien, but not one from Zorgon - rather, she is an alien from a nearby planet trying to prevent the Zorgon's attack on Earth. She is on the side of the people and had actually been working to help the Mystery Inc. gang. However, the gang soon realizes that a member of the Mystery Inc. crew has been playing both sides all along. The traitor reveals that it's Ruby's ally - none other than the Air Force's own Sergeant Casey. The Zorgons, with their advanced technology, planned to launch a fake rescue mission on Earth as part of their plan to conquer the Earth. It's up to the gang and their new alien friend Ruby to save the day by stopping the would-be traitor and the true alien invaders. They concoct a plan to expose Sergeant Casey, disable his communications, and prevent the Zorgon invasion. As they execute their plan, Fred, Daphne, Velma, Shaggy, Scooby and Ruby make it to the control room of the supposed rescue mission just in time. The Zorgon leader is attempting to take control of the town communication system, and Ruby helps the gang take down the traitor. They also disable the communications equipment, and the Zorgons fail to contact Earth, thus preventing the invasion. As the town breathes a sigh of relief, the Mystery Inc. gang reflects on their adventure and the mysteries that still surround the universe. With the Zorgons' attack thwarted, the gang and Ruby Doodle, their new friend, are honored for their heroism and continue their journey with their intergalactic ally.
