Meanwhile, supervillain Dick Dastardly attempts to steal it's vast treasure and rescue his canine henchdog Muttley from the Underworld.

Synopsis
At Venice Beach, California, an unmanned, stray puppy is wandering the streets looking for food. He comes across a restaurant, Alexander's Great Gyros, and sees a giant piece of meat hanging in the window. Seeing as how the meat was unclaimed, the puppy thinks nothing of picking it up and stealing it.

The shop owner calls out as his meat is being stolen and a cop starts pursuing the puppy. In the midst of the pursuit, the puppy bumps into a young boy, Shaggy Rogers, who is walking by himself to the beach. However, the puppy keeps on running away from the cop, paying little regard to Shaggy.

Shaggy plugs in earbuds and begins listening to music on his phone. The song he is listening to is about loneliness, so he changes the music station. The next song is also about loneliness, so he changes the music station again. This continues on for a few songs until he gives up and begins listening to a podcast, only to find out that it is about loneliness.

After a long chase, the puppy eventually escapes the cop by hiding behind two mounds of sand. Shaggy then comes up to the mounds of sand, unaware of the puppy's presence, and sets up a picnic, pretending that the mounds of sand were his friends.

The puppy overhears and starts to feel empathetic towards Shaggy and comes out from behind the sand, offering to eat with Shaggy. When Shaggy explains that while he has a sandwich to share but that it doesn't contain any meat, the puppy brings out the stolen piece of gyro meat and cuts slices for the sandwich.

The cop finally finds Shaggy and the puppy and insists that "this mangy stray is coming with me." Shaggy refuses and claims that the puppy is his dog and that his name is Snacks. When the cop doesn't believe the name, Shaggy corrects himself and says that his name is Scooby-Dooby-Doo. The cop then lets them be, as the law is that dogs with middle names can't be arrested. Shaggy tells the puppy, now named Scooby, that he can be his dog if he liked. Scooby agrees and they head home to Shaggy's house.

Once at home, Shaggy shows Scooby his room, which is filled with memorabilia of Blue Falcon and Dynomutt, Shaggy's favorite superheroes. Shaggy then gives Scooby a gift, a custom collar for him, which Scooby swears to never take off. While hugging, Shaggy then promises Scooby that he would never leave him no matter what.

On Halloween night, Shaggy and Scooby, dressed up as Blue Falcon and Dynomutt, go trick-or-treating with Wally Rogers (Shaggy's cousin), his pet silver Dalmatian Ruffy-Doo (Scooby's cousin), and Scooby's childhood friends Tom Cat and Jerry Mouse. They come to the Rigby House, a mansion that Tom claims is haunted. They begin to walk away when three bullies, led by the neighborhood bully Red Herring, steal Shaggy and Scooby's bag of candy and throw it into the Rigby House until a boy, who turns out to be a huge rival of Red, defends the group by beating up the bullies. After the bullies run away, the six friends meet Fred Jones and his fraternal twin brother Riff, Daphne Blake and her fraternal twin sister Bridget, and Velma Dinkley and her little sister Madelyn, a group of friends, who want to make sure they're okay after being picked on. They offer to go into the house and try to get their candy back.

When they walk into the house they are attacked by a ghost who chases them around. During the commotion, Velma notices that the ghost is attached to a moving wire system in the ceiling. Fred cuts the wire with an ax that was hanging on the wall and the ghost falls down, only to be tied up by Madelyn, Daphne and Velma, and attacked by Riff and surprisingly Bridget.

Upon looking more carefully at the ghost they discover that he isn't a ghost and is actually Mr. Rigby, wearing a mask. Tom, Jerry, Wally, Ruffy, Shaggy and Scooby discover a secret hidden room, filled to the brim with expensive, stolen electronics (much to the excitement of Wally at the sight of electronics). The police arrive and take away Mr. Rigby. The twelve friends, happy with their success in stopping a crime decide to pursue mystery solving.

A montage ensues in which the gang solves a variety of cases and takedown classic monsters from Where Are You. Throughout the montage, they transition into young adults.

Fast forward to ten years later in Machu Picchu, Peru, two archeologists Dr. Fitzhugh and Sandra found a giant-sized canine skull which they both believed that it belonged to mythical three-headed dog, Cerberus, the guardian to the gates of the Underworld. Sandra couldn't understand how one of the skulls end up in Peru to begin with. Fitzhugh showed Sandra murals on the walls that the skulls were separated and hidden in three mythical places around the world. And according to the legend, that if the three skulls were ever to be reunited, the gates of Hades would rise again and plunge the world to darkness. Sandra was confused of why'd anyone want that to happen. Fitzhugh then acts very strange all of a sudden and tells her that behind the gates, lies an enormous treasure horde which would make him the wealthiest man in history, and he then pulls a weapon from his sleeve and aims it at her. Dr. Fitzhugh reveals himself to Dick Dastardly and Sandra presses the alarm button, but no sound was heard as the alarms were disabled and the security guards are incapacitated by Dastardly's devious group of villains called the Vulture Squadron. Dick shoots a sticky substance at Sandra that sticks her to the wall. Sandra tells him the skulls are useless without a certain key. However, Dick assures her that the prophecy is already been fulfilled and knows where to find it.

After an awkward moment with one of his robots, Dastardly signals his giant air ship, the Mean Machine and drops one of the claws onto the skull and the Vulture Squadron hops on as the claws lifts up the skull. Dick then chants the skull to where the other two are hidden then it projects green beams of supernatural light and circles around the area then stops to the pointed direction. After getting a set of coordinates, Dastardly bids Sandra farewell who warns him that Blue Falcon will stop his plan.

Months later in Venice Beach, Scooby and the gang are at the R&S Coffee shop diner, contemplating what their next adventure will be. Angel Dynamite and her close friend Vanessa Quinlan (a high school principal) arrive to talk to the gang about their adventures as the Mystery Gang. Fred, Riff, Velma, Madelyn and Daphne are all ready to make the Mystery Inc. Detective Agency a more professional business. Velma explains that they require money to take on bigger mysteries. Madelyn explains that Simon Cowell, the celebrity television host and entrepreneur, is considering to be their possible investor. Cowell shows up to the diner and explains that for him to invest in Mystery Inc. they need to be a better group for Fred is the leader/planner, Riff is the muscle, Daphne is the prettiest one, Bridget is the empath, Madelyn is the comic relief, Velma is the brains, Wally is the mechanic, Ruffy is the adventurer dog, and Tom and Jerry are the fun-loving supporters. Sheriff Bronson Stone was driving by his patrol car when he notices the gang inside the diner and walks to see what they're up to this time when he notices Simon Cowell. Simon says that Shaggy and Scooby aren't pulling their weight and that they bring nothing to the dynamic of the team, and Sheriff Stone agrees with him (much to Ruffy, Wally and Bridget's dismay). Simon couldn't invest Mystery Inc. as long Shaggy and Scooby-Doo are involved; claiming that friendship won't save the day. Feeling unwanted, abandoned and heartbroken by Simon's words, Scooby and Shaggy leave the diner despite the pleads of the others.

The two then went to the Takamoto Bowl, a bowling alley where they usually hang out and cool off. Wally, Ruffy, Bridget, Angel and Vanessa find the two as they try to comfort them by telling them that Simon Cowell is wrong about them. Scooby knocks down all of the bowling pins but one in his first shot. He knocks down the second one, but it jumps back up as if it was alive. Suddenly, a pair of red eyes appear in the bowling pin, but before Scooby can show the others, they disappear. Scooby waits for his ball to come back in the ball return. When it doesn't come back for a while, they start to suspect that something is off. Suddenly, the bowling pins and balls transform into little killer robots! They begin firing lasers at the seven, who slide down a bowling lane to escape them. They pretend to be cashiers, working at the bowling alley, and try to take food orders from the robots. But the robots catch on to their charade and start chasing them again.

While this is going on, Tom, Jerry, Fred, Riff, Velma, Madelyn and Daphne get an alert from the police scanner that there are robots attacking the bowling alley. Remembering that Shaggy and Scooby usually like to go there, and that Wally, Ruffy, Bridget, Angel and Vanessa went to find them, they fear that their friends are in trouble and rush over to help them.

Shaggy, Scooby, Wally, Ruffy, Bridget, Angel and Vanessa go into an alley, but there was a dead end. They are about to be caught by the robots when all of a sudden, a blue light beams them up into the sky. They are inside the interior of a futuristic airplane. Upon looking around, Shaggy realizes that they are inside the Falcon Fury, Blue Falcon's airship. The seven are welcomed by the Teen Angels: Ariel Steele, the leader of the Teen Angels who is the strategic planner/coordinator of the Falcon Force operations; Brenda Chance (Vanessa's niece), the pilot/navigator and aerial expert; Dee Dee Skyes, the infiltration, engineering and technology expert; Jazz Swift, the master of disguise and undercover operations; Leona Harmony, the communications and language expert; Taffy Dare, the combat and martial arts expert; and Brenda's pet talking parrot Quillstone, the surveillance and reconnaissance expert.

Ariel explains that the robots were sent by the supervillain Dick Dastardly and his crew, the Vulture Squadron who seemingly wants to kill Shaggy and Scooby, although she and the other Teen Angels do not yet know why he wants to do so. They arrive at the control center of the ship, where Blue Falcon makes an entrance.

While Shaggy and Scooby are initially excited to see Blue Falcon, they are confused, as he looks very different. Dynomutt appears and reveals that actually, he is the son of the original Blue Falcon, Brian Crown, and that he has taken over the position of being a superhero. Brian, now the new Blue Falcon, explains that his father, Radley Crown is now retired to Palm Beach, while Dynomutt on the other hand still misses him dearly.

All at once, an alarm goes off in the ship alerting that the Vulture Squadron is close by. Dee Dee explains that they tracked Shaggy, Scooby and their group from the bowling alley. They all run up to the helm of the ship, the Falcon Fury and a chase ensues!

Inside the helm of the Falcon Fury, Dynomutt, Blue Falcon, and the Teen Angels explain to Shaggy and Scooby that Dastardly is collecting the skulls of Cerberus, although they still don't know what they have to do with Shaggy and Scooby, or why Dastardly wants them. They reveal that Dastardly already has one and that if they don't stop him, he'll get the other two. Their mission is to collect them before he can.

The Mean Machine latches onto the Falcon Fury using harpoons and is about to drag it in when Brenda had an idea then tells Quillstone to reverse the polarity of the tractor beam, so that it pushes them away from the Mean Machine.

This works, and they escape Dastardly and the Mean Machine for the time being. They head back to the center of the ship, and Dynomutt comes to the conclusion that actually Dastardly wants Shaggy and Scooby alive, as he could have killed them earlier instead of just trying to capture them. Blue Falcon then says that Shaggy and Scooby are important, though they still don't know why, and that they'll need their help on their mission. Being good old friends of the Teen Angels, Angel and Vanessa (who is actually a well-known detective and adventurer) are both honored to join. Shaggy is reluctant to agree, as he still feels like the "weak link," but Scooby, Wally, Ruffy and Bridget talks and convinces him into joining as a chance to prove Simon Cowell and Sheriff Stone wrong.

Meanwhile, back at the Takamoto Bowl, Tom, Jerry, Fred, Riff, Velma, Madelyn and Daphne are asking questions to the owner, Judy Takamoto to figure out what happened to their friends. They feel guilty for their disappearance, as they made Shaggy and Scooby feel unwanted, and Wally, Ruffy and Bridget are the only ones who understood them more. When inquiring about the robots, Judy hands them a cardboard box with the remains of one of the Rottens. Sheriff Bronson Stone and the police comes in and tells them clear the premises for the bowling alley is a crime scene. Velma closes the box and she and the other six leave as Sheriff Stone looks on in suspicion.

Back in the Mystery Machine, Fred, Riff, Daphne, Velma, Madelyn, Tom and Jerry investigate the Rotten. They discover a loose hair on the robot and track it back to Dastardly Demolition, previously owned by Dick Dastardly. They find out that along with the footage of stealing the first skull of Cerberus he's also been stealing the genealogical records of many dogs from the Canine Global Kennel Club. They decide to go after him and help their missing friends and they drive off, unaware that Sheriff Bronson Stone begins to follow them and tells one of his deputies on dispatch that he's in charge until he returns.

Inside of the Mean Machine, Dastardly is lamenting over the fact that Scooby got away. He becomes upset at the Vulture Squadron because, in his mind, they are not nearly as good as his last sidekick, Muttley, a dog, who is no longer with him. One of the Rottens apologizes for their failure, but that only upsets Dastardly more. He calls him a "suck-up," and to prove a point to the other Rottens, he removes his head and replaces it with the top of a vacuum cleaner.

At the Falcon Fury, Ariel, Brenda, Quillstone and Dynomutt are searching for the second skull by locating areas with high fossil density. Blue Falcon, on the other hand, is trying to find the skull by asking his social media followers if they know where it is, with Jazz, Taffy, Ruffy and Bridget joining in the action, while Dee Dee and Wally are repairing the damages done to the Falcon Fury's wings. Shaggy and Scooby come in with their hands full of food. They prepare a "Scoob-Shag Specialty," ice cream and a jalapeño pepper. Thanks to an idea from Shaggy and Scooby, Leona figures out that the second skull is in the Gobi Desert by tracking its heat signature and they urge Blue Falcon to go there with them. However, Blue Falcon decides instead to listen to a DM that says that the skull is in an abandoned amusement park in Romania.

Meanwhile, in the Mystery Machine, Velma reveals that by cross-matching the biographical data that Dastardly stole from the canine registry against Scooby-Doo, she is able to determine and discovered that Scooby is the last descendant of Peritas, the dog of Alexander the Great. Jerry makes the point to her friends that this is "our most important mystery ever," as it involves Scooby. Fred changes course, as he claims he "knows a shortcut" but notices that the Mystery Machine is running low on gas and drives to the Service Station next to them.

As Fred refuels the Mystery Machine, Tom sees an orange Dune buggy behind him and comments on the tires and hears a voice that thanks him for the compliment. This freaks out Tom when he discovered that the Dune buggy can talk alerting the gang, followed by five other teens exiting the store. They introduced themselves to the gang as the Speed Bugs; Debbie, the pit crewwoman, her friends fellow pit crew members Mark, Serena and Max, their mechanic/driver Tinker and their mascot Speed Buggy. They are familiar with Mystery Inc., but Debbie notices that Shaggy, Scooby, Wally, Ruffy and Bridget aren't with them. Madelyn tells them that it's long story and that they were on their way to Dastardly Demolitions, which the Speed Bugs are well aware of Dick Dastardly and his Vulture Squadron and have been there many times to collect spare auto parts for Speed Buggy, and they ask to join the Mystery Gang, to save their friends as they like to solve mysteries and stopping villains for they'll all the help they could find. Mark already knows a quicker route and Velma can tell him and the other Speed Bugs everything she knows along the way. As they start to drive off, the Rotten, unbeknown to them, reactivates again. Sheriff Bronson Stone continues to follow them but has to get gas too.

The Falcon Fury arrives at Funland, the abandoned amusement park in Romania. As soon as they walk inside the park, the Mean Machine ascends from the sky. The Vulture Squadron and the Rottens fly down and Dastardly reveals that he was the one who sent Blue Falcon the DM and that he has just retrieved the second skull from the Gobi Desert.
