Scoob! Plot Summary and Synopsis

Ten years ago, a young, lonely Shaggy Rogers befriends and adopts a talking stray Great Dane pup, whom he names Scooby-Doo. On Halloween night, Scooby and Shaggy meet three young detectives named, Fred Jones, Daphne Blake, and Velma Dinkley, before venturing into a haunted house. Inside, the kids encounter a ghost, whom they capture and unmask as costumed thief Mr. Rigby. Inspired by the experience, they decide to form a group, Mystery Inc., to solve mysteries together.

In the present day, Mystery Inc., having solved numerous mysteries, goes into business with entrepreneur Simon Cowell as their investor, but Cowell refuses to do business with Scooby and Shaggy involved. Later that night, Shaggy and Scooby are terrorized at a bowling alley by shape-shifting scorpion robots called Rottens. The pair are rescued by Dee Dee Skyes, Dynomutt, and Brian, the son of the masked superhero, Blue Falcon, who has recently retired and passed the mantle to Brian. The Rottens are then revealed to belong to supercriminal Dick Dastardly who wants to capture Scooby as part of a plan involving the Great Dane’s mysterious connection to the supernatural mystery behind Cerberus’ three skulls.

Meanwhile, Fred, Daphne, and Velma head off to Dastardly Demolition and investigate what Dick Dastardly wants with Scooby and Shaggy, as they reminisce about the good times they had with Shaggy and Scooby before discovering that the pair are investigating the mystery behind Scooby himself with The Falcon Force, with Dastardly imprisoning the trio. Escaping with help from one of the Rottens, they make contact with Dee Dee, via Dynomutt. Velma explains that she and the others are being taken to Messick Mountain, where the last skull is located. The group then finds out that Dastardly’s plan is to open the gates to the Underworld, in order to rescue his dog, Muttley, who was trapped during an attempt to steal the Underworld’s riches. Dick Dastardly needs Scooby to unlock the gates, since he is the last remaining descendant of Alexander the Great’s favorite dog, Peritas.

Scooby, Blue Falcon, Dynomutt, and Dee Dee arrive at Messick Mountain and head underground to a hidden Mesozoic island. There, they find the last skull being guarded by Captain Caveman. Following a short battle, Fred and Shaggy arrive, but Fred is revealed to be Dastardly in disguise as he steals the last skull. The Rottens then throw the real Fred, Daphne, and Velma out of his airship and Dastardly destroys the Falcon Fury. Dastardly then captures Scooby and takes him to Athens. After Shaggy speaks out about how he felt like Scooby’s importance would change things and tear him and Scooby apart, he gives an inspiring speech, and everyone works together to reconstruct the Mystery Machine, in order to pursue Dastardly.

Arriving in Athens, Dastardly uses the three skulls to reveal the gates to the Underworld and attempts to use Scooby’s paw to open it, only to be interrupted by Scooby’s friends in a flying Mystery Machine. The Rottens shoot them down while Dastardly releases Cerberus; unaware that Dynomutt landed them safely. As Scooby, Dastardly, and the civilians flee from the rampaging Cerberus, Scooby runs to the crash site and reunites with his friends, while Dastardly happily reunites with Muttley in the Underworld and they escape while stealing some of Alexander the Great’s treasure. While determining how to trap Cerberus, Velma discovers more of the mystery behind Scooby’s ancestry and its connection to the Underworld. With help from the Rottens, Mystery Inc. and friends successfully trap Cerberus back into the Underworld. However, Shaggy sacrifices himself to lock the gate, following the prophecy of Alexander the Great and Peritas’ bond. The gang realizes that there is another exit that continues their prophecy, which Scooby unlocks, and Shaggy is reunited with Scooby and the gang. The Rottens turn on Dick Dastardly, who is unmasked upon the revelation of stealing Simon Cowell’s identity to break the gang up and take advantage of Scooby for his spooky plot against the gang, since the start. Dastardly, along with Muttley, are taken into custody by The Falcon Force and are arrested.
