Scooby-Doo! The Sword and the Scoob

'Scooby-Doo! The Sword and the Scoob' is a 2021 American direct-to-DVD animated comedy film produced by Warner Bros. Animation and distributed by Warner Bros. Home Entertainment. It is the thirty-fifth entry in the direct-to-video series of Scooby-Doo films and was released on February 23, 2021.

Plot
After solving another mystery (similar to The Twilight Zone's "Nightmare at 20,000 Feet"), DNA evidence reveals Shaggy's ancestry comes from a village in England believed to have once been Camelot. The gang travels to the village to learn about Shaggy's ancestors and discover that Shaggy is descended from a legendary knight who thwarted an attempt by Morgan La Fey from stealing the throne of Camelot from King Arthur.

During the night, Morgan La Fey attacks the gang and sends them back in time to the time of King Arthur. Realizing they are playing a part in the kingdom's legend, the gang decides to follow history until they can find a way back to the future. The plan is complicated when Shaggy pulls Excalibur from the stone and inadvertently challenges King Arthur's right to the throne. The right to the throne will be decided by a competition between knights, but Shaggy only gets Fred on his team while Arthur gets the entire Order of the Round Table.

Before the competition can start, Morgan La Fey temporarily paralyzes Fred so he cannot compete, forcing Daphne to take his place while Velma begins apprenticing under the wizard Merlin to find a way to the future. Daphne single-handedly defeats the knights of the round table and Shaggy is declared king, but Morgan La Fey kidnaps him. The gang and King Arthur follows him to Morgan La Fey's lair and discover Shaggy has been duped into signing over his right to the throne in exchange for a banquet. Morgan transforms into a dragon to destroy the gang, but they manage to defeat her.

Afterward, Velma reveals she discovered the whole adventure was a staged experience by the townsfolk and that the gang was never sent back in time. Fearing Shaggy might claim the town as his birthright, the town used a Camelot experience attraction, actors, and special effects to get Shaggy to sign over the deed to the town. Shaggy explains he has no interest in claiming the town, but the town librarian who posed as Morgan La Fey steals the deed and drives the Mystery Machine to a Mailbox to take all the profits from the attraction for herself. Using an animatronic dragon, the gang stops her and a party is thrown to celebrate. During the party, Velma learns that the town did not hire a Merlin actor and the one she encountered might have been the real thing.
