Come Undone

The gang and original Mystery Incorporated stand before the Evil Entity. The Entity grabs Scooby-Doo, and mentions that he must die and be reborn as a vessel for its darkness. Scooby breaks free, but Pericles volunteers to be possessed by the being, to which the Entity agrees. Professor Pericles believes he has gained ultimate power (due to his growth in size and appearance), but the Evil Entity kills Pericles and mutates his body into a squid-like monster. The Entity then assumes control of the Kriegstaffelbots and summons other evil Anunnaki, who proceed to offer the townspeople for the Entity to consume. When Scooby destroys the sarcophagus, a vortex opens and sucks in and destroys the Entity, his minions, and much of the rest of Crystal Cove, except for the gang, then explodes. The gang find themselves in a new version of Crystal Cove and Earth itself. After some strange encounters, Mystery Incorporated realizes that all the evil ever caused by the Entity has come undone, thereby changing history. The gang sets up a new Mystery Machine and travels off to their new destination after receiving a message from Harlan Ellison, vowing to solve each mystery they come across. As the gang drives away, they are watched by Nova, who says Scooby is the bravest dog that ever lived and thanks him and the gang.
