The 13 Ghosts of Scooby-Doo - Season 1

Scooby and Shaggy struggle to reincarcerate thirteen of the foulest demons ever to plague the earth after they accidentally release the demons from a chest.

Mordor the Malevolent lures the gang into his evil forest in hopes of destroying the only ones who could jeopardize his new-found freedom.

When the chest of demons is stolen by the Shadow Demon, Vincent steers the gang toward Befuddle Manor before the crystal ball gives out. In their search for the chest, they are captured by the Queen of Ghouls.

While at a paranormal convention, the gang is chased by the evil Reflector Spectre and his henchmen, Weerd & Bogel.

Zomba, the host of the "Spine Tingler Movie", is one of the escaped demons who sweeps the gang into their TV, where they are trapped in an old Frankenstein movie.

Scooby's nerves are frazzled so the gang goes on a cruise. Unfortunately, their travel agent is one of the thirteen ghouls, and he sends the gang on a trip into the Bermuda Triangle.

At the Mardi Gras, Vincent is smitten by the lethal love trance of Nekera, a beautiful femme fatale. The gang thinks they must keep him from her kiss; however, Vincent knows that kiss will be Nekera's undoing.

Three hags are given magical powers by a witch trapped in another dimension. When the gang learns of their plot to overthrow the world, Vincent sets out to thwart the mist witch.

When the Time Slime tries to zap the gang, they take his Time Scepter and use it to show Scooby (who believes he is more of a hindrance than a help to the gang) what their lives would be like without him.

A demon uses magic ink and draws himself into the newspaper comics. The paper is delivered to the gang by Weerd and Bogel.

Outraged by being denied membership to S.A.P.S., Weerd and Bogel steal some important mystic paraphernalia. This same material is needed to keep Vince from fading away. The S.A.P.S. and Scooby and the gang all chase the two inept ghosts.

Upon Scooby's return to his home town, a demon circus comes to plague Doosberry. It's up to the gang to save the city from being taken over by the phantom three-ring villains.

The gang goes on Boris Kreepoff's TV show in hopes of finding one of the demons and they have their chest of demons stolen. In their search for the chest, they find both a demon and a villain trying to steal the chest for his own gain.
