Gates of Gloom is the twenty-fourth episode of the second season of Scooby-Doo! Mystery Incorporated, and the fiftieth episode overall in the series.


While Mystery Inc. are away, an earthquake sucks down citizens of Crystal Cove beneath the earth!


The gang arrives at an airport in Crystal Cove, alongside Mayor Nettles and Velma's mom. After dropping off Velma's mom at the Spook Museum, it's become clear that Crystal Cove has become deserted, and everyone in town has been "eaten" by the ground. Later that day, after witnessing Mayor Nettles and Sheriff Stone vanish, the gang goes to Fred's house to discuss the Planispheric Disc, Nibiru, the cursed treasure, and an upcoming planetary alignment. The ground then starts to shake and open, which fails to suck the gang. Soon an armored mole-like truck emerged from the hole and Kriegstaffebots went out, shooting at the gang. Fred uses the traps in his house to literally cut the robots into pieces.

The gang sets off beneath Crystal Cove, and discovers everyone in town working for Professor Pericles and the rest of the original Mystery Incorporated. After hearing a conversation between the old Mystery, Inc., the gang devise a tactical plan to bust everyone out and shut down the operation. Shaggy and Scooby go undercover as Kriegstaffelbots, while Fred and the girls use an now-heavily armored Mystery Machine to attack the robots. After the word is spread, the armored Mystery Machine invades the mines and attack the robots. At the same time, Sheriff Stone leads a rebellion against the Kriegstaffelbots and Pericles, destroying every Kriegstaffebot they encounter. Shaggy is discovered to be a fake and was ordered to be shot to death, but an angry Scooby defends his buddy and wildly shoots down all the Kriegstaffelbots aiming at Shaggy. The battle tilts in favor of the citizens of Crystal Cove as hundreds of Kriegstaffelbots were destroyed and the mines sabotaged. Soon, a remaining number of Kriegstaffelbots stop Fred, Velma, and Daphne in their tracks, forcing them to blow up the Mystery Machine (in which everyone thought they were). It turns out that the Mystery Machine was remotely controlled by Fred, Velma, and Daphne in a different car. After all is resolved and the doorway to the cursed treasure is opened, the gang gears up with the relics and follows the original Mystery Incorporated into the caverns.

  • This is the first in a three-part story which is continued in Through the Curtain and concluded in Come Undone.
  • Scooby announces the "previously on..." recap.
  • Space Kook makes an appearance in a now destroyed Spook Museum.
  • The dialog between Fred and Daphne after the destruction of the Mystery Machine: "What have I done?" "What you had to do. What you always do, turn traps into a fighting chance to live," is a reference to similar words between Kirk and Bones after the destruction of the Enterprise in The Search for Spock.

Animation mistakes and/or technical glitches

  • When at Jones' mansion Velma is talking to the rest of the gang, Shaggy's eyebrows are missing, and it is unlikely for his hair to hide them.

Inconsistences/continuity errors and/or goofs

  • Velma substitutes the Spook Museum name for the Broken Spine which is actually the name for the bookstore within the museum (and where the gang primarily visits), but she addresses it as if the bookstore's name represented the entire museum.

    • I know that I don’t like cute couples, but I didn’t know that there was a kiss scene between Fred and Daphne. I’m kinda glad for these two.
