Needed: Synopsis is too short.

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


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 emerges from the hole and Kriegstaffebots come 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 (including the prisoners) 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 a now-heavily armored Mystery Machine to attack the robots. After the word is spread, the armored Mystery Machine invades the mines and attacks 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 is 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 are 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.
  • Frank Welker and Kate Higgins are uncredited as Barty Blake and Janet Nettles, respectively.
  • This marks the first time a single Scooby-Doo series has reached fifty episodes.
  • In the scene where Mr. E says that Cassidy is gone, he has what looks like his own diary with her pictures attached. In it is written the following text: "Thinking of Cassidy again. Remembering when we first met. Professor Pericles was there and I could tell he was jealous. He didn't want to share me with anyone." This shows that the relationship between Ricky, Cassidy and Pericles was a mirror of the relationship between Shaggy, Velma and Scooby in season 1. This also explains what E meant to say in the note he sent Velma at the end of The Grasp of the Gnome.


Cultural references

  • 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 Star Trek III: The Search for Spock. Fred even talks in a similar mannerism to Kirk.
  • Shaggy's line, "Danger, Danger, Run, Will Robinson, Run," is a reference to both the line "Danger, Will Robinson" from Lost in Space and the line "Run Forest, Run," from Forest Gump.
  • Scooby's line, "They drew first blood, not me" is a quote from the film, First Blood, starring Sylvester Stallone.
  • When the plane takes off after dropping the Mayor and the gang off in Crystal Cove, Shaggy reacts by saying "I feel the need, the need for..." but is interrupted by Scooby saying "pizza." This is a reference to the famous line from Top Gun, "I feel the need, the need for speed."
  • Scooby's springy legs when he jumps to Shaggy's rescue is like Inspector Gadget.

Animation mistakes and/or technical glitches

  • When at the 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.
  • As the people of Crystal Cove are beginning the uprising, Nan is seen without her hat.

Inconsistencies/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.
  • Despite having served in the Air Force, Nettles struggles with the rocks.
