Scooby-Doo! Mystery Incorporated/Recap/S1/E26 All Fear the Freak

In the second part of the season close-out, the gang confronts its darkest hour when the Freak of Crystal Cove is unmasked; the revelation is only one of many, many shockwaves that will set Season Two up to be a lot more dramatic than we're used to from a Scooby-Doo cartoon.

Tropes used involve:
"Mayor Jones: I raised you!
 * Break the Cutie: Where to start? Fred (or whatever his name is) found out that Brad and Judy are his real parents, he broke his engagement with Daphne, Shaggy is about to be packed off to military school and everybody blames Velma for what went wrong.
 * Chronic Backstabbing Disorder: Not only did he arrange things with Pericles to betray the original Mystery Inc., Fred Senior screwed Pericles over and packed him off to the animal asylum.
 * Did He Or Didn't He?: What Professor Pericles did to Ed Machine offscreen has yet to be detailed. All we know is that it wasn't pretty.
 * Offscreen Teleportation: The Freak manages this with Shaggy and Scooby.
 * The War Has Just Begun: Scooby's reaction to being taunted by Pericles is to vow to reassemble the gang and hunt him down.
 * Was It All a Lie?: The following exchange:

Fred: You used me."


 * Let's not forget Stone's reaction to the whole thing.
 * Wham! Episode: Let's see now: Fred (or whatever his parents named him) has left town after breaking things off with Daphne (who. like Velma, is grounded for a year or so) and declaring the gang dissolved because it's tainted by association with a city he hates, Shaggy is being packed off to military school, Scooby to a farm, Mayor Jones has been outed as the most evil supervillain in the history of the franchise and everyone except the dog blames everything on Velma; about the only thing that keeps this from being the worst ending ever is that Scooby is determined to make things right....with extreme prejudice.
 * Wham! Line: "Mystery Incorporated is dead."
