History Characters / ScoobyDooAndTheGhoulSchool

-->Voiced by: Zale Kessler (Dracula and Frankenteen Sr.), Andre Stojka (Mummy Daddy), Creator/HamiltonCamp (Phantom Father), Creator/FrankWelker (Papa Werewolf)

* AmazingTechnicolorPopulation: Dracula and the Phantom Father are respectively colored purple and blue.

* FriendshipMoment: It's raining when they're all arriving at the school, so Dracula uses his cape to give the Mummy some extra covering since the guy's bandages aren't water-proof.

* DudeWheresMyRespect: Tug is the leader of the cadets but Calloway seems to approve of Jamal more.

* WeirdnessCensor: They do think the Grimwood girls are weird but don't seem to realize they're monsters.

* RedHerringMole: Since the BigBad has a [[AnimalMotifs spider motif]], one might be inclined to suspect that Legs will turn out to be EvilAllAlong. He is not affiliated with the BigBad in any way, and is fairly loyal to Miss Grimwood in spite of his stubborness.

Despite being one of the quietest, calmest girls, Sibella appears to be the leader of the bunch, as well as the oldest. She is helpful, polite, and while being a monster, is very sweet and the most easygoing of the girls. She's very sultry, and possibly the strongest of the girls, able to nearly [[spoiler:fight off the spider-bats when the others couldn't]].

** Though considering that the musical Phantom of the Opera took place in the late 1800’s there might be some fridge brilliance involved.

* TheLastOfTheseIsNotLikeTheOthers: In a school filled with (friendly) supernatural creatures like vampires, dragons and mummies, an amphibious octopus feels random.

Elsa is the tallest and presumably the second oldest of the girls. While she speaks like a simpleton and is prone to state the obvious, she is actually very bright, creating a "portable Shockman" in science class for [[FrankensteinsMonster her father]]. She is blunt and assertive and has no problem standing up to Revolta.

* ShoutOut: Her name is, "Elsa" is likely one to Elsa Lancaster; the actress who played the titular Bride in ''Film/BrideOfFrankenstein''.

The villain of the film. A spider-witch who seeks to make the Grimwood girls her personal slaves.

!Other:

!!Antagonists

* PinkMeansFeminine: She's a girl who wears a pink bow.

!! The Grimwood Girls' Dads
-->Voiced by: Zale Kessler (Dracula and Frankenteen Sr.), Andre Stojka (Mummy Daddy), Creator/HamiltonCamp (Phantom Father), Creator/FrankWelker (Papa Werewolf)

The monster girls' fathers, who show up to visit the school.

* AdaptationSpeciesChange: The Phantom is clearly a reference to the Phantom of the Opera, given his mode of dress, Phantasma's affinity for the pipe organ, and the fact that the film of ''Phantom'' is considered part of the Universal Studios Monsters series. But the original Phantom was a disfigured living man, not a literal specter.
** Though considering that the musical Phantom of the Opera took place in the late 1800’s there might be some fridge brilliance involved.
* AmazingTechnicolorPopulation: Dracula and the Phantom Father are respectively colored purple and blue.
* AmbiguouslyAbsentParent: None of the girls' mothers are acknowledged.
* BrokenPedestal: Revolta looks down on them, saying they used to be mighty monsters before they went soft.
* FrankensteinsMonster: Frankenteen Sr. is obviously a Frankenstein's monster, being Elsa's dad.
* FriendshipMoment: It's raining when they're all arriving at the school, so Dracula uses his cape to give the Mummy some extra covering since the guy's bandages aren't water-proof.
* GoodParents: All of them are loving fathers to their daughters.
* MonsterMash: Just like their daughters, these men are a vampire, a Frankenstein's monster, a mummy, a phantom, and a werewolf.
* KarloffKopy: Frankenteen Sr. sounds vaguely like Creator/BorisKarloff.
* LorreLookalike: The Phantom Father's voice is a clear Creator/PeterLorre impression, with his big round eyes accentuating the resemblance.
* PapaWolf: All of the monster fathers threaten to clobber Scooby and Shaggy should anything happen to their daughters. Mummy Daddy and Phantom Father even extend their threats to cover all five of the girls.
* UnnamedParent: Most of them aren't referred to as anything other than a synonym for "father", if they're ever given a designation at all.

--> Voiced by: Creator/CaseyKasem

An enigmatic entity that resides within a mirror in [[BigBad Revolta]]'s castle. When Shaggy stands in front of their mirror for too long, they trap him in the mirror and take his place in the real world, before proceeding to torment Scooby.
----

* PungeonMaster: Even in a script comprised almost ''entirely'' of puns, she stands out for her every other line being some sort of reference to her vampirism (as well as her CatchPhrase, "Fangtastic!")
