The main antagonist of "Grundelesque".

* AdultFear: A tall creature in a coat who kidnaps your children and manipulates them into being bad.
-->"Come out and play."
* ArchEnemy: To Kylie. She has a personal enmity for him for abducting her friend Jack and transforming him into another Grundel, as well as trying to do the same to her. He has also taken his inability to transform her personally, and longs to make her suffer for it.
* BodyHorror: His victims are transformed into Grundels like him. Considering that he's a green, bloated, almost corpse-like abomination, the process is pretty grotesque.
* ButForMeItWasTuesday: Averted.

'''The Grundel:''' I do... ''Kylie''.

* EvilSoundsDeep: He speaks in a deep, creepy voice.
* FauxAffablyEvil: He really turns on the charm for Kylie and refers to Egon as like an old friend, but he's a monster.
* KnightOfCerebus: The second he appears, all humor drains out of the scene, and "Grundelesque", his sole appearance in ''Extreme Ghostbusters'', is the darkest episode of the series.
* LastOfHisKind: He's thought to be the last Grundel ever until Jack resurfaced.
* LeaningOnTheFourthWall: Egon says he and the original team busted him ten years ago. "The Grundel" aired in 1987 and "Grundelesque" in 1997.

* BrainwashedAndCrazy: A result of being transformed into a Grundel, he serves the original Grundel's disciple.

* EvilFormerFriend: To Kylie, though he's been brainwashed into this state. Thankfully, defeating the Grundel again erases his hold over Jack.
* NoOntologicalInertia: Played with. One of the show's rare aversions, he was not returned to normal when the original Grundel was busted because he was in a cocoon. Busting the original in the episode proper does return him to normal, though.
* SealedEvilInACan: He was left to gestate in a cocoon inside a tree. A lightning strike ends up releasing him.

!!Morpheus
The main antagonist of "In Your Dreams".

* ClippedWingAngel: He was virtually unstoppable so long as he was in people's dreams or possessing the radio host. Once he fully crossed over, though, he was easily foiled.

* AnimalisticAbomination: It resembles a giant whale.
* {{Expy}}: Of Literature/MobyDick. It's even chased about by Maiikrob, an expy of Captain Ahab.

* LifeDrinker: Not for herself, but she nonetheless attempts it.
* MirrorScare: She can travel through mirrors, so this happens a fair number of times.

The force behind the main antagonist of "Till Death Do Us Start".

* JackassGenie: Considered one as it grants wishes in the worst possible way.
* LifeDrinker: Through the granted wishes, it tries to absorb the life force of the given target.

!!Lilith
->'''Voiced by:''' Nora Dunn

!!Sphinx
->'''Voiced by:'''
The main antagonist of "The Sphinx".

* OurSphinxesAreDifferent: A sphinx wearing a pharaonic headdress which asks humans the famous RiddleOfTheSphinx.

* RiddlingSphinx: He asks the classical RiddleOfTheSphinx in order to test mortals' minds, afterwards absorbing the brightest ones, and goes into a VillainousBreakdown when Egon gets it right.
* SadlyMythtaken: He's meant to be based on the Greek Sphinx, but wears Egyptian regalia.
* SoreLoser: The Sphinx gloats when no one was able to solve his riddle but, when Egon correctly answers, he immediately demands to ask another one.
* VillainousBreakdown: He completely loses it when Egon correctly answers his riddle.

* GodsNeedPrayerBadly: He needs four believers in order to gain power.
%%* HumanoidAbomination: His eyes are shaped like ''diamonds''!%%... so?
* OneWingedAngel: He assumes a demonic appearance near the end of his episode.
* SadlyMythtaken: Cernunnos may be a fairly obscure figure to modern scholarship, but he certainly wasn't a demonic tempter like he is in this portrayal.
* VillainousBreakdown: When getting pulled into the ghost trap, he desperately tries to get free by offering the Ghostbusters more power if they let him go. This time, no one listens.
