The Ghostbusters

    Egon Spengler 
https://static.tvtropes.org/pmwiki/pub/images/egb_egon.jpg
Voiced by: Maurice LaMarche, Martín Soto (Latin Spanish)

  • Cool Old Guy: Not exactly old, but he is one of the co-founders of the original Ghostbusters, and has helped catch ghosts in the field.
  • Mentor Archetype: Teaches to the next generation of Ghostbusters in his techniques, and provides them with ectoplasmic extermination technology.
  • Missed the Call: He intended to go after the spud in "Slimer's Sacrifice", but an encounter with Fenris left him too sick to try.
  • Oblivious to Love: As on RGB, he often misses Janine's overtures. He manages to eventually notice late in the series, but only after he was basically told to.
  • Retired Badass: He starts the series as a teacher at New York University and also watches over the Containment Unit after the other original Ghostbusters leave to follow other pursuits. However, he won't hesitate to venture out into the field when he has to.
  • Riddle of the Sphinx: He figures it out in "The Sphinx".
  • Sesquipedalian Loquaciousness: He sometimes speaks this way. Lampshaded when Eduardo asks Kylie to translate his "Egonics."
  • Specs of Awesome: Has acquired these over the years.
  • Team Dad: It comes with being their mentor.
  • Took a Level in Badass: At the start of the series, he's rather out of shape and practice. Over time, he regains a lot of his old ghostbusting proficiency.
  • You Are Better Than You Think You Are: He feels his age in "The Sphinx" and pushes himself (and the others) hard in the field to prove his worth. He ends up confiding in Garrett that he's exhausting and kidding himself at the same time. Garrett says the team does rely on him — not for butt-kicking, but for his wisdom and experience.

    Kylie Griffin 
https://static.tvtropes.org/pmwiki/pub/images/xgb_kylie_griffin_5213.jpg
Voiced by: Tara Strongnote , Ishtar Sáenz (Latin Spanish)

A Goth who was a big believer in ghosts and the supernatural even before joining the team; she's as knowledgeable in these areas as Egon (her idol) or Ray. She has a weaker and lighter Proton Gun than her teammates, but she's also the one who carries the Ghost Trap. When the team encounters unknown threats in the field, she's the most likely one to identify and strategize around them (or at least translate Egon's words to the others).

She's the only one of the team who is not a Suspiciously Similar Substitute for a member of the old team. Although she'd probably be considered "the Egon", if they didn't have the actual Egon.


  • Agent Mulder: A firm believer in the supernatural long before she ever laid eyes on an actual ghost.
  • Badass Longcoat: In the premiere episode only.
  • Belligerent Sexual Tension: With Eduardo. The two of them bicker like cats and dogs on a regular basis, but tend to enjoy each others' company in more ways than they care to admit.
  • Berserk Button: Don't use her late grandmother as a way to attack her.
  • Bruiser with a Soft Center: She's a tough and courageous Ghostbuster, but gets very sentimental when it comes to her late great-grandmother, Rose.
  • Canon Immigrant: Kylie appears in the Ghostbusters comics based on the original movie.
  • Custom Uniform: She and Eduardo do not wear standard uniforms. In her case, she wears a large breastplate (possibly modified hockey equipment) that lets her mount the much larger trap on her back.
  • Deadpan Snarker: Kylie often makes witty comments.
  • Freudian Excuse: Since she was raised by her great grandmother after her parents' divorce, her death caused Kylie to be obsessed with the supernatural.
  • Goth: Gloomy Goth variant, though it's worth mentioning she isn't nihilistic or pessimistic.
  • The Hero: Shares this role with Roland.
  • Ironic Fear: Of maggots. It might not normally count, but it's striking for someone so obsessed with the unusual.
  • It's Personal: The main reason she became a Ghostbuster was because said ghost tricked her by appearing as her beloved late grandmother.
  • Joisey: She occasionally slips into a New Jersey accent.
  • Kindhearted Cat Lover: Despite her appearance, Kylie loves her pet cat. Eduardo secretly gripes that she likes and treats her cat with more respect than him.
  • Mad Libs Catchphrase: Tends to say "I'm not a (blank)er."
  • Pint-Sized Powerhouse: She's so small that on the rare occasions she drives the Ecto-1, she needs to sit on a thick phone book. However, her size doesn't matter when she's ghostbusting because she goes into Action Girl mode. Her small physique, along with the increased size of the new ghost trap requires her to use a customized, much smaller version of a proton pack (specifically a pistol connected to a fannypack/back-of-belt pack, as opposed to the full-sized packs and throwers the others use). It’s shown to be about as effective as the full sized ones despite explicitly being less powerful overall. She's also shown to be strong enough to wield a full sized version in emergencies.
  • Pom-Pom Girl: An old photo shows that she was "Cheerleader of the Year" when she was in the 8th Grade. She regards this as an Old Shame.invoked
  • Raven Hair, Ivory Skin: Kylie sports black hair and has pale white skin.

    Roland Jackson 
https://static.tvtropes.org/pmwiki/pub/images/xgb_roland_jackson_3241.jpg
Voiced by: Alfonso Ribeiro (English), Thierry Desroses (European French), Carlos Íñigo (Latin Spanish)

The team's tech expert and unofficial leader after Egon, responsible for getting the Ecto-1 back in working order (and also installing a wheelchair ramp for Garrett) and doing the lion's share of upgrading the Proton Packs, PKE Meters and Kylie's Ghost Trap. Like Winston, Roland treasures the Ecto-1.


  • Ascended Fanboy: Of the Ecto-1, which he gets to upgrade and drive.
  • Badass Driver: Turns out to be suprisingly good at it in the episode with the Jersey Devil.
    Eduardo: Go Speed Racer! I knew you could drive, but I mean I didn't know you could drive!
  • Berserk Button: Don't mess with the equipment.
  • Big Brother Instinct: "Nobody touches my family or my friends!"
  • Black and Nerdy: Roland is an African-American teenager with an intellectual personality. Oh, and he enjoys opera music.
  • Companion Cube: The Ecto-1.
  • Dating Catwoman: With Syren in "Sonic Youth," though nothing much develops from it.
  • Genius Bruiser: Roland is tall and stocky, but extremely smart.
  • The Hero: Shares this role with Kylie.
  • Horrible Judge of Character: It's obvious to everyone else that Roland's younger brother Casey is an annoying troublemaker, but not Roland himself.
  • Ironic Fear: He's afraid of his equipment malfunctioning even though he's good with machines.
  • The Leader: Tends to give commands to the new team and is the most trusted by Egon.
  • Musical Assassin: Played with. Roland is a terrible violin player. Surprisingly enough, his bad violin playing actually hurts the Ghost Piper.
  • Only Sane Man: He's generally far more relaxed and easygoing than his teammates.
  • Suspiciously Similar Substitute: He certainly looks like a young Winston, but his personality and interests are different. His engineering skills also make him Ray's counterpart.
  • Techno Wizard: Can do almost anything with technology and quickly too. This can sometimes veer into Crippling Overspecialization as any entity that can cause the XGB's equipment to malfunction has him floundering, such as Lotan in "Moby Ghost".

    Eduardo Rivera 
https://static.tvtropes.org/pmwiki/pub/images/xgb_eduardo_rivera_4127.jpg
Voiced by: Rino Romano, Alfonso Obregón Inclán (Latin Spanish)

A slacker who only joined Egon's class for the "E-Z-A." He initially did not believe in ghosts but this changed when he had to go face-to-face with one. Like Peter, Eduardo can act like a smart alec at times and often speaks for the group, out of turn, he is also a frequent target of Slimer's pestering. His Catch Phrases are "Maybe he's/she's dead" and "We're scientists."


  • Belligerent Sexual Tension: His dynamic with Kylie in spades. For all their leveled vitriol, there's an undeniable chemistry at work.
  • Berserk Button: Don't call him "daisy."
  • Black Sheep: Eduardo feels he is this with his own family, who are cops. He is always at odds with his cop brother, Carl, who regards the Ghostbusters as nothing more than thugs.
  • Brilliant, but Lazy: Every now and then, he'll show to the rest of the team that he's much smarter than they give him credit for. However, he's not very motivated to do so.
  • Canon Immigrant: Like Kylie, he appears in the Ghostbusters comics based on the original movie.
  • Catchphrase:
    • "Maybe he's dead."
    • "We're scientists."
  • Character Development: Starts out as a lazy Jerkass, but grows out of it.
  • Chivalrous Pervert: He's a hopeless skirt chaser; however, he cares far, far more for a girl's personality than her looks. When a trio of Alpha Bitch witches tricks him into going on a "date" purely to use him as a fourth to summon an evil ghost, in the aftermath, he asks out... the homey girl they were picking on, telling the very physically attractive Ungrateful Bitch leader of said coven who snubbed him after he saved their lives, and restored them to humans, that she is not worth his time, to her face. Kylie can be seen smiling proudly in the background.
  • Cool Uncle: Seen this was by his nephew, Kevin, especially after finding out he's one of the Ghostbusters.
  • Custom Uniform: He and Kylie do not wear standard uniforms. He typically wears an orange vest over a T-shirt.
  • Deadpan Snarker: More so than Kylie. If he sees something worth ribbing, he'll rib it.
  • Everyone Has Standards: He won't hit on or a kiss a girl if she's not of legal age.
  • Freudian Excuse: His lazy and sarcastic attitude seem to make more sense upon seeing his brother, who mentions what a disappointment he is comparison to him and their father. Given Carl is a cop and has a stuck up attitude, Eduardo developed into the exact opposite in response.
  • Gratuitous Spanish: He often uses Spanish words, being a Latino.
  • Hidden Depths: Is surprisingly an avid reader. He even lampshades this in one episode. Not of the heavy stuff, it's mostly novels, though he did mention he read Homer's "Oddity"...
  • Hidden Heart of Gold: He comes across as very abrasive and selfish. When nobody's looking, though, he's actually a real softie.
  • I Am Not My Father: Eduardo's brother Carl never fails to belittle him about his life, lecturing Eduardo that he should make something of himself by becoming a cop like him and their dad. Eduardo angrily retorts that that's their dream, not his.
  • Ironic Fear: He is afraid of death, particularly his own, which is ironic because he often jokes about disappearances by saying "Maybe he's/she's dead."
  • The Lancer: He's lazy and far from leadership material, but when things go dire, Eduardo is usually the team's best on the action.
  • Manchild: Downplayed and justified, as he's still a teenager. But he does still enjoy scary novels aimed at children, reads Marmaduke and is a picky eater.
  • My God, What Have I Done?: He denounces Slimer as useless in "Slimer's Sacrifice," which motivates the titular sacrifice. He feels so guilty that he eventually goes into the Containment Unit himself to get him back.
  • The Slacker: It's the reason he took Egon's class to begin with.
  • Snark-to-Snark Combat: With Kylie. He teases her to no end, and she responds in equal measure.
  • Suspiciously Similar Substitute: To Venkman. Both are snarky and often irritated by Slimer. Both are also highly reluctant to admit fault in anything.

    Garrett Miller 
https://static.tvtropes.org/pmwiki/pub/images/xgb_garrett_miller_8488.jpg
Voiced by: Jason Marsden, José Antonio Macías (Latin Spanish)

Born a paraplegic, he's the jock of the team who is the most gung-ho about busting ghost tail. His attitude and demeanor are similar to Ray and Peter put together.


  • Ascended Fanboy: He was a huge fan of the Ghostbusters; now, he's a member of the new team.
  • Big Eater: Is often seen eating something.
    Eduardo: If it's nougat filled he'd eat it.
  • The Big Guy: He is the most athletic and aggressive of the group. And possibly The Heart as well.
  • Boisterous Bruiser: He just loves busting ghosts—and showing off how badass he is with a variety of crazy stunts.
  • Bond One-Liner: He often gives these when he captures ghosts.
  • Brooklyn Rage: Is from Brooklyn Heights (as he declares in "Darkness at Noon") and can get real ticked off against ghosts.
  • Butt-Monkey: Tends to get thrown from his wheelchair at the worst possible time (or any time), has terrible luck with food and actually just has a lot of things go wrong for him in general.
  • Claustrophobia: His biggest fear.
  • Composite Character: Combines Stantz's love for his ghostbusting career with Venkman's cockiness.
  • Disabled Means Helpless: HA HA HA—No. Garrett shows he's quite capable and self-reliant despite his paralysis. However, in "Grease," he fakes this trope just long enough to escape from two FBI agents.
    Garrett: Never underestimate the abilities of the physically challenged!
  • Disabled Snarker: Garrett, a paraplegic, likes to make with the dry and witty remarks.
  • Everyone Has Standards: In "The True Face of a Monster", outright states that he'll do anything for an adrenaline rush, even sneaking into areas that are off-limits. But when the "fun" is destroying a house of worship, he's horrified and backs down.
  • Friendly Address Privileges: Only his friends are allowed to call him by "Garr" or "G-Man"; the latter nickname ends up getting rescinded for his old friend turned racist vandal in "The True Face of a Monster".
  • Glory Hound: He inherited Venkman's desire to get the most positive press possible at all times. When he finds out in the Bad Future that Eduardo is championed as a hero, but nobody knows who he is, he's beside himself with wrath and envy.
  • Handicapped Badass: Don't let his handicap fool you; Garrett can kick lots of ass, ghost or otherwise... as long as he's in a wheelchair, or just chair.
  • Heroic Resolve: Well, for starters, he's the only one in "Fear Itself" to overcome his own fear. The others just trade off.
  • In-Series Nickname: Garrett is sometimes known by his friends as "G-Man". He only lets his friends use the name when he coldly tells Spencer never to call him that again.
  • Inspirationally Disadvantaged: Somewhat. Extremely capable despite being wheelchair-bound, brushes off an extremely tasteless remark by Eduardo in the pilot and never lets his disability get in his way.
  • Ironic Fear: His claustrophobia in "Fear Itself" eventually manifests as a coffin.
  • Jerk with a Heart of Gold: Snarks about as often as Eduardo, but generally bighearted and fun-loving.
  • Lovable Jock: Really enjoys sports and the adrenaline rush.
  • Mad Libs Catchphrase: "_______ is for wimps!"
  • Small Name, Big Ego: Never shy about patting himself on the back.
  • Toyless Toyline Character: The only member of the team who didn't get an action figure, although a prototype exists.
  • We Used to Be Friends: His old friend in "The True Face of a Monster" turns out to be a racist and a vandal.
  • Weaksauce Weakness: Stairs. But let's face it, that's kind of a Real Life thing for any wheelchair-bound person.
  • Why Did It Have to Be Snakes?: Besides his Claustrophobia, Garrett, despite trying to hide it, displays a fear of being helpless, most notably in "In Your Dreams" where his nightmare is about being in a situation where he's been knocked out of his chair and then trapped in a situation with no chance to escape on his own (since the chair seems to have disappeared entirely) and no one to come help him.

    Janine Melnitz 
Voiced by: Pat Musick, Rocío Garcel (Latin Spanish)

  • Composite Character: She combines her character design from the later seasons of the previous show with her snarky personality and (admittedly, milder) accent from the earlier seasons of said show.
  • Deadpan Snarker: Janine makes funny and witty remarks.
  • Fiery Redhead: Has red hair, and is quite passionate at times.
  • Friend to All Living Things: Reprimands Eduardo in "The Crawler" for trying to squash a harmless spider. This makes Cohila think she'd be a worthy queen.
  • Lethal Chef: Janine can't cook at all. Her food is so bad, even Slimer doesn't want to eat it.
  • Retired Badass: Proves herself to still be capable of ghostbusting in "A Temporary Insanity."
  • Sexy Secretary: She's the Ghostbusters' secretary, and she's gorgeous.
  • Shout-Out: Red hair. Glasses. slightly shapeless green-coloured jacket. A-line dark skirt. Snark Knight. All it needs is a set of big clumsy knee-length boots and we have an adult Daria Morgendorffer.

    Slimer 
Voiced by: Billy West, Herman López (Latin Spanish)

  • Big Eater: As ever. He often swipes food from the others and can easily be bribed into doing things via the promise of a treat. He's such a glutton that it led him to getting affected by Ravana's appetite-affecting corruption, despite being a ghost as well.
  • Brainwashed and Crazy: In "Slimer's Sacrifice", he's brainwashed by Surt to attack Eduardo.
  • Category Traitor: Surt even lampshades this in "Slimer's Sacrifice." Egon also mentions in "Ghost Apocalyptic Future" how the captured ghosts aren't very fond of him.
  • Extreme Omnivore: Being infected by Ravana in "Glutton for Punishment" causes Slimer to eat every inanimate object in sight. It gets to the point where he endangers team operations and has to be put in a trap.
  • Heroic Sacrifice: In the appropriately-titled "Slimer's Sacrifice," he flies into the Containment Unit to keep all the other ghosts from getting out after a faulty ghost trap causes things to go haywire.
  • Non-Human Sidekick: To the Ghostbusters. He's a ghost and they're humans.
  • Shoot the Dog: The team has no choice in "Glutton for Punishment" but to stick him in a trap. Egon takes it pretty hard.
  • Sidekick Creature Nuisance: Certainly to Eduardo, like with Venkman in the original team.
  • Team Pet: Just like with the RGB.

Ghosts

Notable Villains

    Achira 
Voiced by: Susan Tyrrell

A Mesopotamian spirit trapped inside a stone tablet. The main antagonist of the two-part premiere episode "Darkness at Noon."


  • Body Horror: The disease she spreads causes victims to grow green patches with pulsing boils on them. It gets worse later on with the revelation that the boils are her offspring.
  • Demonic Possession: She possesses Kylie for a brief time.
  • Flight: Displays this power.
  • Green and Mean: Her skin is a sickly shade of green and her entire modus operandi revolves around toppling civilizations by spreading her viral offspring.
  • Plague Master: She spreads a virus that causes a disfiguring disease.
  • Sealed Evil in a Can: Until construction workers breach her prison. And it turns out that she wasn't alone, either.
  • Shock and Awe: Her minions (attached to her body) can electrocute people.
  • Starter Villain: Achira is the first villain to be faced by the new ghostbusting team.
  • The Virus: Achira spreads a virus that was actually her offspring.
  • Voluntary Shapeshifting: Achira makes herself appear as Grandma Rose to Kylie so as to get close enough to possess her.

    Tempus 
Voiced by: Clancy Brown

The main antagonist of "Ghost Apocalyptic Future."


    Fenris 
Appears in "Slimer's Sacrifice".

    Surt 
Voiced by: Joe Alaskey

The main antagonist of "Slimer's Sacrifice".


  • Cold-Blooded Torture: What he wants to inflict on Slimer. For starters, he has him brainwashed into trying to kill Eduardo.
  • Creepy Monotone: Surt speaks in a quiet and eerie voice.
  • Dimension Lord: Rules the dimension inside the Containment Unit.
  • Hoist by His Own Petard: His attempt to escape is foiled by Kylie sending Fenris into his path. Fire and ice make a bad combination.
  • Playing with Fire: He can project flames.
  • Remember the New Guy?: It's been debated. Egon mentioned having caught Surt years ago with the original team—an event never depicted on the original show. On the other hand, there's wiggle room to say it was simply after the original show's last episode.
  • Sealed Evil in a Can: He was trapped inside the Containment Unit by the original Ghostbusters years ago.
  • Suspiciously Similar Substitute: Has a fair amount in common with Samhain, being the guy who commands other ghosts. He also really despises Slimer.
  • Wrong Genre Savvy: He muses that Slimer's in the Containment Unit because the Ghostbusters simply tired of him.
  • Xanatos Gambit: Attempts to pull one once he learns of Eduardo's presence. If the door is opened, he and the other ghosts can escape. If the door remains closed, he gets to kill Eduardo and torture Slimer. The door is eventually opened, but not long enough for him to enjoy it.

    The Grundel 
https://static.tvtropes.org/pmwiki/pub/images/80837998_2b5c_45fd_ab02_042d6751a7f0.jpeg
Voiced by: Maurice LaMarche

The main antagonist of "Grundelesque".


  • Arch-Enemy: 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.
  • Body Horror: His victims are transformed into Grundels like him. Considering that he's a green, bloated, almost corpse-like abomination, the process is pretty grotesque.
  • The Bus Came Back: Was one of the few ghosts from the original series to return for Extreme Ghostbusters.
  • But for Me, It Was Tuesday: Averted.
    The Grundel: This is personal, isn't it? Why are you so interested in me, hmm?
    Kylie: I... I don't know.
    The Grundel: I do... Kylie.
  • Card-Carrying Villain: He takes great pride in corrupting children into other Grundels, and refers to it as stealing their souls.
  • The Chessmaster: While being interrogated by Kylie, he suddenly plants his influence in Roland's little brother, using him to open the Containment Unit so that he can escape.
  • The Corrupter: He serves this role to children, manipulating them into becoming Grundel like him.
  • Corrupt the Cutie: A tall creature in a coat who kidnaps your children and manipulates them into being bad.
    "Come out and play."
  • Does This Remind You of Anything?: It's even more blatant here that he's an allegory for child molesters.
  • Evil Sounds Deep: He speaks in a deep, creepy voice.
  • Faux Affably Evil: He really turns on the charm for Kylie and refers to Egon as like an old friend, but he's a monster.
  • Knight of Cerebus: 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.
  • Last of His Kind: He's thought to be the last Grundel ever until Jack resurfaced.
  • Leaning on the Fourth Wall: Egon says he and the original team busted him ten years ago. "The Grundel" aired in 1987 and "Grundelesque" in 1997.
  • Pragmatic Villainy: The Grundel wanted Kylie, but she was too good a kid, so he settled for Jack.
  • Sealed Evil in a Can: In the Containment Unit itself. He gets out briefly before being sent back.
  • Sequel Episode: To "The Grundel" from the original series.
  • Spanner in the Works: He always intended to come back for Jack later, but the RGB busted him soon afterwards.

    Banshee 

Voiced by: Mary Kay Bergman

The main antagonist of "Sonic Youth".


  • Jerkass: Especially towards her sister Syren.
  • Make Me Wanna Shout: Her wail can shatter solid objects.
  • Sibling Yin-Yang: With Syren. Banshee is volatile, rude and ill-tempered, while Syren is calm, peaceful and nice.

    S.I.D.N.E.E. 
The main antagonist of "Back in the Saddle, Part Two".
  • The Bermuda Triangle: Where it originated. This entity was the cause of all those disappearances.
  • Eldritch Abomination: Underneath its foggy exterior, it is a gray blob-like creature with a lamprey-like maw.
  • Final Boss: With "Back in the Saddle" as the series finale, it is not only the last opponent of the Extreme Ghostbusters, but the last villain of the original animated universe that started with The Real Ghostbusters.
  • Not Quite Dead: All the people that it absorbed turned out to be alive. They're set free once the two teams bust it.

Other Antagonists

    The Golem 
A gigantic clay Golem created by a Jewish rabbi to defend a synagogue against anti-Semitic vandals. The main antagonist of "The True Face of a Monster".
  • Anti-Villain: The Golem was created to protect a Jewish synagogue from racist attackers but proves to be impossible to control.
  • Guardian Entity: Created by a Jewish rabbi to protect a synagogue from anti-Semitic vandals.
  • Healing Factor: The Golem can heal any wounds extremely fast.
  • No-One Could Have Survived That: Roland says that when the Golem's caught in an explosion. It walks out immediately afterwards. However, the damage it takes from the explosion is the key to finally destroying it.
  • Super-Persistent Predator: Two of the guys who attacked the synagogue run the moment the Golem starts rampaging. Thing is, it follows them to a power plant after they flee.

    Crainiac, Corpuscle, and Gristle 
The creations of horror novelist J.N. Kline. The main antagonists of "Deadliners". In truth, they are interdimensional demons who come to life through the act of writing.
  • Berserk Button: They are calm as a cucumber for a trio of fiends that is until you mess with the writing of their book.
  • Body Horror: They inflict this upon their victims, surgically transforming them into grotesque abominations.
  • Dissonant Serenity: They always speak in a sedate, almost soothing monotone... even as they ramble on about their desires to experiment with the "wet clay" of human flesh.
  • Expy: Of the Cenobites. Craniac in particular has been likened to Butterball.
  • Eyes Do Not Belong There: Corpuscle's eyes are in the palms of his hands. Garrett uses this to his advantage at one point, throwing a hot teapot at him and making him burn his eyes.
  • Fat Bastard: Crainiac and Corpuscle are both extremely chunky-looking monsters, with Crainiac having a more "big fat man" style body and Corpuscle having a nearly spherical body that waddles around on two stubby legs.
  • For the Evulz: Have no reason for tormenting their victims besides finding it entertaining and/or out of a twisted sense of art.
  • Humanoid Abomination: Loosely so but they still have humanoid builds. And good gravy, are they horrifying to look at.
    • Crainiac looks the most human-like, but has a mask stitched into his face with his cheeks and lips stapled back to permanently expose his teeth. He also has a buzzsaw blade embedded in his skull like a mohawk.
    • Corpuscle is virtually spherical, with short stumpy legs, but long, spindly arms that are held at awkward angles, with eyes in the palms of his hands. He hasn't got a head, but instead has a puckered, fleshy sphincter of an orifice... which unfolds outwards into a nest of gory tentacles and allows a demonic fetus on an umbilical cord to emerge to attack his prey.
    • Gristle is a lean, skinned-seeming humanoid with a malformed skull, sunken eye sockets, stitched together lips, peeled-away cheeks to expose the sides of his jaws, and spindly mechanical arms tipped in what look like dentist drills.
  • Lean and Mean: Gristle is the tall, skinny one compared to the shorter, chunkier Craniac and Corpuscle.
  • Mad Artist: Their primary goal is to reshape humans into twisted monstrosities as a form of demonic artwork.
  • No-Sell: On one hand, the proton streams do some kind of effect, like making them explode. However, they can reassemble themselves almost instantly. They do seem capable of feeling pain, but it doesn't stop them for long. Since they aren't actual ghosts, this means they can't be captured in the Ghost Trap. Furthermore, due to the typewriter, nothing the Ghostbusters can do would actually put a stop to them since it wasn't written in the book.
  • Not Quite Dead: The end of the episode indicates that the ghosts are not actually defeated but merely sent back to their dimension and this is only just temporary as they can find another writer they can use to be re-summoned.
  • Teleportation: Crainiac briefly shows this ability to dodge Kylie's particle beam.
  • Reality Warper: They can change any situation to their liking through using J.N. Kline via manipulation. Their signature line basically admits this, "If it is not written, it cannot be done.".

    Kahlil 
The ruler of another dimension that strongly resembles Hell. The main antagonist of "Casting the Runes".

    Kahlil's messenger 
Kahlil's minion. Appears in "Casting the Runes".

    Luko 
A spirit that can possess machinery. The main antagonist of "The Infernal Machine."
  • Ghost in the Machine: He possesses machinery.
  • Hoist by Their Own Petard: He uses the very machines humans built.
    • He then gets a taste of this when parts of the machine built has the Ghost Trap.
  • Sealed Evil in a Can: He was imprisoned in an inventor's machine until he broke free by possessing modern technology.
  • Slasher Smile: He always has a very evil look on his face until he's finally caught.

    Le Maison 
The main antagonist of "Home is Where the Horror Is".
  • Bilingual Bonus: "Maison" means "house" in French. It's "la maison" actually — 'maison' is a feminine word in French.

    Evil Clowns 
The main antagonists of "Killjoys".
  • Emotion Eater: They feed on people who laugh.
  • Monster Clown: They are demons who disguise themselves as clowns to get people to laugh so they can eat them alive.
  • Our Vampires Are Different: Kylie surmises that they are a vampire analogy that feed on laughter instead of blood.
  • Viral Transformation: One of the clowns infects Eduardo, who then turns into one of them.

    Tenebraug 
An ancient spirit that stole the eyes of anyone who gazed upon its orb. The main antagonist of "The Unseen."
  • Eye Scream: It steals the eyes of anyone unfortunate enough to gaze upon its orb.
  • Hoist by His Own Petard: Tenebraug loses his own eyes and the ones he stole after gazing upon its own orb. It's then destroyed when the orb is smashed.
  • Sealed Evil in a Can: It was trapped inside an orb.
  • Teleportation: It can move around in the blink of an eye.

    Cohila 
Voiced by: Fernando Escandon

The main antagonist of "The Crawler".


  • A Father to His Men: Literally. And he hopes to lead them into battle himself.
  • Papa Wolf: He's protective of not just his own children, but all bugs.
  • Sealed Evil in a Can: He was imprisoned inside a sarcophagus until two greedy thieves removed the enchanted jewel in his mouth.

    The Piper 
Voiced by: Roger Rees

The main antagonist of "The Pied Piper of Manhattan".


  • Cut Lex Luthor a Check: Starts off this way, using his abilities to make money off the mayor.

    The Salesman/Duophanes 
Voiced by: Jonathan Harris

The main antagonist of "Be Careful What You Wish For."


  • Be Careful What You Wish For: The title spells it out for you, after all.
  • Blatant Lies: "Satisfaction guaranteed".
  • Body Horror: Many of his victims end up transformed in some way, like a man who wanted to get in touch with his roots being turned into a tree.
  • Clipped-Wing Angel: The Logic Bomb forces him to transform, and he's much more vulnerable this way.
  • Exact Words: He claims satisfaction guaranteed for his products, and he's perfectly satisfied with the pain he causes.
  • Faux Affably Evil: He's so polite and unassuming... before tormenting his victims.
  • Humanoid Abomination: Like the show's other villains, he looks like a normal human for most of the episode. It ends up acting as a shield against the proton blasts, so the EGB need to get him to reveal his true form.
  • Jackass Genie: He knows exactly what his victims want, but twists the meanings of the wishes for his own sadistic pleasure.
  • Literal Genie: Granted people's wishes in the literal sense. The results weren't pretty.
  • Logic Bomb: How he's defeated. Eduardo writes out a message about wishing that he doesn't grant a wish. After Kylie says it, the confusing nature of the paradoxical wish causes the Salesman to reveal his true form and become easy to trap.
  • Race Against the Clock: The EGB have to stop him from leaving town or else all the wishes remain permanent.

  • Sadly Mythtaken: In Norse Mythology, Hraesvelg is a giant in the shape of an eagle whose name means "corpse swallower" and whose wing-beats cause the wind to blow. In the show, Hraesvelg is a dragon whose name "literally translates from Old Norse as 'Bird of Prey'" and who has complete control over the weather.

    Shanbahac

  • Dream Stealer: Using Barry Sherman's voice as a conduit, Morpheus drew energy from the dreams of anyone listening to Barry's voice using the parasitic Somniwyrms. After he gathered enough energy, Morpheus manifested in the real world as a 20-foot tall version of himself.

  • Mad Eye: His left eye is noticeably larger than his right eye.
  • Reality Warper: In any dream he invades, Morpheus is untouchable and can control whatever happens in the dream. As he gathered more energy from dreams, Morpheus gradually gained the power to alter reality in the real world.
  • Your Mind Makes It Real: If a dreamer is injured in their dream because of Morpheus, such injuries often occur to them in the real world too, usually as bruises. After he goes bald in his dream, Eduardo becomes bald in the real world until Morpheus is defeated.

Voiced by:
The main antagonist of "The Sphinx".
  • Our Sphinxes Are Different: A sphinx wearing a pharaonic headdress which asks humans the famous Riddle of the Sphinx.

  • Forced Transformation: Forced to undergo one by the Grundel, who sealed him in a disgusting cocoon within an old tree for several years.
