With Halloween coming up thereโs only one real cartoon everyone thinks of and, of course, itโs the Real Ghostbusters. When they fight the literal spirit of Halloween, thereโs no contesting that it. But if you want some real horror without the Hallow, look no further than the Inhumanoids. Iโve long wondered how they could make this nightmare of a cartoon and sell it for kids, with all its terrifying monsters and body-twisting mutations. With so many horrific creatures filling out the cast of the show, itโs only fitting to try to find the one that stands out among the rest as the most grotesque of them all.
I originally planned to include the whole cast of the show, considering that the human villains and even its heroes are all particularly terrible people. Delusions of grandeur and anger management issues abound, not to mention their hideously designed suits.ย Unfortunately, that would make this list way too long.ย Instead, letโs just consider them honorable mentions in this list of the scariest monsters in the Inhumanoids.ย

10. The Granites
The Granites are one of the two races of Mutores, the group of creatures the Earth Corps can call allies, but that only depends on which side Granahue is betraying with his abundance of cowardice. The Granites themselves are your ordinary rock creatures, no more frightening than Krangโs Stone Warriors from Dimension X but with spears instead of lasers. Not to mention that two of their three leaders or fat old men.

9. Ssslither
Revered as the most fearsome of the Inhumanoids and once master of Metlar, Ssslither shows up near the end of the series, gets his ass kicked, and retreats to never be seen again in the next episode. Besides some cool backward legs, heโs your typical snake creature, King Hiss on steroids. Not nearly scary-looking enough to warrant going higher on the list and, while kinda cool, all he does of note in his scant appearance is blow up a random Granite with his lightning breath.

8. Magnicore
Another of the Mutore allies, Magnicore is two creatures, Pyre and Crygen, that control magnetic forces, the only thing powerful enough to stop Metlar. When the two are separated, one looked like heโs on fire, the one youโd expect to look like ice, but heโs just blue. Even when super-charged by the Galvacite crystal, they still look pretty lame, just growing bigger but without any distinctive characteristic.

7. Redwoods
The other race of the Mutores, Redwoods are living trees, and thankfully, a more loyal ally. Unlike the Granites, though, the Redwoods tend to look pretty freaky resembling a wooden version of the Green Goblin truck in Maximum Overdrive, but they donโt do anything in the show to inspire fear outside of their introductory scene, where they give Liquidator a bit of a scare before telling him a story. Awww.

6. Meltar
The Leader of the Inhumanoids, Metlarโs an imposing figure, his torso covered in scales and his weird looking hands. For some reason he and the rest of the Inhumanoids have these big red fangs which sometimes glow, but the real scary thing about his mouth is thereโs a pool of lava there, which he pulls his fireballs from before flinging them at his adversaries. The main thing keeping him this low on the list is in the episode Primal Passions. Metlar falls in love with the Statue of Liberty and brings her to life, turning her into the typical sitcom nagging wife who forces Metlar to do sit-ups because he looks like heโs gained weight.

5. Langistoids
I had to guess on the name of this underground species as I couldnโt find a thing about them online. These weird creatures remind me a lot of Darkstormโs Mollusk totem in Visionaries, being able to roll up into their shells. Their skinny arms and dog-like faces sure donโt help their looks, but considering theyโre only the size of a human ruins their scare potential. Not to mention seeing them eat the โsurface foodโ theyโre addicted to – pizzas and burgers, which they eat with abandon along with their boxes and wrappers.

4. D’Compose
People are going to give me so much crap for putting DโCompose so far down the list, but bear with me. DโComposeโs powers of turning people into monstrous zombies is pretty scary, especially Sandra Stone, who he turned into a giant monster twice in the show. His exposed ribcage is pretty cool looking too, and of course heโs got Chris Lattaโs excellent voice. Too bad all he does is yell his own name with it and only locks someone in his ribcage once. Above all that, DโComposeโs scariest accomplishment is creating a monster further up this list.

3. Tendril
I was prepared to put Tendril way lower on this list since he just looks like a green drainclog you pull out of your shower, but then something happens in the episode Primal Passions. Just as Metlar falls in love with the Statue of Liberty, Tendril gets romantic as well. With a robot that looks just like him. Worse yet, we hear him speak in his gargly tones, saying to the robot, โHello! Talk to me, baby!โ and worst of all, โYeah, baby, letโs get down!โ Gah-ross!

2. Nightcrawler
I wasnโt quite sure to include Nightcrawler in the list as he isnโt an official Inhumanoid, but one of DโComposeโs undead creations. Originally a scientist by the of Dr. Herman Manglar and imprisoned with Senator Blackstone, he escaped in a breakout that took him through a swamp filled with toxic waste. He drowned in the stuff, but Blackstone returned later to obtain Manglarโs rotting skull before DโCompose resurrected him, turning him into a fusion of shredded technology and human remains. His skull-like face and bone whip arm, make him stand out even when next to Blackstoneโs freakish body armor.

1. Gagoyle
Last year, I wrote a list of the Top Ten Spookiest Cartoon Bad Guys, the number 2 spot was shared by DโCompose and Gagoyle, but honestly, Gagoyle deserves this spot all by himself. Thereโs nothing thatโs not horrific about this guy. The giant tooth-filled maw, the single eye, the exposed digestive system – itโs all nightmare fuel. Then you consider its introduction in the show, where it hatches from an egg and proceeds to devour its next-mates. Itโs not even something that happens off-screen, we see it pounce on one as soon as it pokes out of his shell, then rips the arm off another and eats it. Itโs frankly disgusting and I love it.
