Inhumanoids was a 13-episode Western Animation show by Sunbow Entertainment that aired in 1986. Like most 80's cartoons, it was based on an accompanying toyline, which was made by Hasbro.The main story focuses on a group of scientists called the Earth Corps. An enormous monster, called D'Compose, is discovered encased in amber in the Big Sur. By taking him out, they don't realize that they have unleashed evil on their world. Following that, many more discoveries of grotesque monsters happen. Tendril and D'Compose are two of those eldritch abominations. With the help of The Redwoods, they try to put down the monsters again.The show in its day had a lot of Family-Unfriendly Violence and remains a great source of scares. More importantly, it was an unusual kids' show for its use of good subplots, strong pacing and suspense.
Achilles' Heel: Metlar can be paralyzed by magnetic fields. D'Compose can be burnt by sunlight, which also returns his undead minions to normal.
A.I. Is a Crapshoot: Cypher, a linguistic computer is intended to communicate with Tendril and instead breaks him out, and then frees Metlar.
Ancient Astronauts: Metlar erected the Pyramids of Egypt as monuments to Sslither, as well as creating huge statues in China in his honor that became the inspiration for dragons. Eventually, he rebelled and sealed Sslither away in his favorite temple in Burma, a temple that Metlar built for him.
Animesque: Coincidentally, the animation style of Inhumanoids has much in common with 80's anime, compared to most other cartoons made in USA at the time.
Call Back: In episode 11, after Metlar finishes animating the Statue of Liberty as his fiancée, she complains that she wants a television. In episode 12, she spends most of the episode watching it while nagging at Metlar. In episode 13, all three Inhumanoids are depicted watching the same television.
Came Back Wrong: Dr. Mangler drowns in toxic waste, and is Stripped to the Bone by it. One of his minions brings his skeleton to D'Compose to resurrect him. The resulting abomination, who dubs himself Nightcrawler, is enough to freak out D'Compose himself.
Convection Schmonvection: Many characters end up walking harmlessly past lava, though admittedly the Earth Corps are always in their Powered Armor when they do so and Metlar is explicitly a being of living metal.
Creepy Good: The Mutores, despite being the good guys, are definitely monstrous. The Redwoods, in particular, you would mistake for evil until they start talking.
The Chick: Johnathan M. "Liquidator" Slattery (He is the emotional, instictive one, who talks about the "vibes" he gets from certain places)
Sixth Ranger: Tank (a renegade Soviet scientist who gets his tank rebuilt into armor) and Sabre Jet (a crashed jet pilot who gets cybernetic limbs built from his plane)
Give Geeks a Chance: Stella Blaze cartainly did when Derek saved her from Tendril. They later do a "Mr. Foam" commercial as Dr. Derek and Mrs. Stella Bright.
Green Rocks: Galvacite, a boulder that produces super-charged magnetic fields that can power up Magnokor... or induce a personality inversion for all metallic lifeforms... or cause the Van Allen Belt to destabilise and peel away, causing Earth to be fried by the full force of solar radiation.
Henpecked Husband: Metlar becomes this after falling in love with and animating the Statue of Liberty. It gets to the point where not only does she work him worse than his former slave-master Sslither did, he's happy to de-animate her and put her back on her pedestal off-screen because he's just that sick of her nagging.
Informed Attribute: Auger is introduced as an archaeologist. We never see him take any notice of the amazing archaeological finds like the medieval ruins in Skelweb.
Kaiju: The Inhumanoids, despite being smaller than regular Kaiju, and being intelligent and able to talk.
Love Potion: Episode 11, "Primal Passions", is about Earth Corps accidentally applying this to the Inhumanoids. D'Compose falls in love with Sandra Shore and tracks her down to turn her once again into an undead monster, Tendril falls in love with a robotic copy of himself being used for a movie, and Metlar falls in love with the Statue of Liberty!
Painful Transformation: Felt by Sandra Shore after D-Compose touched her cheek. You can hear her bones growing all throughout the transformation. Other transformed victims of D'Compose are implied to get the same.
Personality Swap: Magnokor and Metlar switched alignment after the former boosted their magnetic powers through a boulder of galvacite to finally defeat their arch-enemy.
Sleazy Politician: Senator Masterson. Every other problem the heroes encounter stems back from him. In episode one he's cutting their funding because he's friends with Blackthorn Shore. By the end of the series, he's outright allied with the Inhumanoids themselves to get elected as President.
Standard Female Grab Area: Averted. Sandra Shore is grabbed by her brother's security goons and manages to fight them off even after one of them has made contact with her forearm.
Too Dumb to Live: Blackthorne, really; why would you free Tendril in the first place? To confirm that Metlar lives? Okay, but... just what in the world would you want to enslave him for in the first place? Just what is that supposed to do that will benefit you? Then you make — and break — an alliance with Nightcrawler & D'Compose, and then you run off and reawaken Sslither.
Senator Masterson really isn't that much better.
Ungrateful Bastard: Blackthorne cries out for the Earth Corps to save him from Tendril in one episode. When they do, he shouts, "Thanks, SUCKERS!" and runs off.
Was Once a Man: Herman Manglar dies horribly, and is brought back as the hideous undead monstrosity Nightcrawler. He's delighted with his new condition.
D'Compose: It is hideous!
Nightcrawler: And I trust you will make me even more so.
Weaponized Landmark: One of the animated-statue guardians of Metlar's lair appears to be the Colossus of Rhodes. In a later episode, Metlar animates the Statue of Liberty. Subverted, as he marries her rather than uses her as a weapon.
What Happened to the Mouse?: Severing Tendril's tentacles caused their pieces to grow into new Tendril creatures, yet what became of the umpteen Tendril-clones spawned in this manner was rarely addressed.
Obviously they get re-absorbed by the main Tendril or they die off-screen like uprooted plants. In the Marvel Comics, Metlar tells Tendril that his clones will no longer be necessary, and then Tendril causes them to decay away.
What Have I Done: Bringing D'Compose to San Francisco was truly a big mistake...
D'Compose himself falls into this as well; when he reanimate's Dr. Mangler's remains into the hideous Nightcrawler, he backs away in fear, muttering "What have I wrought?"
When Trees Attack: The Redwoods are sentient trees that give assistance to the heroes every so often.
Tendril, being a plant-based Inhumanoid, is a hostile version.
Your Size May Vary: The flaw this show is best known for is the size of the giant monsters changing between episodes or even frames. In one episode they look about 20-30 feet tall and can fit indoors; in another, Metlar is just as tall as the Statue of Liberty.
