INHUMANOIDS -- When I was ten, this was my favorite mindfuck
INHUMANOIDS is one of those cartoons that is better than it appears at first. It was an attempt to launch even more toy-friendly cartoons in the late 80s (see also, GI JOE, She-Ra, He-Man, Rainbow Brite, Transformers, etc) but drew on Lovecraft for inspiration. It featured unstoppable evils from the bowels of the Earth and an anime-inspired design.
It was also heavily serialized, with an actual continuity running from episode to episode.
Check out this episode's synopsis:
In a reckless PR stunt, Senator Masterson and tabloid-TV journalist Hector Remirez, together with a menagerie of inept celebrity goons, mount a live televised "journey to the center of the Earth" aboard a fleet of dirigible vehicles, promising to rescue the Statue of Liberty from Metlar's abduction. Auger and company are content to let the inevitable televised chaos unfold, instead busying themselves with the marriage of their teammate, Derek Bright, to actress Stella Blaze, a fiery redhead recently rescued from the adoring clutches of Tendril... who also decides to crash the wedding. From his hospital bed, recovering Air Force pilot Brad Armbruster recounts how his plane was downed by the serpentine monster, Sslither, in the skies over Angkor Wat. Earth Corps consult the Redwoods for more information, learning the dark history of Sslither's dominion over the Inhumanoids before Metlar finally rebelled, managing to trap his slithery overlord within a shell of lava. Meanwhile, predictably, Masterson's subterranean team find themselves in over their heads, first being captured by stone warriors, then being made hostage to Blackthorne's ambitions. Earth Corps forms a reluctant alliance with Nightcrawler to combat the threat of Sslither and rescue Masterson's group just as Metlar arrives to pummel his hated ancient foe, who slithers away in defeat. Lady Liberty is later returned to the surface by Metlar's own accord when he finds himself less than enamored by her incessant nagging.
