From Toy Galaxy’s YouTube description: Inhumanoids was a 1986 cartoon and toy line created by Hasbro that lasted only a single season.
Unique because the title characters were the bad guys, the Inhumanoids, and not the good guys, the Earth Corps (bunch of nerds).
There was a line of large action figures and the stories in the cartoon were serialized so it had a lot going for it but not enough for it to break through the glut of ’80s properties.
From Toy Galaxy’s YouTube description: The Dungeons and Dragons cartoon hit the airwaves in 1983 riding the Satanic Panic wave from the Dungeons and Dragons Role-playing Game and only lasted a few seasons.
It was also not helped by the fractured marketing approach which had a toyline and other merchandise being released as Advanced Dungeons and Dragons with no action figures made of the characters from the cartoon.
Despite all that, it led in the ratings for it’s first 2 seasons and made a lasting impression on pop culture at large.
