Another cartoon/toyline from the 80's that I dig. The creatures are Metlar, D'Compose and Tendril. The show was a little gory for it's time and only 13 episodes were made.
That was a problem with 80s cartoons in general. The toy lines were not as good as the TV show. Insufficient toy sales would lead to the show being canceled before much development happened.
Dinosaucers, Road Rovers, SWAT Kats, Extreme Dinosaurs, Mighty Ducks, Gargoyles, Barnyard Commandos , Biker Mice From Mars, and Mummies Alive while we’re at it.
Agreed, I would love to see these guys come back. I had read somewhere that there was a comic adaptation of the Inhumanoids in the works as part of a Hasbro shared universe but it felt apart. It seems that the title is too close to the Marvel Inhumans and something could not be worked out.
