Did You Know?


Hasbro decided to end the toy line during the first season, but allowed the show to continue as long as commercials for their other properties could be shown. This gave the writers much more liberty to create original stories. See more »

Four scientists in power armor battle monsters from beneath the Earth!
7 August 2002 | by mathewignashSee all my reviews

Four scientists, Auger, Bright, Armstrong and Herc, collectively called Earth Corps are called in when three giant ancient monsters called the Inhumanoids are accidentally set free by man's exploration. Earth Corps teams up with the mysterious Redwood men and Granite people to recapture this threat before the three can take over the planet. They explore the sub-world, save the planet's core, and generally fight evil. The also come up against power-hungry business men, mad Russian military leaders, creatures from the sub-world and even save the Statue of Liberty from having to marry an Inhumanoid when she comes to life and is wooed by the evil Metlar.

Based on the Hasbro toy line of the same name, and turned into a cartoon by the same people who did GI Joe and the Transformers (you'll recognize many familiar voices).

This series was teamed up in small segments with shows like Gem and the Holograms, Bigfoot and the Muscle Machines and Robotix and broadcast on Sunday mornings in 1986. All the small segments were tied together into longer shows for video release only on Beta for many years, but recently it made it's way to VHS and DVD.
