This Saturday Morning Cartoon had a large following for several years and the show expanded from just Plastic Man to Plastic Man & Family including Baby Plas and added several other cartoons to the line up.
The origin of Plastic Man (voiced by Michael Bell) was never expressly stated on this series, but it was implied he was originally the small-time crook Patrick “Eel” O’Brian who reformed after he was left for dead by the mob and gained plastic stretch powers. Plastic Man, his girlfriend Penny (voiced by Melendy Britt), and his Polynesian sidekick Hula-Hula (voiced by Joe Baker) travel the world and are given their assignments from the Chief (also voiced by Melendy Britt) to stop any threat to the world. Plastic Man often retains his sense of humor even in dangerous situations, such as a giant octopus capturing Penny and Hula-Hula causing him to comment “What Scout troop did he belong to”?
Only Plastic Man villains Doctor Dome, Doctor Honctoff, and Carrot-Man came from the comics while every other villain was created for the series.
In early episodes Penny has a crush on Plastic Man, who chooses to ignore it as he himself has a crush on the dark-haired female Chief. However, in the second season Plastic Man reciprocates Penny’s crush on him and the two marry. The marriage produces a son (voiced by Clare Peck) who has the same powers as Plastic Man and spawns a lighter series of episodes featuring “Baby Plas” doing things such as saving his friends from neighborhood bullies.
Besides Plastic Man, Baby Plas, and the Plastic Family, the rest of the original lineup in the first season consists of:
Mighty Man and Yukk – The adventures of a tiny superhero (voiced by Peter Cullen) and his talking dog sidekick (voiced by Frank Welker) who wears a doghouse-helmet because he is so ugly that he can destroy practically anything just by looking at it. The two of them protect their city from various villains when called in by the unnamed Mayor (voiced by John Stephenson).
Fangface and Fangpuss – This second season of Fangface is about a reluctant werewolf (voiced by Frank Welker) and his baby cousin (also voiced by Frank Welker) who also turns into a werewolf and their adventures with Fangfaces friends Biff (voiced by Jerry Dexter), Kim (voiced by Susan Blu), and Puggsy (voiced by Bart Braverman).
Rickety Rocket – An artificially intelligent rocket (voiced by Al Fann) was created by a group of African-American kid geniuses consisting of Sunstroke (voiced by John Anthony Bailey), Splashdown (voiced by Johnny Brown), Cosmo (voiced by Bobby F. Ellerby), and Venus (voiced by Dee Timberlake). They solve mysteries in the future, in the vein of Speed Buggy.
By its second season, it was cut down to 90 minutes and everything except Plastic Man and Baby Plas replaced by three new segments in the lineup:
Dingbat and the Creeps
Thundarr the Barbarian
