Underdog was a animated cartoon series that ran from October 3, 1964 to 1973 for 124 epsiodes. The hero Underdog was by day "Shoe Shine Boy" who when trouble appeared ducked into a phone booth and with the help of a mysterious "energy pill" which he keeps in secret compartment ring changes into Underdog who wears a blue cape with a red suit with a large "U". Among his powers are a super calculating brain; cosmic/X ray eyes and flying at the speed of light. A running gag is that "Underdog" girlfriend reporter "Sweet Polly Purebread" is abducted by villians before Underdog comes to rescue her. Villians included:
- Simeon Bar Sinister with his henchman Cad Lackey. Sinister is a sterotype mad evil scientist. In one epsiode he shrinks everyone in the city down to a few inches in height so he can "tower"over them!
- Riff Raff a 1930's type gangster with a wolf's face-a spoof of actor George Raft
- In one epsiode to save Sweet Polly Purebread from having to milk stolen earth cows for the cat planet Felina Underdog has to fight a giant cat bully Named Overcat who is bigger than he is! (In the live action movie Underdog rescues a cat from a building fire and then asks the cat not to tell anyone about it-he's got his reputation to uphold!}
In 2007 a live action movie was made based on the old cartoon series-can Underdog save his dog girlfriend Sweet Polly Purebread and his city humans as well from Simon Bar Sinister evil plan to make everyone obey him?
