Abroad and in syndication
The syndicated version of The Underdog Show consists of 62 half-hour episodes. The supporting segments differ from the show's original network run. The first 26 syndicated episodes feature Tennessee Tuxedo as a supporting segment (Tennessee Tuxedo originally aired as a separate show and also has its own syndicated adaptation). Thereafter, for most of the balance of the package, the middle segments include Go Go Gophers and Klondike Kat for three consecutive half-hours and Tennessee Tuxedo in the fourth. Commander McBragg is featured in the majority of episodes, replaced by three segments of The Sing-A-Long Family (in shows one-three, 28–30, and 55–57). The final two syndicated Underdog half-hours feature two one-shot cartoons that were originally part of an unsold pilot for a projected 1966 series, The Champion (Cauliflower Cabbie and Gene Hattree), with Commander McBragg appearing in show 61 and Go Go Gophers in show 62.
The syndicated series, as shown in the United States, is a potpourri of segments from previously aired versions of the show. Prior to a 1994 remaster, each episode included a "teaser" at the top of the show, asking viewers to stay tuned for a clip from "today's four-part story" (This originated from a 1969-1973 NBC Saturday morning rerun version of the show, though this bumper was also seen during CBS reruns in the preceding years.); however, outside of CBS-TV airings of the show, no more than two parts of the Underdog stories were ever shown in any half-hour program. There have also been different syndication packages bundled with both elements from Jay Ward's The Adventures of Rocky and Bullwinkle and Friends, and The Most Important Person short films. Prints of such would either be followed by a closing and credits or no credits at all. The closing (which showed the first portion of a variation of the Underdog theme showing a giant terrorizing the city with George S. Irving, the series narrator, saying, "Looks like this is the end! But don't miss our next Underdog Show!" in place of the theme music) followed by the end credits (re-edited from the cast credits for Underdog and Tennessee Tuxedo), originated from a 1969 repackaged syndicated series, Cartoon Cut-Ups, which originally featured Underdog, Tennessee Tuxedo, and Commander McBragg. As the Underdog, Rocky and Bullwinkle, and The Most Important Person segments are all now separately owned by different entities, the syndicated prints are no longer in distribution.
Most stories were split into 4 parts, but the first three were stand-alone stories:
Reruns of the show aired on Nickelodeon from 1992 to 1994, Cartoon Network from 1996 to 1999, Boomerang from 2002 to 2007, and on MeTV Toons since 2024.[5] However, during its broadcasting on Cartoon Network and Boomerang, two notable episodes, "The Molemen" and "A New Villain", were not included on the channels' schedule due to depicted dangerous elements subjected within the segments.
In 1995, Biggers, Stover, Covington, and Harris (with General Mills) negotiated a sale of their creations to Saturday Night Live producer Lorne Michaels' Broadway Video, who later sold the rights to Golden Books Family Entertainment in 1996. When Classic Media took over Golden Books in August 2001, it acquired the underlying rights to Underdog. In 2012, Classic Media was sold to DreamWorks Animation, and ultimately became the property of the series' current owners, Universal Television as a result of Comcast's acquisition of DreamWorks Animation in 2016. TV Guide ranked Underdog as number 23 on its "50 Greatest Cartoon Characters of All Time" list, IGN ranked it as number 74 on its Best 100 Animated Series list.
- "Safe Waif", the pilot, featured a rescue from a bank vault, but no villain. Underdog is shown causing major destruction while trying to help people.
- "March of the Monsters", the first appearance of Sweet Polly Purebred, has giant robots running amok.
- "Simon Says" is the first appearance of Simon Bar Sinister. "Simon says HOLD IT!" is the maniacal refrain, as Bar Sinister uses a weird camera to turn his victims into full-sized, two-dimensional photographs.
- "Tricky Trap by Tap Tap" is the epilogue to the multi-part story "From Hopeless to Helpless" featuring Riff Raff; this episode was created due to story arcs not airing in their proper order (parts 2 & 3 of a story arc were shown in one half-hour show, then part 4 of the previous arc and part 1 of the next arc in another half-hour show).
