Here's the last component from 1978's Tarzan & The Super 7 anthology series.
Super Stretch & Micro Woman were a husband & wife team of heroes, the second such coupling on the show, along with Manta & Moray. The reason you won't see their adventures on DVD any time soon is largely because their powers are derivative of other heroes. In Micro Woman's case, she's a female version of DC's Silver Age Atom, who had his own short-lived feature for Filmation & CBS 11 years earlier. Super Stretch (Ty Henderson, ex-Space Academy) was simply an African-American variation on Plastic Man and/or Mr. Fantastic of the Fantastic Four, the latter of whom was back on the air that same season, over on NBC, while Plas would come along the following year on ABC.
Palitoy uploaded this sample, which has our married crimebusters taking on their evil counterparts, totally opposite in powers, from another dimension. This is the concluding portion of that story.....
The presence of the couple's pet dog, Trouble, as their sidekick, recalls Inch High using a dog as a sidekick 5 years prior, so there's another issue.
