The Origin of Stretch Armstrong (partially found action figure-licensed comic book; 1992)
Stretch Armstrong is an action figure introduced by Kenner in 1976. The figure could stretch up to four feet, and bend into different poses, then stretch and bend back into his original shape. Kenner stopped producing him in 1980, though a few attempts to reintroduce him have occurred since then.
From 1992-1997, Cap Toys relaunched Stretch Armstrong as a pliable superhero, with a variety of other aliases. Initially, this figure also came with a free comic book detailing his origin. As of February 2016, only the first and last pages have turned up online. Advertiser Scott Edwards shared them on his Pinterest page some time in 2015. From this scan, the comic appears to have ran at least eight pages total, and traced Stretch Armstrong's journey to find his estranged father. Aside from Stretch becoming part of a crimefighting team (none of whom, except for Stretch and his dog Fetch, actually received their own toys) before the story's end, the rest of the plot remains unknown.
Hasbro purchased Cap Toys in 1997, making them the current owners of the Stretch Armstrong trademark. They have also made a few attempts to translate the character into other media: An unreleased live-action movie, a short-lived comic exploring the worlds of different Hasbro-owned toys, a cartoon on Netflix. Details revealed about these projects - including some animatics and artwork - do not make it seem like any of them followed the plot of this comic.
