The first post in a new Friday series. Chip in with your own candidates in the 'Comments' section.
Stinkor made his first appearance in 1985 as a villian in the "Masters of The Universe" toy line. The "Evil Master of Odors" had a distinct gimmick, which was that when you opened his packaging, the little bastard ACTUALLY SMELLED LIKE SHIT.
I don't know why anyone at Mattel ever thought this was a good idea, but Stinkor actually sold pretty well, and Moms even purchased me my own Stinkor action figure back when I was about 6 or 7. I don't know what I was expecting, but when I ripped open his plastic casing, I was assaulted by a wave of Stinkor's foul stench, and promptly buried him in the back yard.
Stinkor never made an appearance on the Masters of the Universe cartoon, although he had a solid origin story and ties to both The Sorceress and Skeletor. He was originally presented to producer Lou Scheimer for inclusion in the He-Man spin-off She-Ra, Princess of Power (as part of Hordak's Evil Horde), but was promptly dismissed as nothing but a "walking fart joke".
The Stinkor action figure was actually made from the same mold as Mer-Man, but with a different color scheme. His body armor was also recycled from an earlier figure known as Mekaneck.
Stinkor sucked. Fuck you, Stinkor.

While researching this post, I came accross the fact that Stinkor's stench was produced by manufacturers mixing PATCHOULI oil in with the plastic that made up his body. So Stinkor was a HIPPIE, too! Some toy collectors report that 25 years after his initial production, Stinkor still smells bad. Seriously.
