* AccidentallyCorrectWriting: The five part pilot “The M.A.S.S. Device” features at one point both GI Joe and COBRA attempting to collect “heavy water” from a sea floor pool. Surprisingly, such pools are [[https://en.m.wikipedia.org/wiki/Brine_pool real]], and contain hypersaline solutions which could reasonably be called heavy water. It seems unlikely the writers were aware of them.
* ExecutiveMeddling: A good example. When the Joes' toyline was created, there were originally no villains. Marvel asked about who they are supposed to be fighting. This is when Cobra was created. Because GI Joe was a more reality based war-themed toyline (as opposed to sci-fi or fantasy), Hasbro was very reluctant to create villain characters based on real life enemies of America in order to discourage children's play based on an iteration of CowboysAndIndians. So they created Cobra as a motley crew of terrorists with no stated nationality or politics other than wanting to rule the world.

* ThrowItIn: Snake Eyes' iconic all black figure came about because Hasbro needed to lower the tooling budget, so they just didn't paint the one ninja figure and named him Snake Eyes. [[EnsembleDarkhorse He very quickly became the most popular character of the toyline.]]
