Anime

Note: Moderators had taken down the stacks before, since it was not wholly information based. I will post this as a note as to why such series are essential in order to defend them all as a blanket statement.
Most of the series featured have some sort of significance in terms of first best or darkest for their era which can be categorized by decennium or part of a decennium (early, middle, late). These are mixed around in order in order to give those who subscribed to list a challenge. While I could give an individual breakdown, I think some research is better left up to those who have subscribed to the stacks, since this allows for additional cultural insight into what was popular in Japan at the time, which is sometimes disconnected from the United States, as well as the rest of North America and Europe in many ways. For example, the Crayon Shin-Chan that aired in the United States and Canada is different to the one that aired in Europe, is different to the one that aired in Japan. By recommending to seek out Japanese versions of series, it grows understanding. I am not the first one to have thought of this. In the United States, there used to be a channel called ImaginAsian TV which had the same purpose of informing people about Japanese popular culture through anime. The San Francisco and San Diego PBS stations did the same thing and NHK World Japan carries this on through series like Little Charo and previously Maiko-san Chi no Makanai-san.
I think it is agreed upon that retro is a niche, but with handicaps on subject matter like availability.

Good luck finding this one in English. I was only able to find Episode 1 and some parts of Episode 2.
P.S: Microman was the line that gave birth to Transformers, but did not receive an anime until later.

Technically all of the Yuusha series are based off of scrapped Transformers concepts which were then given their own series and range.

This spinoff is fully subtitled, while the main series (Kinnikuman [1979 for future reference...]) only has 104 episodes finished. That said, there was a fully subtitled series that has sadly been lost. It might be worth checking old AnimeZen links which are still operating (they did a poor job at taking down the site, but at least some otherwise raw-only anime are able to be found).

TV, 1987,

Technically all of Machine Robo are spinoffs of GoBots, but the original Challenge of the GoBots is not listed on MAL.
