Visionaries: Knights of the Magical Light was originally a range of action figures from Hasbro, released in 1987. This action figure range was promoted by two different media, telling the stories of the characters. The better known of the two was a half hour animated television seriesmade by Sunbow Productions in the same year, but there was also a comic book series issued by Star Comics.
The toyline was not a big success, which led to both the series and the comic being cancelled after a very short run. The comic lasted only 6 issues, and was cancelled halfway through a four-part storyline. The animated series lasted one season of 13 episodes, and was not picked up for a second, possibly because all Sunbow cartoons came to an end after The Transformers season 4 three-parter ("The Rebirth") and G.I. Joe: The Movie, when Sunbow lost its contract and did not get it renewed.
Visionaries is the only Hasbro property to be produced by Sunbow on their own, without the aid of Marvel Productions. Sunbow also used TMS Entertainment, in Japan for the overseas animation work for this show, which had previously worked on Dokonjō Gaeru (Original).
