I don’t think you can count The New Adventures Of He-Man. It was based on Mattel taking the original Masters Of The Universe idea and basically reversing things. Instead of magic with a hint of science it was now science with a hint of magic. Although I wouldn’t be surprised to learn the Highlander cartoon was a retooled concept.
I also wonder how much advertising of the movie and series played into creating kid versions of R properties. Ads for RoboCop shown during the family hour, for example, would just be a cyborg cop fighting crime. Ads for the Rambo movies is just Rambo fighting bad guys, probably with explosions but little to no death. (Again, family hour. Movie studios weren’t going to give up prime advertising space just because half the target audience couldn’t see the movie.) And Highlander is a big swordfight, which kids would find cool. The series however…well, it was better than Mortal Kombat: Defenders Of The Realm. How’s that for faint praise? The series didn’t work for me and I was never a die-hard Highlander fan.
Wanna see an animated Highlander done right and better? Watch the anime movie, Highlander: Search for Vengeance. Unlike Highlander: The Animated Series, Highlander: Search for Vengreance stayed true to most of the established themes of the franchise.
Judging from Spoony’s review that’s all it has.
Kortan was out of place, but at least it made sense for there to be such a villain in an action series. Remember the half-robot guy from the Free Willy series? Now THAT was just ridiculous.
