I have stumbled into a debate in my favorite MOTU/POP/NA facebook group Shadow Weaver's Realm. Apparently it's old news that Bravestarr was a second spin-off of He-Man, but I can't find any info anywhere online stating this.
The only thing I've been able to come up with is that Bravestarr evolved out of Filmation's Ghostbusters cartoon series: http://articles.latimes.com/1986-12-21/magazine/tm-3736_1_bravestarr-toy
According to this article, Tex Hex was developed for the Ghostbusters show, but Lou Scheimer liked him so much that he decided to develop an entire show around him - thus Bravestarr was born...
Does anybody have definitive information - or know where I could look to put this debate to rest, at least in my mind?
