The New Adventures of He-Man is an animated series which ran in syndication in the fall of 1990 while Mattel released the toy line He-Man, an update of their Masters of the Universe line. But to get to that point, there were a lot of versions (and a lot of He-Ro's) before He-Man put on pants and pulled his hair back into a cool 90's ponytail. The New Adventures of He-Man evolved from many other versions, shaped by Filmation going out of business.
