I think the problem is that this is NOT Filmations masters of the universe, It Mattels.
The original box art of Panthor shows a deranged wild purple cat, Nothing about that art says 'Panther'. It was Filmations streamlining (dumbing down) and literal interpretation that most people have an issue with.
So the designers at Mattel wanted a Cat steed for Skeletor,they looked at BC and went 'That'll do' they covered it in the fluff, made the armor Green, Chose a name that implied a different species (and one that the obligatory 'O' could be dropped into, to make it more Alien) and pumped it out... voila!
The Vintage Panthor is just the Big Jim Cat covered in purple velvet fluff. when we were kids that was enough, but as an adult -IMO- I care more about sculpt,Detail and paint apps than I do about a Gimmick!
The vintage art department looked at the Toy and thought 'Well its not a 'panther',Its a 'panthor' (it also looks like a Tiger shape) so they commissioned the box art to depict a Purple Tiger , they made it look ferocious,feral and hulking.
and THATS Panthor, hes not a Panther, Hes a member of the Purple Panthor tribe! Mortal enemies of the Green Tiger Tribe!
Thanks again 4H for following the Edict that these toys are based on the Vintage MATTEL concept!
