>>11101624Tri-Klops is a maybe but I'll always imagine Beastman as one of Keldor's men during the era before Skeletor/He-Man, where the amulet he uses to control animals has turned the man into beast in a monkey's paw sort of way. Maybe Keldor himself even gave him the amulet, aware of its curse, and only keeps Beastman around as a middleman for the amulets power. I admit he could be the easiest one to make into an Earthling turned monster in this case.
Tri-Klops I've always imagined as just a member of the same warrior's guild that Fisto is a member of, so, that doesn't really conflict with him being of earth.
Evil-Lyn I can't see being a NASA scientist DEI hire who gets turned into a witch. It's the biggest stretch.
This reminds me the movie's comic adaptarion that kept a cut scene from the script where they discover the first Eternians came from Earth long ago...
