Hypnos: The Ultimate Enemy! was a 14" figure released in 1976 by Mattel as a foil to their baby-face character Pulsar: The Ultimate Man Of Adventure! It was a freakin' sweet toy and I loved that thing when I was a kid.
His body was transparent except for his head and his back. There was a switch on his side and when compressed it would shoot sparks off inside of his torso, and a spiral inside of his chest would start spinning around. It was a pretty cool action feature, and it worked! That thing used to hypnotize me all the time!
Anyway, I used a translucent DC Direct Martian Manhunter as the base, and it is really the perfect base for this character. The scale is slightly different than the DCUC buck I used for Pulsar, which works well because it gives Hypnos a size advantage over his nemesis, which seems fitting for an alien villain! His arms and legs were painted with transparent purple to retain their luminescence. I included an outdoors photo of him that really captures this effect. All of the straps on his chest and back were dremeled off, and his chest and stomach were clear coated with gloss Mod Podge. His back was painted with opaque paint, but I created a circular design in the center of it with transparent paint, so that if you shine a light through the circle and stare at his chest you will instantly be transported into a jungle of psychedelia the likes of which has not been seen since Alice fell through the looking glass and down the rabbit hole! Ha - not really but this technique does a good job of emulating the action feature of the original toy. I use a bendy clip-on LED light that I bought at the dollar store to use for this purpose. His helmet is from a CTVT Black Knight figure.
Thanks for checking it out! Aloha Mi Amigos!
