The multiple-limbs thing goes back a long way. I remember, as a kid, obsessing over:
• Kary (aka Marilith) from Final Fantasy, and generally all D&D mariliths (plus Secret of Mana's Hexas)
• Goro and Kintaro from MK
• The two-headed snake enemies from FF2/4, to the point where I was trying to figure out how to make a costume
All of these were around when I was 11-14 or so. Other boys obsessed over pictures of naked women. I had … that.
Small private instance for a group of friends.
