A lora focused on cybernetics, androids and robot. I manually tagged it to hopefully get a consistent and accurate prompting.
It works like this:

main: robotic body, robotic face, human skin, human face (these determine whether the body is organic or robotic and whether the face is too)
cybernetics (add "cybernetic" to any body part; also use these for fully robotic limbs: there are no "robotic ..." tags): cybernetic legs, cybernetic arms, cybernetic waist, cybernetic eye, cybernetic skin, cybernetic face, cybernetic head, cybernetic hair, cybernetic torso, cybernetic tattoos, cybernetic collar, cybernetic neck, cybernetic jaw, cybernetic armor, cybernetic ??????, cybernetic ?????, cybernetic mermaid tail, cybernetic dress

skin:
"[color] metal skin" - typical android body material; white is most common

"metal skin" - without color should produce a basic metallic material, like the atomic heart twins for example

"chrome skin" - shynier than metal
"banded metal skin" - should produce a metal skin like colossus from the x-men

"cybernetic skin" - metallic lines (and joints?) in the skin like with typical androids

"latex skin"

"transparent skin, glass skin" - transparent skin with possibly visible cybernetics underneath; use with "exposed cybernetics"

other tags:

"exposed cybernetics" - more rough look, black cybernetic parts not covered by skin or metal, exposed tubes and machinery; can be combined with "broken body, damaged body"

"broken body, damaged body" - damaged skin, damaged metal parts, exposed cybernetics
"[color] glowing cybernetics" - glowing lines, dots or parts on/between the cybernetics; also used for fully robotic bodies
"glowing waist", "glowing eyes" - produces locally glowing parts
"amputated arms, amputated legs" - robotic/cybernetic arms taken off

"metal breasts" - distinct breasts out of metal

"cables" - free hanging cables, hooked up to cables out of frame, exposed cables

"cybernetic demon, demon, demonic"

"cat ears, dog ears, animal ears"

"latex mask"
