I can actually answer that pretty specifically.
I always enjoyed TFing, I used to record any I found on TV with VHS blank tapes, but it was about 8 or so years ago that a online friend of mine showed me a clip from a show made by the same crew who made Totally Spies called "Team Galaxy" and in one particular episode, the hot girl of the group gets turned into what is best described as a mutant, you can see for yourself here https://youtu.be/2ZHg2apE89g?t=848
ever since then i've found a fascination in blending the unordinary elements of a mutative form while maintaing as much of their human shape as possible to create a kind of morbid beauty
"morbid beauty" i too find beauty in things most find scary
Mileena - mortal kombat
the xenomorph and xenomorph queen - Alens
yeah, I cant say I myself find beauty in either of those (though I do like sexy parodies/homages of the Xenomorphs) but its nice that we share the same kind of appreciation for finding some beauty in things that put others on edge
