Boss enemy idea
mechanics
the primary mechanic is a light matching system
your goal to survive her pouncing you is to make sure you match how much light shes producing her neon lights will produce a set amount of light failure to atleast get close to this light level will have her running towards you with a rumble as she pounces the oc and rams her huge cock deep inside of her maxing out all her stats with a gameover screen of the futa sitting down somewhere [suggestion a throne or chair] breeding her as the mc is drolling from being broken
2ndary mechanic
Mr - x
or nemi
this perma chase mechanic would last to other levels with tunnels or open spaces with huge areas for her to be supported in her nemi chase is mainly because she can smell the mc and always knows where she is based on the smell of breedable
she will still leave your area to let the player continue because shes hunting you not fucking you her chase will have her hunting you thruout the area
[sub mechanic would be masterbaiting you could make it so players can masterbait to confuse her]
from resident evil
boss keeps chasing you thru her world
[note this is based off the futa idea think miss d from re village shes that huge and bulky but her skins pure black with neon tatto's]
main level design shes seen on
basicly a map with pitch black on one side its also near the surface but has windows like from a basement near the roof of this floor to provide the floor a range of light the futa boss will use to fool you
lore
the idea of why she cant see you inside this light range is mainly because shes like a bat just think her main sight line is anything outside that thin line of light matching the light puts you inside of her blind spot and in turn safe
first interaction idea
a room of a bunch of girls just panting filled with seed from her ravanging them when she sees the mc she stands up and teases the mc with her cock and then flicks it as she walks towards a door which leads to the arena where she will walk around in any time you see her you have around 10-15 secs to match the light {balancing required}
