Horns too big to hide under any kind of headwear
Big wings that don't fold down very tightly
Skin and hair colored so unnatually it's impossible to miss
Kitty ears and a kitty tail (you have to cut the ass of all your pants :/)
Scales going up your arms ending in sharp talons in place of fingernails
Sharp fangs so long that they peek out from your lips
furry thighs that end in cloven hooves (at least you don't have to buy shoes)
Long pointed ears that express way more emotion than you want them to
however many cybernetic parts it takes to overcome your human nature
Eyes that glow visibly at any lighting, through any material
Instead of skin, you have an iridescent segmented exoskeleton like a beetle
Gills cut all up the sides of your throat and torso that are stifling to hide
