Queen Chrysalis searched tirelessly for pony scientists and doctors to turn her into the perfect changeling, implementing copper tubes, valves and wiring way beyond the contemporary grasp of technology to enhance her natural hypnotic smoke and turn herself into the most deadly and efficient changeling to ever have lived.

Our queen is the most benign creature in existence and the wisest of all, always leading us to food and crushing those that would threaten us with an iron-hoof!
BOW DOWN TO OUR QUEEN!

I’ve been wanting to draw Chrissy for ages, you have no idea TwT
