A mutation that creates a yinglet who is two perfectly mirrored halves of themself, merged down the middle?
Certainly possible.

They become a roving rogue-psyker hunting assassin?
Much less probable.
But I guess the existence of Beizel at least makes it a distant possibility.

Anyways, this is just another crossover reference image, where I drew the irritated lady Nkaanmykiunsuns, from the erotic game Teraurge (v3 never ever), as a yinglet.
