"Look at that delicious brain. Alright, I'll be your friend! Wait! My pets! Hold on!"
A demon with four brain-hungry snakes growing from her shoulders. It's said that Zahhak gains the knowledge of the person whose brains she eats, so she has a tendency to target intellectuals. They fear Zahhak more than other demons, and her name makes them shiver. Some Summoners receive great rewards from intellectuals for exterminating Zahhaks.
