City of the Plague God

When Mohammed Aziz and Sikander Aziz are trying to get the Flower of Immortality, they go to his domain to try and find Gilgamesh's boat to cross the Sea of Tiamat. He finds the brothers and threatens to eat them. They trick him into drinking a spicy sauce Mo had on him and he runs away, looking for water.


Humbaba is a giant with multiple digestive tracks on the outside of his body.


Humbaba is very territorial, violent, and dimwited.
