The Umu Dabrutu is a group of demon/monsters created by Tiamat who represent chaos storm. These monsters have no specific form or anthropomorphic features from tablets or art however as pointed out by McBeath29 that in the Anzu legend, the Anzu is described as "bared his teeth like an Umu-demon30". Wiggerman defines them as "weather-beasts"31 and as being "Leonine monsters". They are not specifically associated with the 11 chaos-monsters however we can see their "spirit" associated with more developed and known monsters and demons. The Kassapu may utilize incantations to compel their manifestations at different targets or goals which involve unrest and chaos. They may be used in incantations to initiate change however can be considered highly unpredictable as they seem to be strongly align to be a daytime personification, the fierce sun or weather associated therein.
