|Behind the Scenes|
Au Tsum is a large, venerable adult hammerhead. Eywa granted Nok the ability to summon Au Tsum using Howling Pods. Whenever Nok smashed one with his Maul, Au Tsum would appear and crush whatever lay in his path.

Au Tsum was first seen in the western edge of Dusk Valley, where he lay sleeping. Lungoray awakened him by splashing a potion made from glow worms over him. The potion allowed Eywa to influence his actions, and he rampaged north, straight through the RDA base in the Hammerhead Graveyard.
- Au Tsum's name may be a reference to A' Tuin, the great turtle on which the Discworld is supported in the eponymous franchise.
- The creature's name may be a homophone of the Hebrew word עצום (Aa-tsum) meaning giant, enormous or huge.
