Tūmatauenga (Tū of the angry face) is the primary god (atua) of war and human activities such as hunting, food cultivation, fishing, and cooking in Māori mythology. In creation stories, Tū suggests to kill his parents to allow light into the world. After they are instead separated, he wars with his brothers and becomes the origin of humanity's activities, and the reasons for their behaviour when interacting with the creations of his brothers.
