Mixcoatl was the father of 400 sons, collectively known as the Centzon Huitznahua, who ended up having their hearts eaten by Huitzilopochtli. The Centzon Huitznahua met their demise when they, and their sister Coyolxauhqui, after finding their mother Coatlicue pregnant, conspired to kill her. However, as they attacked she gave birth to a fully formed and armed Huitzilopochtli, who proceeded to kill his half-siblings. Mixcoatl was also related to 400 more gods, the Centzonmimixcoa, whom, together with his 3 brothers (all different from the ones named above) and their sister, he slew by ambush. Mixcoatl was also thought of as being the father of another important deity, Quetzalcoatl, the feathered serpent.
