Saiyanism

Saiyanism is the worship of Omota, the Saiyan God of War. It was widely used among all Saiyans, but started decreasing in numbers after Saiyans started evolving, and once the Original Super Saiyan destroyed, the Saiyans mostly abandoned the religion.

It was worshiped by the ancient commonly.

Types of Worship
When the Saiyans worshiped, they generally didn't have chapels, and churches etc.. They had fountains of energy, where the Saiyans would donate some of their energy now and then to Omota, the god. Some religious Saiyans would bow around the fountain.

The religion was abandoned around 220 Before Age, after Planet Saiyan was destroyed and the Saiyans migrated to Planet Plant.
