Four Sacred Beasts

The Four Sacred Beasts is the title given to the four, immensely powerful aliens who's powers were acknowledged by the gods themselves. In order to prevent their extreme energies and abilities being taken advantage of by evil in the universe, The Choshin elevated them to god status and brought them to otherworld where their desires for fighting and combat would be forever sated. They were originally meant to be five, but the fifth beast, Sun Wukong, The Monkey King, refused the offer of the gods and stayed in the physical universe as a mortal being who later became the ancestor of the saiyans.
