Appearance
The epitome of pure power; the supreme being overall. In order to achieve this form, immortality must be wished from the Dragon Balls. After thousands of years of training and hundreds of Zenkai later, SS10 may only be achieved from channeling the power of a universal spirit bomb into the wielder, but only after Porunga and Shenron's powers have been given to the warrior. Before the wielder is about to be consumed by pure energy, he must be empowered by Blutz Waves. After Oozaru is about to metamorphisize, said warrior must funnel the power into a human-ape form. This form has the ability to destroy the universe 10 times over. If this form is sustained longer than 15 minutes, the universe would collapse on itself, creating a void of which there is no escape.
