Trivia

 * This form was first introduced in Battle of Gods, and DBS Episode 9.
 * SSG is initially obtained through a ritual involving six righteous Saiyans or special divine training.
 * While in Version 1.0.9.4 the tooltip says that this form has a mastery bonus, it is false because mastery wasn't implemented to it. It will, however, be true when Version 1.1 comes out.
