Super Saiyan 5 is the fifth form of the Super Saiyan forms. To obtain it, the user must train extensively in meditation. The form overall focuses on dodging enemy attacks and exploiting their weaknesses, summoning bursts of strength when doing so. The light color of the fur and hair reflects the inner tranquility of the user.
Goku was able to achieve this form fairly easily, although it took Vegeta longer due to his more violent and impatient nature.
Through intense training in this form, the more powerful Super Saiyan 6 form can be reached.
