Super Saiyan 6

Super Saiyan 6 is the sixth form of a Saiyan, achieving power level even beyond that of a Super Saiyan 5 and is a Super Saiyan of Super Saiyan 5.

Appearance
The appearance of the Super Saiyan 6 doesn't change much from a Super Saiyan 5, where instead of Gray Fur, the whole upper area is covered with Golden Fur, and the hair is turned into golden like that of a Super Saiyan 3, and shaded red area under the eyes similar to Super Saiyan 4.

Usage and power
To achieve this form, the user must have Super Saiyan 5 and having the energy from all Supreme Kais. Super Saiyan 6 eventually changes the personality of whoever uses it, into a cocky-over confident character, even Goku will turn that way. But when serious, the character changes into a wild personality, stating that the Super Saiyan 6 can not be defeated under any circumstances.
