Description
Super Saiyan 4 is an advancement of the Super Saiyan and Golden Great Ape forms introduced in Dragon Ball GT.
As part of the Great Ape branch of Super Saiyan transformations, it is separate from the standard branch of Super Saiyan forms despite being named in similar number. A devastatingly powerful form, it gifts the Saiyan with primal power, though they retain a humanoid appearance.
This form gives the user the super strength and speed of a Great Ape, but with a calm, clever mind. But for others, it can make them very cold and aggressive. A user of this form loses some of their rationality.
In Dragon Ball SF, this form is achieved by Gohan after using a Blutz Wave amplifier created by Bulma, and later after mastering Golden Great Ape during training.
