|Super Saiyan 4|
|User(s)||Vegeta, Gogeta and Goku.|
Super Saiyan 4 (超サイヤ人フォー) is a Saiyan transformation present in the anime-only sequel Dragon Ball GT. This transformation is the ultimate combination of both the humanoid Super Saiyan and the Great Ape. The only way a Saiyan can attain Super Saiyan 4 is if he is already a Super Saiyan, can transform into a Golden Great Ape, and then regain conscious control over the form. After this form is attained once, it can be accessed at any point.
Appearance and powerEdit
In this form, the Saiyan's hair color differs, the same goes for the tail and the body is covered in red fur. A Saiyan in this form also possesses a shadow trim around the eyes and over the eyelids that varies in color, such as crimson. The hair is lengthened, but not nearly as long as a Super Saiyan 3's. The aura in this form loses the arcs of electricity and replaces it with sparkles and also becoming pure fire. In the case of the Fusion Dance warrior Gogeta, the coloration of the aforementioned features seemingly switch, as Gogeta's hair became a bright shade of red whereas his fur became a dark shade of brown and the trim around his eyes were black instead of red. The massive power and speed enhancements brought on by this form easily make it the strongest Super Saiyan form in the entire series.
For example, while Goku's Super Saiyan 3 form was almost unable to even faze Baby Vegeta, as soon as Goku transformed into a Super Saiyan 4, their roles in power became polar opposites, with Baby Vegeta being almost unable to hurt Goku at all. The users of this Super Saiyan transformation have signature techniques. For example, Goku develops an attack he calls "10x Kamehameha", as it is ten times (10x) stronger than the Super Kamehameha, while Vegeta, in his Super Saiyan 4 state, uses an attack he calls the "Final Shine Attack", which is a more powerful version of his Final Flash attack (although, Vegeta is first seen using this attack against Super 17 with one hand while in his first Super Saiyan form).
Unlike the Super Saiyan 3's strain due to the utilization in ki, this form does not require as much energy consumption as Super Saiyan 3's, allowing the user to stay in the state at a much longer duration. It also appears that the form makes the individual larger in height and muscularity. In scenes with Goku standing next to others such as Gohan, Goten and Trunks, Goku appears much taller and bulkier than all of them, even though in his normal state, he is relatively the same size. A highly debated subject, many fans believe the Super Saiyan 4 form to be the true form of the Original Super Saiyan, first spoke of by Vegeta in the Namek Saga. Vegeta states in his monologue, that "the Super Saiyan could only maintain his maximum power in the transformed state". Also, Elder Supreme Kai appears to know of the Super Saiyan 4 form, cementing the thought that Super Saiyan 4 has existed before Goku attained it, most probably by a previous Super Saiyan. The Super Saiyan 4 form even has enough power to break through a wish made with the Dragon Balls, as it turned Kid Goku into an adult again.
