The users of this transformation have powerful signature techniques. Trunks describes him as a "fully-powered Super Saiyan 4", and Gohan states that he has become stronger than Gohan thought was even possible, saying his power was indescribable. When Goku is given energy from Super Saiyan Gohan, Super Saiyan Goten, Super Saiyan Trunks, and Pan, his power further increases, gaining a red aura which occasionally flashes over his whole body, and becoming superior to a Blutz Wave amplified Golden Great Ape Baby. 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 massive power and speed enhancements brought on by this form easily make it the strongest Saiyan form in the GT series. The Super Saiyan 4 form draws the power of its users up to their absolute limit. 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 aura in this form loses the arcs of electricity and replaces it with sparkles (Gogeta only) and also once again shaped like a regular Super Saiyan's smooth aura, (this was not the case in several video games, like the Budokai and Xenoverse series, in which the form was depicted with a reddish (with a small yellowish glow) aura with sparks of bio-electricity, thus, due to the red aura, this makes Goku, Vegeta, and Gogeta playable as Ultra-full power Saiyan 4s from the start). The hair is lengthened, but not as long as its "predecessor", Super Saiyan 3's.

A Saiyan in this form also possesses a shadow trim around their eyes and over the eyelids that varies in color, such as crimson.

In this form, the Saiyan's hair color differs, the same goes for the tail and the body is covered in red fur. Vegeta's Super Saiyan 4 form seen for the first (and only) time
