A form of [[Super Saiyan]] that appears in the anime-only [[Dragon Ball GT]]. Born from gaining control over the [[Golden Oozaru]] form, its main features are red fur covering the torso, longer hair, and red lining around the eyes. [[Son Goku]] is the first to achieve this form, followed by [[Vegeta]] and their fusion, [[Gogeta]] (whose Super Saiyan 4 form is different from his fusees, since his hair turns [[red hair|red]] and his body gains brown fur instead).
