The user also loses his eyebrows completely, revealing a prominent brow ridge. Muscle tone is more defined, and the user's aura extends outward, so does the sparks of electricity.
Battling Baby Edit
Goku transformed into this form in Dragon Ball GT to combat Baby, and he realizes that he is not strong enough to combat Baby as a Super Saiyan, and ascends to Super Saiyan 3, although it doesn't work. Because Goku had been wished into a child, he could only maintain the form for about a minute until de-transforming. He later transformed again after Old Kai restored his tail. Although, he could maintain the form for about four more minutes than last time, although the latter is beaten again. Goku later ascends to Super Saiyan 4 and defeats Baby, and discontinues the form after it is outclassed by Super Saiyan 4.
