It is possible for a Saiyan to partially manifest Super Saiyan power in their base form without actually turning into a Super Saiyan.
Concept and creation
The appearance of this ability is actually the result of an animation error during production. Originally, Goku was intended to actually turn into a Super Saiyan when fighting the Ginyu Force and Cell, as indicated by the trailer for "Warriors of the Dead". However, this was changed to have him fight in base form. As a result, they changed the hair color to black, yet left it in the Super Saiyan style and retained the golden aura.
The user powers up, gaining a golden aura and Super Saiyan-like hair without actually transforming into the state.
When aiding Gohan with the Father-Son Kamehameha in the manga, Goku appears with black Super Saiyan hair. In the anime, Goku uses this ability when confronting Frieza, Cell, King Cold and the Ginyu Force in Hell. He uses the power to defeat the Ginyu Force and prepares to fight Cell until Pikkon attacks and defeats Cell in a few hits.
Later, in Dragon Ball GT, Goku uses this power-up when starting his fight against Frieza and Cell in Hell. During the battle with Naturon Shenron, Goku briefly manifests his Super Saiyan aura in his base form while talking to Naturon before transforming to Super Saiyan 4.
In Dragon Ball Super: Broly, when finding he is outmatched by Broly when the two are in their base forms, Vegeta channels some of his Super Saiyan power prior to fully taking on the transformation - giving him a golden outline and allowing him to overwhelm Broly.
Video Game Appearances
Several cards featuring artwork of Goku using this power is featured in Dragon Ball Heroes. The card has the ability Super Saiyan Power! (超サイヤパワー！ Sūpā Saiya Pawā!), which makes it that, if Goku transforms into Super Saiyan on the second turn after a Kamehameha, his power is +2000, or +5000 if it is greatly successful, transforming him into Super Saiyan 2.
Goku appears with black Super Saiyan 2 hair on the cover of Dragon Ball Z: Extreme Butōden's demo version.
- In the colored version of the Dragon Ball Super manga, Goku and Vegeta were depicted with golden auras when at full power but low on energy and unable to transform against Infinite Zamasu and later Moro.
