Super Saiyan Goku

Super Saiyan Goku is Goku's Final Smash in Super Smash Flash 2. Tapping into the vast reserves of his power, Goku transforms into Super Saiyan (超サイヤ人, Sūpā Saiya-Jin) form. Goku's speed and strength are increased, and his hair and eye colors change. Super Saiyan Goku is one of the many Final Forms in the game, meaning that he is a totally different character who can wander around with more powerful attacks and is fully playable in the Final Form Brawl Mode.

Overview
Tales of the legendary Super Saiyan of old had been passed down for a thousand years, but even among the Saiya-Jin themselves, there was much doubt that such a form ever actually existed. However, in truth, any Saiya-Jin whose power level is above a certain threshold has the potential to become a Super Saiya-Jin. Only those with a calm, still heart are able to achieve the Super Saiya-Jin state; and even then, only by suffering an extreme sense of danger, anger, or sadness, can the power actually be awakened.

In Goku's case, witnessing Krillin's death at the hands of Frieza was the key to his transformation.

The energy involved in a Super Saiya-Jin transformation causes the Saiya-Jin's hair to stand on end and turn a golden color. The facial expression is sharpened, and the color of the irises turns to a bright emerald green. A Super-Saiya-Jin's power level is fifty times greater than that of his normal state. The massive energies involved cause the emotions to be stirred, making it difficult to remain calm. As a downside to this transformation, illnesses progress much more rapidly in this form, due to the body's increased metabolic activity.
