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,strength and power 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. His transformation deals heavy knockback and 18% damage.

Legend of the Super Saiyan
Tales of the legendary Super Saiyan of old had been passed down for a thousand years, but even among the Saiyans themselves, there was much doubt that such a form ever actually existed. However, in truth, any Saiyan whose power level is above a certain threshold has the potential to become a Super Saiyan. Only those with a calm, still heart (like Goku) are able to turn into a Super Saiyan; 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 Saiyan transformation causes the Saiyan'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 Saiyan's power level is 100 times greater than that of his normal form. The massive energies involved cause the emotions to be stirred, making it difficult to remain calm. The transformation has a noticeable effect on the Saiyan's personality. Any Saiyan that has a pure heart initially becomes ruthless and overcome with rage, and any Saiyan that was already ruthless to begin with has his ruthlessness amplified. This is first demonstrated when Goku turned Super Saiyan, when he went from a calm, collected fighter to becoming a vengeful warrior, hellbent on avenging his fallen friend, Krillin, even at his own peril.
