Super Saiyan Goku

Super Saiyan Goku, previously referred to as Super Saiyan, was initially 's Final Smash in Super Smash Flash 2 prior to Beta 1.2, where it was replaced with Meteor Combination.

Overview
When performed, Goku would cover his face with both arms and gather energy before transforming into his Super Saiyan form, in which his hair becomes straight and yellow and his eyes become green. Upon transformation, he would throw his arms to either side and yell as a great yellow explosion in the shape of a flame surrounded him, dealing 18% damage and moderate knockback to opponents that made contact with it. Super Saiyan Goku was one of the many "Final Forms" in the game at the time of his inclusion, meaning that he was a much different character who has faster and more powerful attacks than his normal form.

Super Saiyan Goku was one of the most powerful Final Forms in the game. His attacks relied more on brute power in both damage and knockback, most of his attacks had little to no startup or ending lag, and he had strong knockback resistance to most attacks, as only some smash attacks and special moves caused him to flinch. These traits, along with his abilities to jump and float infinitely, made it very difficult to KO him.

Moveset
The following moveset list details the properties of Super Saiyan Goku's attacks in version 0.9.1.1982 of the demo, the most recent revision it was included in.

Origin
This form originated in the manga series . The transformation was first referred through numerous times during the Saiyan and Freeza sagas and finally made its appearance in Chapter 317 of the manga titled, Life or Death. Goku was the first person ever shown on the manga to achieve it after witnessing his best friend Krillin's death at the hands of the villain Frieza, using this transformation to ultimately defeat the latter.

The transformation causes Goku's hair to stand on end and turn a golden color. His facial expression becomes sharpened, and the color of his irises turns to a bright emerald green. As a Super Saiyan, Goku's power level is 50 times greater than that of his normal form. Initially, the massive energies involved cause Goku's emotions to be stirred, making it difficult to remain calm. As a pure heart Saiyan, Goku becomes ruthless and overcome with rage. This is first demonstrated when Goku went from a calm, collected fighter to becoming a vengeful warrior, hellbent on avenging his fallen friend, Krillin, even at his own peril. With constant training, Goku eventually managed to control his emotions during the transformation and also achieve mightier forms of the transformation, like the Super Saiyan 3, which increases his power level 400 times greater than his normal form. Super Saiyan 2 and 3 cost too much energy to be maintained, so Goku often uses Super Saiyan God forms instead to enhance Super Saiyan power, which appear in Dragon Ball Super.
