Dragon Ball Goku Super Saiyan 2Super Saiyan 2 was a transformation form of the Saiyan in the Japanese anime Dragon Ball. According to Goku, it was "a Super Saiyan that surpassed the Super Saiyan." Goku had shown this form when he fought Vegeta in the Buu chapter. His strength could easily defeat the complete form of Sarroux.
Before the Shalu Chapter, Goku had already reached the limit of his Super Saiyan state when he came out of the mental time room. When Sarroux was playing, Goku's Super Saiyan was at full power, and his energy reserves were fixed. At that time, Gohan's transformation (not explicitly Super Saiyan II and not necessarily a traditional Super Saiyan) reached the state of lightning. That was Gohan's exclusive transformation mode when he broke through the limit of anger and potential. Not every Saiyan could achieve it. If there was no follow-up Buu chapter, Lightning Gohan might be the ultimate form of Gohan's full potential. However, in the Buu chapter, Goku displayed his Super Saiyan 2 form when fighting Vegeta.
The shapeshifters who had transformed into Super Saiyan 2 included Sun Gohan, Sun Wukong, Vegeta, Future Trakus, Kaliphra, Gaga, Kaiphra, etc. This form appeared many times in Dragon Ball Z, Dragon Ball MT, Dragon Ball Super comics and animations, and Dragon Ball Heroes, and derived many enhanced forms. The combat power of this state was twice the full power of the Super Saiyan, which was 100 times the normal state (from the Super Excitement Guide: Story). In essence, it was twice the power of the Super One in a short period of time. The total energy did not change, so the physical consumption was twice that of the Super One (according to Toriyama Akira). If he trained hard, he would be able to unleash the power of a Super Saiyan 3 (see "Trakus"). You must become a Super Saiyan or a Super Saiyan at full power before transforming.
