Super Saiyan 2 (超スーパーサイヤ人じん２ツー, Sūpā Saiya-jin Tsū), initially referred to as Super Saiyan Fifth Grade (超サイヤ人第五段階, Sūpā Saiya-jin Dai-Go Dankai) at the time of its debut, though referred to as "Ascended Super Saiyan" in the Funimation dub only, is the direct successor to the first Super Saiyan transformation. It is very similar to the original form in appearance and attainment; however, the power output is far greater, as speed, strength, and energy output all drastically increase. The transformation debuts with Gohan in the manga and the anime during his showdown with Cell in the Cell Games (Cell himself achieving the form not long after).
