Son Goku Super Saiyan 2

Super Saiyan 2 (超サイヤ人 ツー) 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. Gohan is the first person to attain the form in the manga, and he uses it while fighting against Cell in the Cell Games. Goku and Vegeta soon follow, with Goku learning it in the Other World and Vegeta learning it on Earth.
