Super Saiyan 2

Super Saiyan 2 (超サイヤ人 ツー, Sūpā Saiya-jin Tsū), initially known only as Super Saiyan Fifth Grade, 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 the anime, and he uses it while fighting against Cell in the Cell Games. Goku, Vegeta and Future Trunks soon follow, with Goku training to achieve it in the Other World and both Vegeta and Future Trunks training on Earth.
