| Who |
Why/When |
| Super Saiyan (SSJ) |
| Goku |
After Goku had hit Frieza with a huge Genki Dama, he and his friends celebrated. Then Goku realized that Frieza had survived, and shot Piccolo. Frieza then raised Krillin into the air and imploded him. This pissed Goku off, because he didn't stop the evil beast, and he turned into a Super Saiyan! |
| Vegeta |
Vegeta, being of royal saiyan blood, thought that he should have became the Super Saiyan of legend. He trained long and hard, but couldn't reach his goal. This made Vegeta very angry, and turned him into a Super Saiyan. |
| Gohan |
Gohan was training with his father, Goku, in the Room of Spirit and Time. He realized that he had let down his friends during battles, and wouldn't be able to help in the fight with Cell, unless he turned Super Saiyan. He then turned into an awesome Super Saiyan. |
| Future Trunks |
Future Trunks was the second Super Saiyan when he first appeared. He achieved this level in his own time. Gohan, the only remaining Z fighter, had knocked out Trunks, and went to take on the two Androids. Gohan was killed, and when Trunks found him, his anger made him a Super Saiyan. |
| Chibi Trunks |
Chibi Trunks didn't have to do much to achieve Super Saiyan...when he had gained enough power, he went Super Saiyan to the suprise of Vegeta. |
| Goten |
Much like Chibi Trunks, Goten could go Super Saiyan when he had enough power. This suprised Gohan. |
| Gotenks |
Gotenks was in a sence "born" with the Super Saiyan ability. He was made when Goten and Trunks were SSJ, so he was born SSJ |
| Ultimate Super Saiyan (USSJ) |
| Future Trunks |
Future Trunks had achieved this level by training in the Room of Spirit and Time. He didn't learn the limitations of this level until he faught Perfect Cell. |
| Goku |
Goku could achieve this level, but he refused to use it because he knew the limitations. He achieved this level while in the Room of Spirit and Time with Gohan. |
| Vegeta |
Vegeta achieved this level, but not to the extent that Goku and Trunks did. Vegeta's muscle mass was increased, but not to the extent that his speed suffered too much unlike Goku and Trunks, who's speed greatly diminished. |
| Super Saiyan 2 (SSJ2) |
| Gohan |
Gohan had first achieved this level in the Room of Spirit and Time, but he had it for only about 1 second. Then, while fighting Cell, Cell pissed him off by destroying Android 16, and releasing Cell Jr.'s to beat all his friends. This made Gohan angry enough to gain SSJ2 and hold it. |
| Goku |
Goku reached this level while training in the after-life. He trained and battled with his ally and opponent Piku-han, and faught in the after life tournament with it resulting in a tie. So Goku gained enough to go Super Saiyan 2. |
| Vegeta |
Vegeta, actually achieve this level by cheating, because he had to turn into Majin Vegeta to get this level. He wanted to beat Goku, and so he went turned into a Majin slave, and got enough anger to go Super Saiyan 2. |
| Gogeta |
Gogeta was "born" with the ability to go Super Saiyan 2. When Goku and Vegeta fused together, they were both SSJ2, so Gogeta was born SSJ2. |
| Vegetto |
Vegetto, much like Gogeta, was "born" with the ability to go Super Saiyan 2. When Goku and Vegeta fused with the portoria earings, Vegetto was a regular saiyan/fusion. Then when Vegetto powered up to SSJ2. |
| Super Saiyan 3 (SSJ3) |
| Goku |
Goku, just like SSJ2, had reached this level in the afterlife while training with Piku-han. He used it on Buu, but couldn't reach full power, and this level made him go back to the after-life quicker. |
| Gotenks |
Gotenks gained SSJ3 while training with Piccolo in the Room of Spirit and Time, while training to beat Buu. |
| Super Saiyan 4 (SSJ4) |
| Goku |
While fighting Bebi Vegeta, Chibi Goku was getting a whoopin. He was knocked almost unconcious, and then looked at the full Earth. At that point, Goku changed into the Golden Oozaro. He was a beast, and couldn't be controled. He then powered up in the Golden Oozaro state, and turned into SSJ4 Goku. |
| Vegeta |
Bulma, his wife developed a Brute Ray, a machine that would give Vegeta the ability to go Golden Oozaro. So in a sense, Vegeta cheated. |
| Gogeta |
Gogeta achieved this state by Goku and Vegeta, both in thier SSJ4 state fused together to beat the evil Li shenron. Unfortunatly, because he was so powerful, the fusion didn't last the usual half hour, it went for about 15 to 20 minutes. |
