SSJ_levels

Super Saiya-Jin level 1
Physical Features- Hair turnes from black to blonde, increased muscle mass, green eyes, change of judgement occures.
Requirements- Pure Heart(supposedly, look at Vegeta),Powerlevel at LEAST 6,000,000.
SSJ Level 1 comes from a NEED, not a desire. It happens when rage, sadness, and/or sorrow is triggered. The first transformation is spontanious.
After the 1st transformation, most Saiya-Jins (in DBZ, ALL) can transform at will. SSJ level 1 increases strength, speed, hearing, vision, wits, and the thirst for fighting.
Who Achieved It?- Gokou, Vegeta, Gohan, Trunks, Goten, Brolli.

Ultimate Super Saiya-Jin Physical Features- Spikier hair, muscles massively increase, stronger but slower.
Requirements- Have to at least be SSJ 1.
Ultimate Super Saiya-Jin is the stage in between 1 and 2. It has some advantages, but a HUGE disadvantage. This level seems to be easy to achieve, because almost everyone transforms to this level. This level is achieved by training hard, it increases your strength, but all the bulky muscles make it hard to move, therefore making you slower. Also in this level, the person wears themselves out trying to power up. That is why Gokou and Gohan (after coming out of the Room of Space and Time (Hyperbolic Time Chamber) stay in SSJ for, so they don't wear themselves out.
Who Achieved It?- Vegeta Future Trunks, Gokou, Brolli.

Super Saiya-Jin Level 2
Physical Features- More triangular shaped hair, on MOST of them, one bang is hanging down (except for Veg.) Increase in all areas.
Requirements- Have to at least be SSJ 1.
Super Saiya-Jin 2 is considered one of the best stages, it too (like 1) is triggered by rage, sorrow, and/or sadness. In this stage, you can raise your power, but your speed or stamina has to go down. That is the good part about this stage, you waist basically no energy to do things. This stage, you don't look all buff, but you are stronger. And probably the most easily noticed thing is when a SSJ2 powers up, there is electricity around them. Gohan's aura is gold with the electricity, Vegeta's aura is blue with electricity. Gokou's is the same as Gohan's
Who Achieved It?- Gohan, Vegeta, Gokou, Gogeta(movie), Vegeto

Super Saiya-Jin Level 3
Physical Features- MAJOR CHANGES. Long hair down to butt, no eyebrows, increase in speed and strength.
Requirements- Be one powerful son of a *&^%!.
Super Saiya-Jin level 3. This is an alright stage, considering you only have 30 min to use it because the stage uses a lot of energy. Only one person attained this level, and it is none other than Gokou (not including the fused Gotenks). He attained it while being DEAD, and training with the Kaio's. This level helped Gokou against Buu, and in movies, against a couple of foes. Gokou reached all new heights with this level. It's sad when SSJ 3 Gokou is stronger than the fused SSJ 3 Gotenks
Who Achieved It?- Gokou, Gotenks

Super Saiya-Jin 4
Physical Features- Hair turnes back to black, Monkey hair grows, tail, red around the eyes w/black pupil
Requirements- Must have tail, must have transformed into Golden Ouzurro.
Super Saiya-Jin 4 is very interesting. Many people (including myself) think that SSJ 4 is the "Original" SSJ form. If you recall when Vegeta first said that Gokou was a SSJ (while fighting Recoom, Jeise, and Bata), the mental picture in Vegeta's head was a Golden Ouzurro. Well SSJ 4 is the "Compact" size of the Golden Ouzurro. SSJ 4 has many changes, for one, the hair is black, red around eyes, return of the tail, and monkey hair on them. Gokou got his tail back by one of the Kaio's or King Kai pulling it out with tweesers (some tell me from a ritual), Vegeta's returned through a device made by none other than..........Bulma.
Who Achieved It?- Gokou, Vegeta, Gogeta.
