Who perform it: Goku (DBZ Movie 4) & Brolly (DBZ Movies 8)
-Super Saiyan:
This is something only Saiyan or human/Saiyan hybrids can accomplish
(example: Gohan, Goten and Trunks). When a Saiyan is in the Super Saiyan state, their hair turns a blond color, their eyes turn turquoise and they are usually surrounded by a golden energy. The state of Super Saiyan is attained by accomplished by attaining several requirements. The Saiyan must have a quiet, pure and calm heart. The Saiyan must also have a
certain amount of power. The final requirement is extreme rage and lust for battle. This is why
it was so difficult for Goku to attain SSJ, because he's not normally an angry person. Once in
the SSJ state, the Saiyan's heart is filled with anger.
Who perform it: Goku (DBZ Movies 5-8, 10, 12, 13 & OVA), Gohan (DBZ Movies 7-10, Trunks Special & OVA), Vegeta (DBZ Movies 6-9, & OVA) Trunks *Future* (DBZ Movies 7, Trunks Special & OVA),
Goten & Trunks *Present* (DBZ Movies 10-13), Gotenks (DBZ Movies 12), & Brolly was the Legendary SSJ* (DBZ Movies 8 & 10)
-Ultimate Super Saiyan Stage 2: The Ultimate SSJ state is used briefly in DBZ right before
the Cell Game. This state of SSJ increases the Saiyan's power, but not by much. The Saiyan's body becomes totally pumped up.
Who perform it: Future Trunks (DBZ Movies 8 & 9), & Vegeta (DBZ Movies 8, 9 & OVA)
-Ultimate Super Saiyan Stage 3: This stage was only used in battle once. The Saiyan's body
becomes HUGE and muscular. The Saiyan's power is increased by a huge amount during while in this state, however because of the muscular pump-up, the Saiyan is very slow moving and
can leave openings for attacks if their opponent is skilled enough to spot them.
Who perform it:
Future Trunks (DBZ Movies 8 & 9) & Brolly (DBZ Movie 8 & 10)
-The Super Saiyan beyond Super Saiyan:
This was first seen being used by Gohan in the
Cell Saga. His power started to show in the Room of Spirit & Time, but it wasn't fully
unleashed until the Cell Game. It's clear that this is the most suitable form of SSJ to be used in
battle with strong villains. The Saiyan's power is increased immensely and their speed does not
suffer at all.
Who perform it:
Gohan (DBZ Movies 9-10 & 12), Goku & Vegeta (DBZ Movies 12-13),
-Super Saiyan 3:
The most powerful SSJ attained. The Saiyan's hair turns blond and their
eyes turn turquoise, but the major change is that the Saiyan's hair grows to an incredibly long
length and their eyebrows disappear. SSJ3 Goku may even have been the strongest character in
DBZ. Being in the SSJ3 state uses up a LOT of energy and Goku ran out of energy before he
could reach Full Power.
Who perform it:
Goku (DBZ Movies 12 & 13) & Gotenks (DBZ Movie 13)
-Fusion Dance:
A technique taught to Goku by the Metamorian. The move itself combines, or
fuses, two different people into one new person. In order for fusion to work, both characters
must be of the same height, and have the same power level, (if one character's power level is
higher, they must lower it). If these requirements are met, then the two characters must
perform a series of movements that resemble a stupid dance. Both characters must perform the
movements at EXACTLY the same time, and say the words, "FuuuuSION! HA!", also in
unison. If they do not complete all of this, then the resulting fused character could be
disastrous. The two examples shown in DBZ is one very fat person, and a very thin and old
person. However, if executed perfectly in sequence, the resulting character will be a perfect
union of both characters and possess a phenomenal new strength. The movements, and
thoughts of the fused warrior are not at all controlled or determined by the personalities or
moves that the original two possessed. The fusion character is completely unique. All fused
beings are extremely cocky, and usually taunt their opponent while taking their time playing
with them. The downside of this is that Fusion only lasts 30 minutes. After 30 minutes is gone,
the fusion character will split back into the two original characters.
Who perform it: Goten & Trunks (DBZ Movies 12 & 13) and Goku & Vegeta (DBZ Movie 12)
