So, what's a saiya-jin? The saiya-jins are a race of primitive warriors possessing an enormous amount of physical power; they're very known for being ruthless and treacherous. Although they don't possess immortality, their lifespan exceeds the lifespan of normal humans.

So how else are saiya-jins different from normal humans? A saiya-jin is born into the world already possessing an amazing amount of physical power. They also progress physically a lot faster than humans, meaning at the age of four a saiya-jin is capable of training as severe as those much older than himself. While humans have to train a majority of their life in martial arts to attain the ability to use ki, it comes natural to most saiya-jins. Oh yeah, a saiya-jin also has a tail.

Tell me more about the tail! Well, it's a tail, but it isn't a simple tail. The tail of the saiya-jin seems to be the key element to a saiya-jin, not only is a saiya-jin more powerful with their tail intact, it grants them certain saiya-jin evolutions. Those evolutions being Oozaru, and SSJ4, but both are temporary evolutions.

Innate Powers

Ki Manipulation: A personal life energy. It can be used to fly, as a source to channel large energy attacks, to sense other people around and determine their power levels, where they are, their intentions, and if they are hurt or are on the verge of dieing. Every person has a capacity of Ki, when their bodies are filled it's considered their maximum power level. Increasing Ki will increase stamina, endurance, strength, concentration of energy, and range of sensory granted by having Ki.

Special Limitations or Weaknesses

Their tails are extremely sensitive, when grabbed their power begins to diminish slowly.

Transformations

Oozaru
Increases to : 1000% of normal form (Strength 1000%, Speed 1000%, Endurance 1000%)
Example Power Level: From 30,000,000 to 300,000,000
Requirements: Saiya-jin tail intact
Physical Change: Transform into a 40 foot tall weremonkey

This form was at one time the most common transformation among saiya-jins. When a saiya-jin transforms into this stage, their bodies are completely covered in fur, their height matches that of a building, and their anatomy closely resembles that of an ape. So basically..they change into giant apes. There's more to this transformation than physical appearance, the saiya-jin's power level increases by tenfold. A saiya-jin not use to the form tends to lose all human traits, and immediately destroys everything in sight in a blind rage. What're the requirements to attain this form? Firstly, you must be a saiya-jin, and secondly, you must have your saiya-jin tail intact. The third and final requirement is that a saiya-jin must absorb a certain amount of rays from the moon into their eyes. Once their source of moon rays ceases, or their tails are cut off, the saiya-jin returns to his/her normal form.

Golden Oozaru
Increases to: 200% of Oozaru (Strength 400%, Speed 0%, Endurance 200%)
Example Power Level: From 300,000,000 to 600,000,000
Requirements: Saiya-jin tail intact, able to transform into a super saiya-jin
Physical Change: Transform into a 40 foot tall weremonkey with golden fur

This form is far more advanced than Oozaru, though the only physical difference is the color of the fur, which has turn golden. Like Super Saiya-jin, this form uses energy in its rawest and most destructive form. Most of everyone has their theory of what Golden Oozaru is and what're its requirements. Here are mine. A saiya-jin must have his tail, must have the ability to transform into a Super Saiya-jin, and must absorb a greater amount of rays than regular Oozaru. Of course a saiya-jin has to have their tail, but why Super Saiya-jin? Because the form deeply resembles Super Saiya-jin, Golden Oozaru is to Oozaru as Super Saiya-jin is to a regular Saiya-jin. Why a greater amount of rays? Well Goku absorbed the earth's rays, and that is a lot more than the moon can offer.

Giji Super Saiya-jin
Increases to: 150% of normal form (Strength 150%, Speed 150%, Endurance 150%)
Example Power Level: From 30,000,000 to 45,000,000
Requirements: Extreme sorrow or anger
Physical Change: Bulkier muscle mass, pupils and iris disappear

Well, this form isn't really a Super Saiya-jin form at all, but it's indeed different from a saiya-jin's normal form. The best way to describe this form is to call it the midpoint between saiya-jin and Super Saiya-jin. This form was only seen in Movie 4 when Goku got really pissed off at Slug. It's very noticeable that this form is the midpoint, a saiya-jin is surrounded by a massive aura of pure energy, a saiya-jin's hair stands and a saiya-jin's eye color begins to change. Along with that comes a massive amount of power. Requirements? Well, a saiya-jin must be near the required power level of attain the Super Saiya-jin form, which could be anywhere from 800,000 and 5,000,000. A saiya-jin must also experience extreme rage to trigger the effect.

Super Saiya-jin
Increases to: 300% of normal form (Strength 300%, Speed 300%, Endurance 300%)
Example Power Level: From 30,000,000 to 90,000,000
Requirements: Saiya-jin must have a pure heart, and a 'need', not a 'want', to trigger the transformation
Physical Change: Bulkier muscle mass, golden hair, emerald iris

Changing into this form holds a lot of benefits. The saiya-jin's power level increases several times over, commonly at least threefold. Along with the strength increase, the saiya-jin attains the ability to harness energy in its purest form, their famous golden auras symbolizing the amazing amount of energy channeled through them. When a saiya-jin first learns to transform into a Super Saiya-jin, it takes months of training to get to the point where it isn't spontaneous, and it happens at will. Requirements? Well, a saiya-jin must first have the required power level, which I feel is 5,000,000 or so. Yes I know some of you think Goku's power level was 300,000, but that was his power level just before the fight with Frieza. After being severely beaten, plus the immense physical strain of using the Kaioken at such high levels, Goku's power level surely skyrocketed. Next, as described by Goku, a saiya-jin must have a pure heart, whether it is pure evil or pure good. The next requirement is debatable, which is a saiya-jin must experience extreme rage. I agree with that, but I don't believe that's the only factor, a saiya-jin must have a reason for transforming, the transformation -has- to be a dire need.

Super Saiya-jin Grade 2
Increases to: 200% of Super Saiya-jin (Strength 300%, Speed 150%, Endurance 150%)
Example Power Level: From 90,000,000 to 180,000,000
Requirements: Must exceed a normal Super Saiya-jin's limits
Physical Change: Even more bulkier muscle mass

Not Super Saiya-jin level 2, but grade 2. When a Super Saiya-jin starts to feel more hidden power within them, they pursue the ascended Super Saiya-jin forms, this being the easiest and first. But this form is basically a beefed up Super Saiya-jin, when a saiya-jin normally entered the Super Saiya-jin form, that was the extent of his/her power, but this form allows the saiya-jin to power up even further as if it was his/her regular form. Physical changes? Well a saiya-jin's muscle mass increases, along with the size of their hair, that's about it. Requirements? A saiya-jin must have trained with the Super Saiya-jin form for an extended period of time, that's about it.

Super Saiya-jin Grade 3
Increases to: 175% of Super Saiya-jin Grade 2 (Strength 300%, Speed -75%, Endurance 300%)
Example Power Level: From 180,000,000 to 315,000,000
Requirements: Must exceed a normal Super Saiya-jin's limits
Physical Change: Even more bulkier muscle mass

Very similar to Grade 2, but this form takes it a step further. This form is a more beefed up version of Grade 2, it's very powerful but it has a weakness. Unlike normal power ups, this forms strength and speed doesn't raise equally, in fact the speed of the saiya-jin drops due to bulky muscles, a heavy price to pay for brute strength. Physical differences? The muscle mass of the saiya-jin more than triples in size, and the saiya-jin's hair grows dramatically as well. Additionally, along with the common golden aura come spontaneous bolts of electrical energy, most likely signifying that the saiya-jin's power is near that of Super Saiya-jin level 2.

True Super Saiya-jin
Increases to: 300% of normal form (Strength 300%, Speed 300%, Endurance 300%)
Example Power Level: From 30,000,000 to 90,000,000
Requirements: Must perfect the Super Saiya-jin power
Physical Change: No distinct changes from Super Saiya-jin

You can call this form 'Super Saiya-jin full power', 'ascended Super Saiya-jin' or whatever you want, but this is the limit of the regular Super Saiya-jin power. This form is complete mastery over the Super Saiya-jin form. A saiya-jin can stay in this form for prolonged periods of time without having to exert energy to maintain the form. While this form's brute strength doesn't really equal that of Super Saiya-jin Grade 3, it's very balanced, it's strength is far greater than a normal Super Saiya-jin's strength, as well as speed, another benefit to this form is that a saiya-jin doesn't have to waste stamina transforming. Requirements? Achieving this form requires a different method of training than the method used to attain Grade 2 and 3. While Grade 2 and 3 required intensive training and powering up in the Super Saiya-jin form, this form requires intensive training coupled with the idea of staying a Super Saiya-jin as long as possible.

Super Saiya-jin Level 2
Increases to: 400% of Super Saiya-jin (Strength 400%, Speed 400%, Endurance 400%)
Example Power Level: From 90,000,000 to 360,000,000
Requirements: Must exceed the limits of a True Super Saiya-jin and have a 'need' not a 'want' to trigger the effect
Physical Change: Increased sharper muscle mass, longer and slightly darker golden hair

This form is officially the second level of Super Saiya-jin. A Super Saiya-jin's power, speed, and stamina all increase in sync when transforming to this form, correcting the mistakes of Grade 3. But this form's power is far superior to Grade 3 and other ascended Super Saiya-jin forms; infact the difference can be compared to saiya-jin and Super Saiya-jin. Along with longer hair, muscle mass increase, a larger aura and a lot of electrical currents, a saiya-jin gains the ability to adjust their strength and speed. Requirements? Mastery over the Super Saiya-jin form, and a dire need to attain the form and/or extreme rage.

Super Saiya-jin Level 3
Increases to: 125% of Super Saiya-jin Level 2 (Strength 175%, Speed 175%, Endurance -25%)
Example Power Level: From 360,000,000 to 450,000,000
Requirements: Must dig a find a vital power deeper and more potent than the ki used to transform in the past forms
Physical Change: Bulkier muscle mass, no eyebrows, three extra feet of golden hair

This is a very hard form to attain, although it can be achieved through extreme rage (Gotenks), it requires an extensive amount of training with the Super Saiya-jin forms to realize that it exists and how to achieve it. Physical difference? This form has the biggest physical difference over all, the saiya-jin's muscle mass increases, eyebrows completely disappear, and their hair length more than triples in length. This form is very difficult to master, and even when it's mastered to the point that a saiya-jin can transform directly to it from theirs regular form, it takes a lot of energy to maintain.

Super Saiya-jin Level 4
Increases to: 400% of Golden Oozaru (Strength 400%, Speed 400%, Endurance 400%)
Example Power Level: From 600,000,000 to 2,400,000,000
Requirements: Must exceed a normal Super Saiya-jin's limits
Physical Change: Fur growth everywhere aside from center torso, a foot or so of hair growth, bulkier muscle mass, crimson pupils and iris

Well this form isn't like the other Super Saiya-jin forms to put it short. It can be described as a compressed controlled version of Golden Oozaru with a significant power increase. This is undoubtedly the strongest of the Super Saiya-jin forms, both rage and sorrow triggers this transformation.

Legendary Super Saiya-jin
Increases to: Power amplifies with rage, uncalculable
Requirements: By whim of fate, must be the one and only legendary super saiya-jin
Physical Change: Pupil and iris disappearance, tremendous muscle mass increase

Some considered this form Goku's regular Super Saiya-jin form, some considered it was Goku's Super Saiya-jin level 4 form, but in both cases, more than one of each kind appeared, so to cover plot holes, Broli was created. The legendary Super Saiya-jin form is far more powerful than Super Saiya-jin. Physical difference? A green aura replaces the normal golden one, muscle mass increases tremendously, and eye pupils fade completely. Requirements? Not every saiya-jin can attain this form, in fact only one can exist at a time and every so many years, so the odds of becoming the legendary Super Saiya-jin is very low.
