ABOUT THE DRAGON BALLS

USING THE DRAGON BALLS
In all, there are five main rules/steps/requirements to use the Dragon Balls.
1. Collect all 7 Dragon Balls.
2. Do not hesitate in wishing because the Eternal Dragon will leave.
3. Basically the same thing as above: think of your wish before summoning the Eternal Dragon.
4. Don't attempt to attack the Eternal Dragon. His powers are strong. You will die in a blink of his eye.
5. After the wish is made, the Dragon Balls will scatter all over the Earth. They will also become stone for a period of time.

THE EARTH DRAGON BALLS
The Dragon Balls were created by Kame, the guardian of Earth, who escaped the Planet Namek as a young boy and crashed on Earth with no memory of his home planet. In order to become Guardian of Earth, he was forced to seperate himself. The old, wise, good Namek became known as Kame, while his evil self came to be known as Demon King Piccolo, the "father" of the current Piccolo. While the evil Piccolo terrorized the world, the good Kame stands guard over Earth atop his Lookout, also the location of the Room of Spirit and Time and the Pendulum Room. This is where also the place where Kame created the Dragon Balls.

The Earth Dragon Balls are about the size of a baseball and are yellow, each with 1-7 red stars on them to identify them. Whenever someone collects all seven of the balls, they can summon the Eternal Dragon, Shenlong. The Eternal Dragon will grant them one wish. In DBZ, the Dragon Balls are mainly used by the good guys to resurrect people from the dead, but the bad guys usually want immortality (the only one I know of to succeed was Garlic Jr). Unfortunately, the Dragon will only grant the wish once...ever. So if someone is resurrected and they die again, they cannot be ressurected again. (Note that this does NOT mean only one person could ever be resurrected. Shenlong will grant variations of the same wish)

Also, the Earth Dragon Balls made by Dende after Kame's "death" can grant two wishes, but they can still only resurrect a person once.

THE NAMEK DRAGON BALLS
The original Dragon Balls, these are about 4-5 times bigger than the Earth Dragon Balls, closer to the size of a basketball. The Namek Dragon Balls work the same as the Earth Dragon Balls except for three variations:

1) They will summon a different Dragon, Porunga.
2) You must say Porunga before the balls will summon the Dragon.
3) You must make the wish in the Namek language.

Unlike the Earth Dragon Balls, the Namek Dragon Balls will grant three wishes. Also, since they are the original Dragon Balls, they are capable of resurrecting anyone or any group of people an unlimited number of times, as long as the death was unnatural.

THE BLACK STAR DRAGON BALLS
These Dragon Balls first appeared during Dragon Ball GT. They are identical to the Earth Dragon Balls, except they have darker stars on them. They are stronger than the Earth Dragon Balls, therefore their wishes cannot be reversed by any other Dragon Balls. Oh, there's also one other big catch: if the Black Star Dragon Balls are not brought back together within one year of the wish being made, whatever planet the wish was made on will explode! And, if that's not enough for you, the Black Star Dragon Balls don't scatter over the Earth, but over the entire Universe, making them much harder to find.
