Shen-ron
Created in the year 470, Shenron is the dragon god who appears when all seven Dragon Balls are gathered in one place and a person utters, "Come out Shenron!". At first, Shenron can only grant one wish, and bring someone back to life once, but later, he recieves a power-up from Dende which allows him to grant three wishes at one time and grant the same wish twice. However, after all three wishes are made, the Dragon Balls will scatter across the Earth and turn to stone. In one year's time, they will return to normal and can be used again. If not all three wishes are not used up at one time, the waiting period is shortened. Shenron is linked to his creator Kami, thus if Kami dies, the Dragon Balls become useless. Later when Kami merges with Piccolo, the Dragon Balls turn to stone, but Dende replaces Kami and becomes the new God, at which point he powers-up the Dragon Balls and restores them. Shenron was killed once in the series by Piccolo Daimaou. The dying process does not work in reverse, in other words, if Shenron dies, Kami does not. After Shenron's death he can be reborn by a simple procedure. In Kami's Palace is a mini statue of the Dragon. If the dragon is dead, the staue will be broken into pieces. In order to ressurect him, you must simply put the statue back together again. Shenron cannot grant wishes that exceeds laws of nature, or the power of his creator. (Power meaning fighting strength). Shenron cannot ressurect someone who has been dead for more than one year, (which makes the Time-Line is DBZ Daizenshyu 7 a bit of a plot hole since Gokou was listed as being ressurected more than a year after his death). And he cannot ressurect someone that has died of natural causes. Whew! That's a bit complex. Hope you got it all.
