All 7 Dragon Balls after being collected.
Dragon Balls are the namesake artifact of the Dragon Ball series. They are orange, crystalline spheres with the ability to call forth a colossal dragon which has the ability to grant wishes to anyone who gathers all seven of them.
The most notorius Dragon Ball is the Four-Star Dragon Ball, being the one Grandpa Gohan had and which Goku kept after he passed away, also being the one which Goku put on his first son Gohan's hat. The Namekian Dragon Ball Vegeta, and that was later stolen by Gohan, was also the Four-Star Dragon Ball. In Dragon Ball GT, the only good Shadow Dragon, Nuova Shenron, was the Four-Star Ball's Dragon.
