The Five-Star Earthling Dragonball is one of the Earthling Dragonballs.
Started cracked in Dragonball Xz.
After the Dragonball was restored, dark TRUNKS used it with the others to summon Shenron.
Scattered across Earth somewhere.
Due to their overuse, the negative wish energy within the Earthling Dragonballs caused the Five-Star Earthling Dragonball to crack, releasing the Shadow Dragon, Rage Shenron.
