Green Dragon Balls

Origin
In the year 940 age; Piccolo Jr., who was he guardian of Lantare, created the Green Dragon Balls. The Green Dragon Balls have less limitations than the Earth Dragon Balls like anyone can be killed or revived as much as you want, and any wish made with any dragon ball can be undone if you want. The Green Dragon Balls are twice the size of Earth's dragon balls. It grants 1 wish and takes the equivalent of 2 earth years for these to turn back to dragon balls from rock after each wish.

Wishes (so far)
Goku Jr. wishes the Saiyan race to be resurrected without evil in their hearts.
