>>93547924>Why did Rose have the ability create zombies?Because Gems are magic and sometimes they have OP powers? In this case, I feel her class was intentionally designed to just heal minor injuries in both humans and Gems, but she furthered her ability after becoming free-thinking like Peridot discovered her metal powers
>Can other Gems do it?Probably, there are a lot of Gems, and definitely so if we include the Rose Quartzes at the Zoo, but they probably never discovered their ability.
>Why hasn't it happened more often?Maybe it has. Although, the ethics of resurrection is questionable and it seems that the beings she brings back not only turn pink, but gain some kind of connection or devotion to her, they are not even quite the "same" person (Lion, Lars, Pearl)
