What if Mercury would've left?
 

Remenber the episode during Sailor R that Amy was going to leave to become a Doctor? What if she would've left? Do you think they could've chosen another person to use her powers? would've been the same?

Hmm... good question. Since Amy was a reincarnation of Neo Queen Serenity's royal guard, it would be weird if her Sailor powers could be transferred to someone else.

But then there's the fact that not only did Serena and Amy have a bond, but their past selves did as well, which might mean there's no way Amy could have chosen differently, since there was a power beyond her current age to prevent her from leaving Serena's side until peace was brought.

No way they chose a new Sailor Murcury. I dont even know if they could. Good point about the bond they had leading Amy to make the decision to stay.

Even though it wouldnt happen, it is fun to speculate who would have taken over for Mercury? Perhaps Nuru? Of course that goes against the whole star seed thing. But just having fun.
