She is my first OC of Equestria Girls, I named her Sapphire Sky .
I confess that she was previously an old OC for a Teen Titans project that I did not carry out in the end.
Whatever; she is Sapphire Sky, at the end of Equestria Nexus Girls 2 she and others survive the moment when the whole Multiverse returns to normal, I will not say how or why it would be a spoiler; but remember the whole reality of where the ideals come from and blindly follow … from Dark Matter; and blames the Human 7 for destroying their home.
The crystal of your bracelet allows you not only to travel anywhere in the Human World or Equestria, but anywhere in the Multiverse. She is willing to do everything to take revenge on all those who destroyed her world, by any possible means. She also has amazing powers of ice and cold.
