Background (with her sister Aya):

They are 16-year-old sisters who are described as mutants, animals, and demigods (daughters of God). They are the only survivors of their home planet, which was destroyed by a black hole made of fire. They now live together on a secret island near Hawaii. They fight evil, such as a villain who brought a zombie plague to Earth, whom they defeated by combining their powers to send the zombies back to their dimension.
