6. Renesmee
In the second installment of the last book, we see a more grown up Renesmee, as portrayed by actress Mackenzie Foy. As the Cullen family try to prove she was conceived naturally and isn't a bitten immortal child, we will see as she grows at high speed unnatural for a human or an unchanging vampire. She also brings with her a power, but what is it and will it help their case?
