Rae Ramon's life was perfect; she worked at STAR labs with her brother Cisco, she was smart and beautiful, and she had awesome friends. But one night, that all changed. One the big night of the Particle Accelerator, something went wrong causing it to malfunction, also hitting Barry Allen with lighting sending him into a coma. Rae, Cisco, Caitlin, and Dr. Wells took the boy and helped him when they realized he was like Rae. Rae was hit with lighting just like Barry except it gave her more powers hidden in one power; Angelic power. She has markings which give her all her powers that make her almost like a Goddess. And with those Goddess powers and her charm, she's basically Aphrodite, which inspired the name.
Disclaimer: I don't own The Flash or any of the characters. I only own Rae Ramon and Aphrodite along with their stories and plot line.
