This song fits the heroine of my story, namely how she gets her powers plus her general mindset. She never gives up unless their is a good reason to. Not as cool as the villain's theme song but still good.
This song would fit the villain in my fanfic perfectly. She is a covert operative, seeking to overthrow the government on her own home world. She was banished from her home world and is now in disguise on Earth. There she runs into the heroine of my story, who eventually get's superpowers in part due to the villain's meddling.
