River Song fought and conquered evil, even when it was in herself. She trained and was tested and had an origin story that began with a little girl and the boy who waited with her.

She put others before herself, and did what was right and necessary even when it hurt. She saved countless lives with her bravery. She even had that all-powerful love, the one for whom every fight was worth, and no sacrifice too great.

River Song didn't wear a cape.

She didn't need one.

But she did have a secret identity.

Melody Pond really was a superhero.
