River Song

River Song (also known as Melody Pond) is a canon character from the new series of Doctor Who.

Canon History
River Song is the daughter of Amy Pond and Rory Williams, companions of the Eleventh Doctor. In some time between the Ponds' wedding at the end of the fifth series and the beginning of the third, a pregnant Amy was taken captive by the Silence, a religious order that wants to see the Doctor dead because of their belief that "Silence will fall when the Question is asked", and kept in confinement until River (called Melody at this time) was born. A clone of Amy accompanied her husband and the Doctor on their travels during the first half of the sixth series.

The infant Melody was taken from her parents despite a rescue attempt, and raised in an abandoned orphanage and trained to kill the Doctor. As a young child, Melody discovers that she can regenerate like a Time Lord after her mother inadvertently shoots her. The second Melody, now Mels, goes back to her parents' childhood and grows up with them as their best friend, actually becoming pivotal in the development of her parents' relationship (turns out her parents would eventually name their daughter after this childhood friend, so she basically named herself. Never apply logic to Who).
