Amelia "Amy" Jessica Pond was the first companion of the Doctor in his eleventh incarnation. She was the girlfriend and later wife of human nurse Rory Williams and the mother of River Song. When River married the Doctor, Amy became his mother-in-law.
Amy was adventurous and reckless, with a dry wit and a stubborn streak. She had a difficult childhood and felt abandoned by the Doctor; she was rarely open with her feelings and often mistru****l and wary. She held people she cared for at arm's length, as she did in her early relationship with Rory and the Doctor upon his return. As a child, Amelia was stoic and able to care for herself. She prayed to Santa Claus for help with the crack in her wall and was unsurprised to meet the Doctor. She lusted for the adventure of travel with him. When he did not return, she grew into a cynical and aggressive young woman.
Amy was flirtatious. In Leadworth she worked as a kissogram. At one point she tried to seduce the Doctor and Rory claimed she only passed her driving test on her first go because of a revealing skirt.
Amy loved her husband, Rory, passionately and called the Doctor her best friend. Her bond with him was almost religious. She felt he could fix anything. Despite her tough exterior, Amy could not always hide her emotions and was devastated when faced with the loss of loved ones such as Rory, Melody, the Doctor and Vincent van Gogh. She broke down in tears when the Doctor left her on Earth with Rory.
In her time on the TARDIS, Amy was heroic, saving the lives of the Doctor, Rory, River and others. She was willing to remain in the clutches of the Silents to let her friends escape. Her mind, altered by her growing up with a crack in space and time in her bedroom wall, restored erased beings to the universe with only her memories. She knew time could be rewritten and hoped there was some way to rewrite it to avoid the Doctor's death. She could also remember alternate timelines.
Amy could also be cruel though; she certainly had a ruthless streak. In an alternate timeline, Madame Kovarian was being killed by her eye drive and had gotten it most of the way off; she asked Amy to help her because it was what the Doctor would do. Amy said "He's not here" and put Kovarian's eye drive back on, killing her for having stolen her baby from her, though she was later conflicted about this.
