The Doctor’s companion introduced in “The Eleventh Hour” is Amy Pond. Played by Karen Gillan, Amy first appears as a child named Amelia Pond, who encounters the Eleventh Doctor after he crash-lands near her home.
When the Doctor returns years later, Amy is an adult and has become a kissogram in the village of Leadworth. The episode establishes the unusual time gap between their meetings, a pattern that becomes important to her story. Amy then travels with the Doctor alongside her fiancé, Rory Williams.
Amy is one of the central companions of Steven Moffat’s early Doctor Who era. Her storyline involves the mysterious crack in time, the Silence, the loss and restoration of her daughter Melody Pond, and her later life with Rory in the past. Viewers sometimes confuse Amy with Clara Oswald, who became a companion later, or with Martha Jones and Donna Noble, companions from earlier eras.
