Amy Pond/Other realities

Alternate counterparts of Amy Pond existed in other realities. These individuals shared similarities with Amy from the Doctor's universe, despite existing in parallel universes or alternate timelines.

The Big Bang
In a timeline where most of the universe had never existed, seven-year-old Amelia still remembered stars in the sky. When she prayed for Santa, she looked outside but saw nothing. Later, Amelia saw a figure slide a brochure through her letterbox. On it was a note, "Come along, Pond." Her favourite school subject and her favourite book had converged, and she insisted her Aunt Sharon take her to the National Museum in London to see the exhibit of the Pandorica and the other mysterious objects from Roman-era Stonehenge. Once at the Pandorica, her drink was suddenly snatched away and she discovered a Post-It Note telling her to wait. Intrigued, Amelia hid and waited for the museum to close. She returned to the Pandorica and instinctively touched it. As her DNA matched that of the mysterious box's contents, it immediately opened whereupon an older Amy from another timeline emerged after being put into stasis for two thousand years. The two watched a brief video about the Pandorica and the legend of its loyal protector, the mythical "Lone Centurion" before a Dalek came to life and was shot by a security guard. The Raggedy Doctor appeared and gave her back her drink, and she soon disappeared due to history being erased. (TV: The Big Bang)

The Girl Who Waited
In one timeline, Amy had been abandoned in the Apalapucian facility for over thirty-six years. She was nearly insane from loneliness. She made a sonic probe to help her fight the Handbots and turned one of them into her pet, naming it Rory. When the Doctor and Rory arrived, she refused to help them rescue her past self, but after a talk with her younger self, agreed to help rescue her if she were taken too. The Doctor betrayed her; only one Amy could be saved. The older Amy gave her existence so her husband and she could have a life together. (TV: The Girl Who Waited)

Short-Change
While at Shops!, Amy encountered a cashier who turned into a purple alien and then a robot Viking. She called the Doctor on her mobile phone to demand an explanation and he said that he "inadvertently start[ed] a galactic space-war" and as a result "the course of human history keeps changing each time something blows up." After hearing this explanation, Amy became enraged when she turned into a ginger-haired dinosaur and the cashier transformed into a chicken. Her biggest frustration was that she lacked thumbs to lock her phone with. (COMIC: Short-Change)

River Song's World
In another alternate timeline, the Doctor wasn't killed at Lake Silencio and a fixed point in time was altered. Amy, due to the cracks, retained her memories of the real timeline and led a group that included Rory and River. The original Amy later displayed knowledge of the events of this timeline.
