After Celestia got upgraded into a robot pony known as C-001, she knew what she had to do next. Her beloved Equestria had to become like her. Metal, shiny, and perfectly robotic. Her first target? Her very own sister.
Luna didn't have much of a chance against the perfection that was C-001 and soon enough, her body started to change and alter into its more perfect form, much to her horror, of course. When the programming finally set in, she stopped seeing this as something bad, but actually completely approved of it. Time to upgrade those inferior organic ponies into their perfect state of metal and wires.
