One day in Ponyville, a boastful Inventor comes in to show off his greatest creation: the Robotic Artificial Colt number 7, its part colt and part machine. He claims to be twice as strong and fast as the average pony, and that its the next generation in ponykind. He even states that it's better than the new "princess twilight". But the mane 6 ran him out of town, but he left the machine behind for dead. Twilight asks the machine where he will go, but he has no idea especially since he had no idea what friendship was. Thus, Twilight takes RAC in and tries to teach him all the values of friendship and prove that he is more pony than machine.
