Lauren Faust's early design of Twilight shared a similar color scheme and cutie mark to the G1 pony Twilight, who appeared in the pilot episode Rescue at Midnight Castle. Twilight Sparkle's color scheme was later changed to that of the G3 Earth pony Twilight Twinkle, with slightly different mane and tail. G1 Twilight teleports by wishing, and Twilight Twinkle likes to watch fireflies; Twilight Sparkle shares both aspects of both of these ponies, with her ability to teleport and her occasional stargazing. Though she is much more studious and possesses more powerful magical abilities, she also shares a number of personality traits with Wind Whistler, such as her tendency to rely on logic rather than instincts and her habit of using more advanced and technical terms. In a 2008 sketch for the series bible, Twilight's cutie mark resembles that of the character Moondancer from earlier My Little Pony generations.
