Indigo Zap's hairstyle, goggles, and eye color closely resemble those of Lightning Dust in animation. The prototype of Indigo Zap's toy model also shares Lightning Dust's hair and skin color. On the My Little Pony Equestria Girls: Friendship Games DVD/Blu-ray audio commentary, Ishi Rudell mentions that Indigo Zap's role in the movie was originally going to be Lightning Dust, with Josh Haber adding that Spitfire was also considered, but felt she "wasn't quite mean enough". Indigo Zap was created due to the writers wanting a new character.
