Throughout the production of a series, a lot goes on behind the scenes in regards to planning and design, which often go through multiple stages before resulting in the final version that is seen on screen. Some concepts and ideas can have an effect on the show and characters, and unexpected occurrences during production can also lead to changes and additions to the plans for the show.
- Monty Oum stated during the August 21st, 2014, Rooster Teeth livestream that Neo's design is partially based on a presentation-play cosplay of Torchwick made by one of his friends (Sonja Carter aka SoulFire Photography).
- Her color scheme is based around Neapolitan ice cream.
- According to Gray G. Haddock, Neopolitan was created from scratch about ten days prior to her debut after Monty had the idea for her. She was inserted into the shots of the White Fang rally in "Painting the Town..." just a couple of days before the episode was finished.
