According to former game director Isaac Christopherson in a Twitter Q&A following the release of Chapter 5, the Prototype (who makes his full debut in the chapter) went through various changes compared to his original draft for the game. Although the twist that the Prototype was actually Spoiler:Ollie and him having a jester head were both always planned, his design was originally planned to be more akin to Catnap's shrine seen in Chapter 3, as well as having multiple Grabpacks in his back to lift himself. He also had a different personality, with Christopherson noting that he would "never speak as though he knew he was the bad guy". Additionally, while the idea of having Elliot Ludwig be the human origin of the Prototype was considered, they didn't go through with it due to being "too obvious".
