(It's imperative you have the ability to voice a British accent. This is who William is. It's literally 30% of his personality.) This British mostly-taking-the-form-of-a-decaying-rabbit man was the Fazbear murderer. Only one form of him is truly open about his regrets, and throughout the series, he takes 3. Springtrap, Scraptrap, and Glitchtrap, known as Snooftrap in the series because I accidentally made a meme. The regretful form is the original Springtrap. It's an ongoing joke that Glitchtrap curses way too much. We'll be using the censor sound because William's voice actor doesn't actually say the words. You just say the required things to know which curse word it is. Such as "ing", "sh", "a" and etc. You can say "damn."  Springtrap is the form in the profile picture.
