Matthew Robert Patrick aka MatPat is the creator of the “Theorists” brand of YouTube channels including The Film Theorists, The Food Theorists, The Style Theorists, and of course, The Game Theorists. As the name implies, the videos are based on theorizing, and MatPat is the undisputed champion of theorizing about “Five Nights at Freddy’s” lore. That doesn’t mean he’s right 100 percent of the time, but Scott Cawthon has previously confirmed that MatPat has figured out plot points before it became confirmed canon within the games. This does mean that sometimes fans take his theories at face value, forgetting that a theory is just that — a theory.
“FNaF” lore is admittedly convoluted, and part of the fun of being a fan is trying to make sense of the sprawling landscape of characters, locations, timelines, and killings. Some of the lore of the franchise is not even included in the actual games but in the companion books and graphic novels. Not everyone has the time or desire to read all of them, so watching a MatPat video is a great way to gather information they might have missed. Regardless of anyone’s personal opinion on MatPat as a creator or theorizer, he’s a major part of why “FNaF” has gained such popularity. He offers a service of helping get new fans up to speed or help confused fans make sense of a pretty complicated franchise, even if he doesn’t always get it right.
It seems odd to have a variety of YouTubers have cameos in “FNaF” without including MatPat, but as of publication, he’s not been confirmed to appear. He’s done some trailer reaction videos that show him commenting on the cameos of his colleagues but has not said anything regarding his own involvement. So either he’s not involved, or he’s hiding a pretty big secret.
