Matthew "MatPat" Patrick is a Survivor, available in Chapter XX.5: Theories Unmade.

It had been a long road for his career. Since the beginning, Matthew Patrick - known online as “MatPat” - had crafted and adjusted countless theories for countless video games. Indie horror, simple mobile games, platformers, sandboxes… if the story was unclear, MatPat became the person who tended to unravel it, even if the theories weren’t always correct to what was actually intended. It was him who sparked many others looking through media to make theories, and Patrick had soon expanded from just video games to movies, food and even fashion. As his journey continued, more and more joined his team, and it went from one man making theories to a whole group editing them, helping theorise, throwing idea after idea after idea until something made sense.
And after a long road… MatPat left the scene to be with family. He wasn’t all gone, he was supposed to appear on Game Theory Live, but for all intents and purposes, the main channels were no longer his face.
After wrapping up with everything, Matthew was going on a long trip to celebrate retirement, even if said retirement was not all that different from his job. As he continued to drive, he found the road forcing him to take a detour, one that went by a forest. In front of the forest was a sign attached to a fence, reading:
“KEEP OUT, DANGEROUS AREA.”
Matthew got out of his car, going to inspect the sign before seeing a fog further into the forest. His curiosity got the better of him as he vaulted the fence, and as he found himself enveloped by the fog, MatPat became the face of missing person posters for the next month before slipping into obscurity and darkness…
