Theodore Peterson

Theodore Peterson is a man in his fifties. He has grown a stubble as compared to the first game, probably due to him living in isolation for months to escape the police. His scary-looking greasy black rubber gloves are on him at all times, with his sleeves rolled up. Theodore's brown but graying hair forms into a swirl at the top of his head, and his iconic mustache is always curled at the sides. His thick eyebrows are normally arched, and point down toward his red triangular nose. Theodore has green eyes, and seems to be sleep deprived. He has strong cheekbones and a round chin, and has wrinkles and creases on his forehead. His shirt is a yellow collared shirt, with a stain on the left collar. The very small pattern on it resembles a rain-resistant material. The sweater vest he has over the shirt is blue, with a diamond argyle pattern on it. The edges of the vest are dark blue and ridged, while the diamonds are a lighter blue. There are white dotted lines crossing the vest as part of its pattern. Theodore's pants are an orange color with darker orange stripes, and his shoes are black and white sneakers.

His main passion was designing blueprints and ideas for theme parks. Theodore Masters Peterson, also known by his nickname the Neighbor, is an unemployed and unhinged maniac. A former international amusement park designer, he started to slowly lose sanity after multiple people died on amusement rides designed by him. He did much for his family, and wanted to protect them. After the death of two of his family members, his son, Aaron, is the only person he has left. From Theodore's perspective, the partners he worked with in the various amusement park sites were not very fond of him, and cared more about the money gained from the rides. While he faced all these issues, he still tried to make his family happy.

In 1977, he married Diane Peterson. At the time, he was 32, but Diane's age is unknown. The two had a good life, traveling the world. Theodore's life really began to go downhill once he moved to Raven Brooks, the hometown he lived in as a child. He began his final park in 1991, the Golden Apple Amusement Park, after making a deal with the Golden Apple Corporation. He witnessed many on-site accidents, and had an office in his house where he investigated each accident, using various photos. He started to slightly detest his son, after assuming he was an Omen of some kind, due to him being at each site accident when they happened.When the Golden Apple Amusement Park opens, Theodore starts to creep out Aaron's friends more and more, and then Lucy Yi's death happened. Theodore didn't go to her funeral with his family, nor did he rarely talk to them. He spent most of his time in the basement, working on various devices and gadgets. At this time, he is partnered with the new Puzzle Master, Norman Darby. Theodore is aware of what the devices he works on are capable of, and decides to leave them in Darby's safe hands, Norman clearly being one of the people Theodore trusts the most. He was also keeping secrets from his own son, by stealing a wallet Aaron found, and denying any sightings of Ike Gershowitz, who Theodore already seemed to know was dead at the time. Theodore was becoming more and more secretive, and then one day he lost the person whom he loved the most, Diane. He seemed to have gotten stressed while driving and went 30 miles per hour at a street corner, resulting in a car collision. Theodore went into depression, and spent days not interacting with anyone, until he finally snapped at Aaron, who was bullying his sister.

Once Mya died, Theodore knew he had to keep his son safe from the authorities, so he locked Aaron in his basement, then his whole attitude completely changes. Theodore is now acting weirdly, pacing his house, seeming to have a schedule for where to go on certain days of the week, whether it was the Hall of Records, the Park, or the Basement in his own house. He knew he had to keep his son out of anyone's sight, but once his neighbor Nicky Roth became suspicious, he knew he had to lure Nicky into his basement too, using Aaron. Theodore's car was a mess due to the crash, but once the Police began to surveil his house, he knew he had to move. He turned an abandoned museum into a living space, behaving weirder than he did before, except this time he would physically throw out anyone who entered his house, instead of intimidating them until they left. He would actively threaten people who confronted him, and try to scare them off if they got near.
