Theodore Peterson

Theodore Peterson, (better known as "The Neighbor" or Mr. Peterson") born in 1955, is a famous theme park designer known across the world, and is the main antagonist of Hello Neighbor. He has a wife and two kids, and moved into Raven Brooks from Germany after a horrible accident happened on the Ferneh Welt. They moved into Theodore's childhood home in 910 Friendly Court, which used to belong to his parents. His very first amusement park was in 1984, and was in a place named Bosco Bay. He built parks across six continents and his most recent one was in Raven Brooks. The Golden Apple company got Theodore to design a theme park for them, which was called the Golden Apple Amusement Park. According to himself, he makes parks so people can escape the scary world just for a little while. He works in his office in the basement all the time and barely coming out to talk to his family. He is a family man, as he will do everything he can to make sure his family is safe. However, an accident happened, and he had to protect his son by locking him in his own basement. He works in his office in the basement all the time and barely coming out to talk to his family.

Early Life
When Theodore was a child, he always played around in his house with his best friend Ike Gershowitz. His parents were popular meteorologists and built a meteostation. Theodore used to sometimes go to the tunnels below it with Ike. However, the town became suspicious of his parents and what they were working on, and the parents were becoming a little unhinged. Sometime in the late sixties to the late seventies, they mysteriously disappeared.

The Secrets of Bosco Bay
In 1984, Theodore was working on an amusement park in Bosco Bay, and used the brother of a girl named Jen to test one of his rides. To Theodore's surprise, the brother died. Jen took it the wrong way and thought Theodore had some kind of "plan."

The Ferneh Welt and the Peterson family's Bad Blood
In 1991, Theodore's park in Germany was closed after an accident happened on a Flume Ride resulting in the death of four teenagers, who drowned. The Peterson family quickly left and moved to Raven Brooks, Missouri. The house they moved into belonged to Theodore's parents. Theodore joked about taking his son's new room since it used to be his. Theodore set up an office in the basement and started working down there a lot. He noticed his son's unique drawing talent and it intrigued him. A little while later, the Golden Apple corporation asked him to make an amusement park for them, which he agreed to. Theodore reunited with Ike Gershowitz and they ate pizza for dinner at the Peterson's house. However, Theodore got angry at Ike and told him to leave. Ike went missing after that. His wallet was found in a tunnel.

The Mystery of the Puzzle Master and the Grave Mistake
The Golden Apple Amusement Park opened, and a girl named Lucy Yi was in the front cart of the Rotten Core Roller Coaster. Due to the lack of safety features and the work of Gordon Cleave, she fell into a tree and died. Not long after, two detectives from Germany came to try to get Theodore arrested for the Germany accident, but they failed. After Ike's wallet was found, Theodore stole it and worked in the basement for weeks. The wallet had pieces to a secret device in it, which Ike found from Theodore's parents. Theodore made his own device with it, and it worked just like any of the other devices. It was able to give the user good luck but gave the people without it bad luck. It was stolen by a society of humans in bird costumes called "Forest Protectors" before Theodore was able to give it to the Puzzle master, who was going to keep it safe. The Forest Protectors used it in a ritual when a storm started and gave the town bad luck. However, it didn't seem to work, due to two of them being arrested and one losing their job not more than a day later. During this ritual, the Lucy Yi ceremony was also going on, and the Golden Apple Amusement Park burned down, causing the forest it was in to start catching on fire and the tunnels near where the rituals happened to fill with smoke and collapse.

The Missing Pieces
In 1995, Theodore's son befriended the kid across the street, Nicky Roth. One time Nicky came over for a sleepover and got into rooms he wasn't supposed to while looking for a glass of water and Theodore spooked him back to Aaron's room. Later, He and his wife leave to go to a store. Sadly, they get in a wreck with a pizza truck and Diane gets injured. Theodore waits in the hospital until she eventually dies. His son got really mad and accidentally pushes his sister off the roof of the house while playing a game. Mya gets buried in the backyard. At Diane's funeral, Theodore was inside the house and he started having a breakdown. He locks Aaron in the basement to keep him from dying like Diane and Mya, and becomes extra unhinged.

Nicky's Waking Nightmare and the Neighbor's Buried Secrets
Theodore was searching the Golden Apple Amusement Park for scrap parts for his basement. He told the town that Aaron and Mya were with an Aunt Lisa in Minnesota. One day, while chopping up meat, he realized Nicky was in his house, due to the piece of tape left on the front door that moved. He walked up to the closet he suspected Nicky was in but his doorbell rang and it distracted him. Theodore's wife's phone book got stolen by Nicky and it turns out Nicky's friend bribed a mailman to ring the doorbell to save him. Theodore angrily went back to his work. Later, he entered Nicky's house and stole the phone book back. Half a year later, Theodore tried to frame Nicky by setting up random scenarios, and it worked. People weren't sure if Nicky was innocent, causing him to lose his friends. One night, Nicky entered Aaron's window, but Theodore figured out how he entered, and the next morning he chopped down the tree Nicky climbed.

Hello Neighbor
After a long time of working, Theodore realized Nicky broke into his basement. He locks the door back, trapping Nicky in. Using another entrance, he looks for Nicky and then he finds out Nicky wandered into his underground amusement park and welcomed him. The park resembled a prison, and Nicky was trapped. 2 months later, Aaron let Nicky out of the room, and he had to escape the house. Theodore attempted to chase Nicky across the street, but Aaron distracted him and Nicky got away.

Missing Criminal
Not long after, Theodore was wanted by the police due to Nicky telling about him, but then Theodore went missing, and no one can find him.
