I don't think Franklin Murray is part of DC Comics. DC has a vast array of characters, but this name doesn't ring a bell among the popular or established ones.
There could be a bully character. Bullies often play a role in stories about new kids. Another possible character could be a friendly teacher who helps Murray Heyert adjust. Also, there might be a popular kid who at first ignores Murray but later becomes his friend.
Definitely. Norman Bates is purely fictional. He was created by authors and has appeared in books, movies, and other forms of entertainment to thrill and scare audiences.
In most cases, Norman is not based on a true story. It's more likely a creation of the writer's mind to entertain and engage the audience with an interesting fictional narrative.
The Center of the Heavens was a heavenly novel by Wu Shan Buyu. It had been updated to 205 chapters. The story was about the life of a failed writer, his adventures with the homeless Tony, Rocket, and Yan Shuangying, who played with nuclear bombs. This novel was available on Qidian Chinese Network for some chapters to be read online, and there were also updates for the latest chapters.
