Shelli was born as the result of a sperm and egg donation to a lab gone wrong. Instead of being conceived inside a pregnant woman, she was conceived inside a container located somewhere in the lab. To explain the bizarreness of her backstory, she created a complex secret level inside of Noki Bay.
Shelli has the most bizarre backstory out of everyone in the Human Sunshine Project.
According to "Welcome to BrantSteele, ZOMG", Shelli was the first victim that Zeke O. Mikey Gargan killed.
