Lunella Lafayette is a young African-American girl who daydreamed and loved to invent. Despite possessing an astoundingly large intellect, she is unable to get into better schools and attends Public School 20 Anna Silver. Her classmates make fun of her and dub her Moon Girl because of these qualities. One day, Lunella becomes obsessed with learning about the Kree and discovers an Omni-Wave Projector thanks to a device she invented. Her teacher Coach Hrbek accidentally activates the machine and opens a portal that brings in a group of tribal creatures called the Killer-Folk. They were followed by Devil Dinosaur, who was looking to avenge the death of his longtime partner Moon-Boy. Lunella encountered Devil Dinosaur and suddenly formed a bond with him.
