A lifelong daydreamer and inventor, nine-year-old Lunella Lafayette picked up the name Moon Girl from teasing classmates, thanks to her head-in-the-clouds demeanor. Her obsessive interest with the Kree led her to invent a device to track down that alien race’s technology, and Lunella then discovered a Kree Omni-Wave Projector. Her teacher accidentally activated it, which brought a tribe of primitive Killer Folk from an alternate Earth to Lunella’s. Along for the ride was the 20-foot-tall red Devil Dinosaur, who wanted revenge on the Killer Folk for the death of Devil Dinosaur’s former partner, Moon Boy.
Moon Girl and Devil Dinosaur formed an instant bond, and Moon Girl confessed her secret to her new ally: Lunella discovered she was a NuHuman, or a Human/Inhuman hybrid, and was terrified of undergoing Terrigenesis. Many adventures later, Lunella did indeed undergo the process, and came out the other side with the Inhuman power to switch minds with her dinosaur.
Between the Moon and New York City
Primarily, Lunella is aided by her genius-level intelligence when fighting the bad guys. Surpassed by nobody in terms of intellect, Lunella is the smartest person in the world...as a mere child.
The ten-story-tall beast called Devil Dinosaur assists Lunella in battle. Devil Dinosaur possesses human level intelligence, along with sharp claws and a vicious bite, which makes him a formidable ally. Moon Girl’s Inhuman ability also allows her to swap consciousnesses with Devil Dinosaur. This power is triggered due to stress caused by anger or hunger, and only during a full moon.
Lunella carries along a variety of tools and gadgets—invented by herself—to aid her heroic pursuits. These devices are bizarre, but functional, including a spring-loaded boxing glove and a taser.
