Lunella Lafayette is a preteen genius who wants to change the world! That job would be a lot easier if she wasn´t living in mortal fear of her latent Inhuman gene. Just when she thinks she´s found a solution, Lunella´s life is turned upside down when a red-scaled beast is teleported from the prehistoric past to a far-flung future we call...today! Together they´re the most Marvelous Team-Up of all - Moon Girl and Devil Dinosaur! But will they be BFFs forever, or just until DD´s dinner time? When the Terrigen Cloud finally finds Luna Lafayette, her transformation isn´t what you might expect! Plus: The most wanted T. rex in NYC is running out of places to lie low - a problem that won´t get any easier when our darling duo undergo a body swap! It´s a big change-up that will see Luna spending a freaky Friday (or whatever day it happens to be) as Devil Dinosaur, and vice versa! Luna´s got a huge future in the Marvel Universe, if only she can survive the present!
