This is my first ever crossover I created as a writer. Now, I'm combining Terraria Calamity with Super Mario Bros, Annoymoose Monster Girl Saga, Sonic the Hedgehog, and Monster Girl Quest. Sounds very massive, but each world will get equal amounts of time and fully interact with each other. I will update whenever I get the time, but I'm very busy with projects and school work at the time. EDIT: Sorry for the long hiatus. I'll be continuing shortly, but now I decided to add Metal Slug to the mix.
