- Senator of Maine during a speech heard in HeroFall: Prelude to Siege
The Republic of Maine is a new Friendly Faction in the Ubisoft-Pixar Crossover Universe, first appearing in the HeroFall Franchise. It is affiliated towards The Winslow Accord and its United States of America, and they are made up of 6 States within the Northeastern United States who seceded from The Common Defense Pact and American Confederacy of The CDP, being one of the few States on the East Coast to resist the CDP during the Hero Civil War.
