Inkopolis Fallen is an AU created by Modderkin64. At it's core, the Undertale characters were swapped with Modder's Splatoon characters, but this fact has changed most of the Underground. It actually takes place over 12,000 years after a Undertale Pacifist Route, where the Inklings and other sea creatures moved in after the Octarians won the Great Turf War.
