So the story for Adventure-Mode: Remember Sally the Calico Cat, from that Mystic Island contest? She gets corrupted into Dark Sally and threatens both the Ideaverse and Randomverse (and maybe the DreamFiction version of Earth with all its extra countries with names like "El Kadsre" and "Kittenolivia" that aren't on a typical world map; I think we should start out by crossing over the Idea and RandomNess wikis first, then explore other options (Tyruswiki crossover?) later). Dark Sally's moveset is similar to Tabuu in SSBB in the first 4 "waves", followed by 6 more "waves" with Master Core's behavior and moveset.
