Tri-State Area is the metropolitan state, surrounding Danville, and by extended the home of heroes like Phineas Flynn, and Ferb Fletcher, and of villains like Dr. Heinz Doofenshmirtz. While Danville appears in most of the villain tournaments context, giving a slight mention to the metropolitan state, Tri-State Area's name and field appears as one of the main battle sceneries of the second Disney vs. Anime Villains War.
