The Delightful Children from Down the Lane (Codename: Kids Next Door)

Father's eerie children, supposedly an adult's view of the "perfect" kids. They are educated, well-dressed and polite, but uncivilized in their burning hatred for the Kids Next Door. They always appear clustered together, move as one and speak in perfect unison. They are the most recurring villains of the show. They are voiced by Benjamin Diskin, Dee Bradley Baker, and Cree Summer. As Sector Z, they are voiced by Ogie Banks, Jennifer Hale, Tom Kenny, and Dave Wittenberg.
