"Well, if it isn't the Kids Next Door. Have you arrived to abscond with our birthday cake like you do every year?" -- The Delightful Children from Down the Lane
The Delightful Children From Down The Lane, or the DCFDTL are the conceited "perfectly behaved" children bent on the destruction of the Kids Next Door Organization and the supremacy of adults over children. The DCFDTL are, for all intents and purposes, one single being; they always speak in perfect synchronization and stand together in group formation at all times. Their known names are: Bruce (short, blond boy), Lenny (helmet boy), David (tall, brunette boy), Ashley (tall, blonde girl) and Ogie (brunette chubby girl).
Although the Delightful Children are in service of Father, they are seen acting independently from him just as often as not. The Delightful Children rarely partake in direct physical combat, usually sending other villains to do their work and controlling large combat machines. They make more appearances in the series than any other villain, and more than any character other than the five members of Sector V. They are also obsessed with behaving properly and wish to become adults as soon as possible.
Their Taiwanese babysitter is named Mrs. Kwan.
