The title character in this Jonny Quest adventure is a mad scientist who has invented a mechanical cloud. With this device, he is able to pull aircraft out of the clouds. Intending to take over the world, the scientist must be stopped -- and the Quest Team is given the responsibility of doing the "stopping." "Warlord of the Sky" debuted in syndication on November 16, 1986, as part of the weekend "Funtastic World of Hanna-Barbera" series; it was later incorporated in the standard Jonny Quest package, along with the "classic" episodes from 1964-1965. ~ Hal Erickson, All Movie Guide
