Gobots - Race of robots from the high-tech planet GoBotron on the sci-fi animated series CHALLENGE OF THE GOBOTS/SYN/1984-85.  Landing on Earth, a renegade band of evil robots from GoBotron try to enslave mankind but their conquest of the planet is thwarted by a band of good robots from GoBotron called the Guardian Robots. Their major defensive capabilities enable their metallic bodies to transform into various vehicles (tanks, trucks, cars) used to defeat the bad bots. The Guardian robots consists of Leader 1 (Lou Richards); Turbo (Arthur Burghardt) and Scooter (Frank Welker). Their chief robotic nemesis is Cy-Kill (Bernard Erhard) who commands a band of iron-clad evildoers. This half-hour Hanna-Barbera cartoon was based on a popular Tonka Toys character of the same name.
