The toy line known as Billy Blastoff incorporated several versions of a four-inch-tall, plastic, child-faced adventurer produced by Eldon in the late 1960s and early 70s. The concept appears to have been licensed from Tomy (of Japan) by Eldon for distribution in the US, Canada and Europe. Billy Blastoff was sometimes packaged as a deluxe Space Set with his friend Robbie Robot (Robbie was also featured in his own packaged set). Billy and Robbie could be purchased separately or packaged with equipment in different Action Sets. Vehicles made for the figures were powered by a gear beneath the figures' pack which also held "AA" batteries. The battery pack could also power several figure-held accessories such as a Radar Scope, Space Gun and underwater light via jack and corded plug.
