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 battery pack could also power several figure-held accessories such as a Radar Scope, Space Gun and underwater light via jack and corded plug.

The earlier versions of Billy Blastoff had twin red air tanks (resembling twin scuba tanks), featured a helmet with coordinating red trim and a space suit with a blue belt and suspenders.

In 1970 Billy was remolded to better match the spacesuits of the Apollo Astronauts with an all white helmet, a more rectangular beige air supply, restyled space suit and black (as opposed to yellow) gloves.

Like the earlier version this Billy Blastoff could also power vehicles with the gear at the bottom of the air supply / back pack.
