The Omnibots were three Transformers Generation 1 toys available only in the United States as exclusive mail order items. They could be obtained by collecting "Robot Points" from other Transformers toy boxes and sending them to the manufacturer, along with $5 for shipping. During 1985 the number of orders for the Omnibots exceeded expectations by Hasbro, who extended the offer. They had nearly 50,000 orders for Camshaft alone by July.

Original show bibles discovered in 2007 revealed the biography written by Bob Budiansky. This biography describes as a road racer who will do anything to win, including fly right off the road.

Camshaft is an ironic name because the signature feature of the RX-7, a rotary engine, does not have a camshaft. The toy is one of the least known of the 1985 releases as his sub-group, the Omnibots, were three Autobots that were only available by mail-order.

Downshift's function is Security Agent, and he transformed into a white Toyota Supra. This character never appeared in the television series, but did appear in the Generation One Dreamwave comics.
