Cyberon

Cyberons were an "unlicensed" species. They desired to complete themselves by gaining the "ears" they lack, which, by making them properly licensed, would allow them to gain fame and fortune through merchandising.

History
Through false promises, the Licensor ensnared a few Cyberons into his service, sending them to what he believed to be Earth as his agents, alongside some regular Autons. The Licensor's schemes were foiled by the Chiropodist (or "Foot Doctor"), who had in truth tricked the Licensor and his party onto Unlicensed Earth, which, due to the ironclad laws of the Licensor himself, thus ceased to exist with them on it. Prior to this, the Foot Doctor had revealed the deceitful nature of the Licensor's deal with the Cyberons, causing them to turn against him. (NOTVALID: Do You Have a Licence to Save this Planet?)

Behind the scenes

 * The Cyberons originated in a standalone series of home video releases by BBV Productions, also of interest to Doctor Who for the character of Lauren Anderson, who debuted in the first Cyberon film and was reused in the Who spinoff  When Being You Just Isn't Enough.
 * As Do You Have a Licence to Save This Planet not-so-subtly pointed out, the Cyberons were originally conceived as stand-ins for the Cybermen, with the only major difference in design between the two races being the Cyberons' lack of the trademark handle-like tubes on their Cyber-helmet — what the parodical Cyberons in Do You Have a Licence to Save This Planet refer to as "ears".
