Two great characters that I feel have never been used are the Duocons, Flywheels and Battletrap. Sure, they were apparently used in the Headmasters cartoon in Japan, but I didn't even know that existed until the advent of the Internet. Battletrap kinda appeared in the Marvel Transformers comic, but that was nothing more than a nonspeaking role. Flywheels showed up for two seconds during the opening credits for "The Rebirth", so there's that, I suppose.
