The Dreadnoks often served as comic relief in the series similar to Cobra Commander, as opposed to other members of COBRA who are serious in their plans for conquest, even when COBRA is being led by Serpentor in the second season and by Golobulus in G.I. Joe: The Movie.
G.I. Joe: Sigma 6
In the series, the Dreadnoks consist of only Zartan, Buzzer, Torch and Machete. Just like their original counterparts, they are a biker gang who are involved in COBRA's plan to take over the world.
G.I. Joe: Renegades
In the series, only Zartan, Buzzer, Road Pig, Monkeywrench, Ripper, and Torch appear as a small-scale but highly dangerous biker gang. They once terrorized a local Kansas town and even get their local sheriff on the ropes. However, the Joes helps the citizens stand up to the Dreadnoks before having them arrested.
