Dreadbots are Hector Con Carne's second army, for replacing the Henchmen of Evil Con Carne.
Ghastly told General Reginald Skarr to wait until she finished her coffee break. Skarr put on some tape on the loyalty meter to make the Dreadbots trust Skarr instead. During a training session, Skarr pressed a button to let the Dreadbots attack Hector. They sent Hector, Ghastly and Boskov to jail. After arresting his allies, Skarr created Skarrbot and the Dreadbots made Skarr their emperor.
Skarrbot used a piece of tape that says "Skarrbot" loyalty meter to attack Skarr. This made Skarr quite proud of the betrayal. From now on, the Dreadbots are now led by Skarrbot alone.
It is unknown what became of the Dreadbots, as the episode featuring them ended in a cliffhanger. However, as they are never seen again, it is presumed they were defeated and the Henchmen were rehired or replaced with new henchmen.
The Dreadbots are emotionless robots. They are willing to serve whom they were loyal to.
The Dreadbots have purple armor with silver faces covered in a glass helmet.
- "You are captured. Have a nice day."
- "The troops are ready for you, Emperor Skarr."
