Doom-Bots (also spelled "Doombots" or "Doom Bots") are powerful and advanced robots built by the arch-villain known as Dr. Doom and are often made in his image, if they are not they are instead programmed to obey his word as law - with the famous "Doom's Word Is Law" phrase being heard often. Doom-Bots, although loyal, have not been without error and a few Doom-Bots have rebelled against Dr. Doom either as heroes or villains: Dr. Doom has shown that some of his Doom-Bots have a self-destruct sequence inside themselves that he can activate (or force them to activate), should the need arise.
