Brotherhood of Evil

In published DC Comics continuity summarized in the provided sources, the Brotherhood of Evil was founded by the Brain, a scientist whose cerebral tissue was preserved after Niles Caulder murdered him to create Robotman without consent. The Brain's intellect was saved when the intelligent gorilla Monsieur Mallah preserved his brain in a robotic container; thereafter the Brain swore revenge against Caulder and the Doom Patrol. The group's initial stated aim was world domination, though it is later revealed that at least part of the Brain's objective was personal vengeance against Caulder and his colleagues. The original lineup cited in source material consists of the Brain, Monsieur Mallah, and their first recruit, the shapeshifter Madame Rouge. Over decades of serialized stories the organization has reformed, briefly rebranded as the Society of Sin, and inspired splinters such as the Brotherhood of Dada (founded by Mr. Morden after his transformation into Mr. Nobody) in subsequent narratives.

The Brotherhood has no single uniform appearance; it is represented visually by its members. The Brain is depicted as disembodied cerebral tissue preserved within a robotic container. Monsieur Mallah appears as an intelligent, physically formidable gorilla. Madame Rouge is shown as a shapeshifter whose outward form varies. Other named associates and brief allies in the group's history (per the provided summaries) include figures like General Immortus, Garguax, Mr. Morden (later Mr. Nobody), and later additions such as Phobia and Trinity, producing a roster whose visual elements change across incarnations rather than a single emblematic garb.

As an organized faction the Brotherhood's capabilities derive from the combined powers and technologies of its members and their coordinated criminal strategies. The Brain contributes high intellect, strategic leadership, and use of preserved-brain technology; Monsieur Mallah supplies physical strength and tactical support as an intelligent gorilla; Madame Rouge provides shapeshifting and had been subject to mental-conditioning; Phobia (in later storylines) wielded fear-manipulation. The group employs technology and scientific devices (e.g., preservation of neural tissue in robotic containers, robotic devices operated by henchmen such as Mr. Morden) and engages in kidnapping, brainwashing/mental manipulation, theft (for example stealing one of Robotman's spare bodies in a plot), and large-scale threats including an episode where they threatened Codsville with a nuclear weapon. Their behaviors include recruitment through conditioning, betrayal and reorganization, and targeted vendettas (notably the Brain's campaign against Niles Caulder and the Doom Patrol).
