- We have a common enemy. The Teen Titans and their friends will fall. Working together we will defeat them...one...by...one.
- — The Brain
The Brotherhood of Evil is an evil organization bent on world domination led by The Brain and his associates Monsieur Mallah, Madame Rouge and General Immortus, and who have been old enemies of the The Doom Patrol. However, their new main enemy becomes the Titans after Homecoming - Part 2. After the Brain decided that the Titans will be a bigger threat than the Doom Patrol, he attempted to eliminate all Titans.
The Brotherhood and the Doom Patrol have clashed on numerous occasions in the past; the only instances recorded in the series involved a Black Hole Generator which could be opened and closed in any location of the Brotherhood's choice.
Because of their frequent conflicts, the Brain and General Immortus were gradually able to analyze and predict the Doom Patrol's modus operandi, which was further benefited by Mento's stubborness and inherent drive to see a mission finished no matter what. Finally, they managed to trap the Doom Patrol (sans Robot Man, who was left deactivated) during a mission in the Brazilian jungle, where the Brain's forces were scavenging materials to charge a power cell for their newest version of the Black Hole generator. Mento managed to send an alarm probe to his former protegee, Beast Boy, who arrived with his new teammates, the Teen Titans, and managed to free the Doom Patrol, though the Brotherhood leaders escaped to their secret base, which also housed the Generator.
Mento, insistent that only the Doom Patrol could fight the Brotherhood efficiently, drafted Beast Boy back into his ranks and set out to destroy the base, but owing to various hazards set by the Brotherhood, only Mento and Beast Boy managed to arrive there. But in the meantime Beast Boy had managed to persuade Mento that his usual ramrod approach was no good, and both overcame the base's defenses by using their heads instead. In addition, the other Titans, who were reluctant to leave Beast Boy by himself, also arrived, having rescued the rest of the Doom Patrol on the way, and joined the two in their assault, during which Beast Boy cunningly set the Generator to destroy itself.
However, the Brotherhood now saw the Titans and their compatriots as their primary enemies due to their youthful unpredicability. Thus the Brain hatched a plan to defeat Earth's youngest generation of superheroes before they could get properly organized: they conducted odd attacks on Honorary Titans, both to alarm the Titans and to obtain a Titans Communicator in order to track them once a proper network had been established. Madame Rouge managed to obtain a com device from Hot Spot, and after all Titans and Honoraries had been connected, the Brain executed its plans, taking out the young heroes one by one while they weren't assembled into one team. Because the Brain's plans were so well thought out, many of the Titans were defeated and captured. Wildebeest, Hot Spot, Argent, Robin, Bushido, Speedy, Killowat, Thunder, Lightning, Aqualad, Tramm, and Menos were all defeated and flash-frozen as trophies.
But what the Brain failed to consider was that several Titans, chiefly Beast Boy, were not defeated. Beast Boy met up with the Herald, Mas, Jericho, and Pantha and led them in an assault at the Brotherhood base, starting a massive war. However, they were severly outnumbered and were eventually defeated after putting up a valiant effort. Just as they were going to get frozen, reinforcements arrived. Cyborg burst through the ground with Kole and Gnarrk, Starfire blasted in with Bumblebee and Red Star, and Raven teleported in with Melvin, Timmy, Teether, and Bobby, and the battle restarted. When Más y Menos managed to unfreeze the Titans who had already been captured, the Brain's plan backfired spectacularly, and in the end the Brotherhood leaders and most, if not all, of their allies were captured and flash-frozen themselves.
Brotherhood Allies Edit
The Brotherhood of Evil's list of allies includes most of the villains who have previously appeared in the animated series plus several new characters who had to date no previous appearances (such as Cheshire and Phobia). In addition, several villains are refeatured who were subject to defeats which had left them permanently incapacitated, but who nevertheless made at least a cameo appearance in Homecoming - Part 2 (such as the Puppet King, Malchior, Atlas and Ghostfreak). The only villains not featured here are Slade, Brushogun, Trigon, Brother Blood, Krall, Soto, and Blackfire. The Cironielian Chrysalis Eaterwas eaten, so presumed by most viewers that she was left nearly incapacitated. Since Homecoming - Part 2, Jinx, Red X and Doctor Lightdecided to leave the Brotherhood. A select few did not participate in capturing the individual Titans. The rest of the villains, as they appeared in above episode, are:
