The Brotherhood of Justice are a group of superheroes residing in the parallel universe of Jump City. They are heroic counterparts of the Brotherhood of Evil and their enemies are the Teen Tyrants, the evil counterparts of the Teen Titans.
Teen Titans Go!
The Brotherhood of Justice make their only appearance in issue # 48 in Teen Titans Go!, where they are implied to be the only superheroes remaining after the Teen Tyrants conquered their version of Jump City. Gemini, a member of the Brotherhood of Justice, is a member of the Teen Tyrants, but is actually spying on them. After the Teen Titans invade the Teen Tyrants' universe to save Killowat, they are confronted by the Teen Tyrants and are defeated by Red Raven's powers. At this moment, Gemini uses this chance to betray the Teen Tyrants and opens the door to reveal her teammates on the other side. Due to their superior abilities, the Brotherhood of Justice are able to distract and defeat the Teen Tyrants, giving the Teen Titans time to successfully rescue Killowat despite Robin's insistence that he and his team help Gemini. They aren't seen again as Raven permanently closed the portal to their world shortly after retrieving Killowat.
