8) Rogues
It’s not unusual for a superhero’s rogues gallery to team up in order to increase their chances of winning. Few of these uneasy alliances, though, have developed such a long-standing camaraderie as the Rogues, the collective foes of the Flash. The scourge of Central City, the group usually consists of Captain Cold, Heatwave, Mirror Master, Weather Wizard, the Trickster, Abra Kadabra and Captain Boomerang.
What separates the Rogues from many supervillain teams is that they have a strict code of conduct. These guys are mostly just thieves and forbid murder, drug abuse or other such serious crimes. Just because they’re interested in their own personal gain first and foremost doesn’t mean they have no standards, you know.
Just about all of the Rogues have appeared on The CW’s The Flash, with various team-ups forming between the villains over the show’s three seasons so far. There are also rumours that the Rogues will feature in the upcoming Flash movie, too.
7) Dark Avengers
The Dark Avengers are essentially the opposite of the Thunderbolts. Whereas that team consisted of supervillains who intended to be evil but grew to love being good, the Dark Avengers aimed to change their evil ways but eventually fell back into old habits.
In Brian Michael Bendis’ Dark Reign storyline, Norman Osborn is put in charge of S.H.I.E.L.D. due to his role in dispelling the Skrull invasion of Earth. The Avengers are disbanded and in its place he recruits a bunch of villains to take up established superhero identities. Osborn himself becomes Iron Patriot. Logan’s evil son Daken becomes Wolverine. Venom calls himself Spider-Man. Moonstone masquerades as Captain Marvel and so on.
Osborn’s Dark Avengers represent pretty much a nightmare scenario for Earth’s Mightiest Heroes. They’re not only a team of villains vindicated by the government, but they’re doing evil in their name.
