Suicide Squad, Justice League Dark, Gotham City Sirens, Birds of Prey, Young Justice, Teen Titans / Titans, Justice League, Legion of Super-Heroes, Legion of Doom, The Outsiders, Justice Society of America, Doom Patrol, Secret Six, Freedom Fighters.

I haven't read anything about these teams, only know about them through movies, TV shows and animation. I want to read more about them. Any suggestions?
