Honorable Mention 2: The Defenders

Honorable mention number two!

The Defenders are indeed pretty great. This is one of those teams that seems thrown together but actually sticks quite well. We have The Hulk, Doctor Strange, Namor the Sub-Mariner, and the Silver Surfer. When placed all together, they create a pretty rounded-out squad. For a founding member of the Avengers, The Hulk doesn't really work with most teams, but he fits right in with the other misfits and outcasts of this team.

Namor usually functions as a villain, but when he's feeling more heroic, he has a nice dynamic with the formerly villainous Silver Surfer and the troubled Doctor Strange. Together they form the team that shouldn't be a team. Plus, when later members like Hellcat and Beast eventually started springing up, the team expanded in new ways.

Oh, and the Nighthawk-led version from The Last Defenders was also pretty great and extremely underrated. Pick that series up if you get the chance.
