2) The Avengers
Marvel’s mightiest superhero team can only be the Avengers. In 1963, Stan Lee and Jack Kirby had the idea to unite Earth’s Mightiest Heroes for one continually bestselling comic book series. Originally consisting of Iron Man, Thor, Hulk, Ant-Man and Wasp (with Captain America joining shortly afterwards), the team has expanded over the years to include pretty much every single Marvel hero at one point or another.
As well as all the extra action and scale that comes from all these superheroes teaming up, the Avengers stands head and shoulders above other superhero teams because of the basis in its characters. From a man out of his time to a tragic scientist with a terrible affliction, the Avengers also face personal and social battles as well as global and interplanetary ones.
They’ve been one of the hottest comic book groups around for years, but right now, with the success of the Marvel Cinematic Universe on the big screen, they’ve also become one of the most popular superhero teams in the world.
