Young Justice (2010)

This cartoon show made for kids but loved by everyone has one of the biggest cult successes in recent years. The show follows a team of Titans (Aqualad, Robin, Kid Flash, Artemis, Superboy and Miss Martian) in the early years of their careers as superheroes. While the first season was focused on the smaller team, the second season which went on to be called Young Justice Invasion was set 5 years after the first season and focused on a much larger team with a wide variety of teen heroes.
With amazing art and character development, the show will forever go down in animation history for DC Entertainment as an all time great. Let us just hope that Netflix or someone can finally make a season 3 so we can find out what happened to [SPOILER].
