Young Justice focuses on the lives of a group of teenaged superhero sidekicks and protégés attempting to establish themselves as proven superheroes and as teenagers dealing with adolescent issues grounded in the context of their personal lives.It's similar to the Teen Titans series that came out a while back, but this is more serious and the drawing style is more American. Teen Titans' style was more based on anime, even the theme song was sung by a Japanese girl band.
My favorite characters in this series so far are Aqualad and Kid Flash. I like Aqualad because he's a badass, and he makes me think I should really give Aquaman a second chance. Kid Flash is just funny, and the chemistry between him and Robin is always fun.
