Teen Titans (2003-2005)

Not to be confused with the disturbing show Teen Titans Go, Teen Titans is a show helped me get into the comic book world even more. The show centered around perhaps the most popular team of titans, unlike Young Justice, including Robin, Starfire, Beast Boy, Cyborg, and Raven. These teen heroes tangle with great villains like Mammoth, Raven's father and of course the big bad Slade (aka Slade Wilson/Deathstroke).
With great humor and great characters a part of a strong team of heroes, the show is one of the strongest DC ever created.
