My favorite character in the DCU is Dick Grayson/Nightwing. Nightwing was the leader of the Teen Titans. He was Robin "the Boy Wonder" and decided to step out of Batman's shadow and became Nightwing. Dick Grayson/Nightwing should be portrayed by actor Sean Faris (Never Back Down). Sean faris is a good actor and has the right look and build to play the part.
Raven is another great character. Raven created the New Teen Titans. I think actress Kristen Stewart (Twilight series) should portray Raven. Even though i hate Twilight, Kristen Stewart is a good actress and has the right look.
Victor Stone/Cyborg was a promising decathlon athlete until he got into an accident and almost died. Victor's father replaced half of his son's body with experimental robotic parts to save his son's life. Victor Stone/Cyborg should be portrayed by actor Christopher Massey (Zoey 101). I think Christopher Massey is a good up and coming actor and has the look of Victor Stone.
Kyle Raynor/Green Lantern is another Titan. Kyle took over the duty of being a Green Lantern from Hal Jordan. Kyle should be portrayed by actor Tom Welling (Smallville). Welling is a good actor and has the right look. People are gonna hate me for this choice because he already plays Clark Kent on t.v. and people think the show sucks.
The villian is Slade Wilson/Deathstroke. Deathstroke is a hired assassin who hates the Titans. Deathstroke should be portrayed by actor Stephen Lang (Avatar). Stephen Lang is a great actor and has shown he can play a great bad guy. He also has the right build.
