SaNe: The Robin in the Teen Titans animated series is Dick Grayson, you can see him as Nightwing in the episode in which Starfire goes to the future. I'd say the hair is just messy instead of his usual gelled back look.
SaNe: @Anonymous: Pants are just an article of clothing, there's no Robin nowadays who uses the very original outfit. I'd look more at Robin's weapon of choice, the bo staff that came straight from Tim Drake. But anyway, the Robin in Teen Titans is Dick Grayson and there is a lot of evidence in the series supporting it. Him being Nightwing in the future, him being the leader of their group as he was in the original Teen Titans comics, Larry (Robin's counterpart from alternate dimension) who's real name is Nosyarg Kcid (Dick Grayson backwards) and plenty more.
On the topic of Wilsons, seriously disappointed by the lack of Jericho. He and Rightwing were practically a couple in canon.
