The third person to become Robin. Tim is different from all the other Robins because he wasn't an orphan, asked to be Robin and wore long pants instead of wearing the famous green short pants that Dick Grayson and Jason Todd wore.
It should be noted that while his parents do die making him an orphan like the others, he didn't start out that way.
Later Tim adopts the identity of Red Robin when Damian Wayne the fifth Robin takes on the role. However, this is short lived thanks to retcons in the DC universe.
Recently, Tim came out as Bisexual and is currently dating a guy.
