Robin is the name of several DC Comics characters, all of which have been sidekicks of Batman as well as the leader of the Teen Titans.
Robin made an off-screen appearance in "A Hero Sits Next Door", where he chooses to stare at a nude Peter rather than a nude Wonder Woman, implying homosexuality.
He appeared in "Stewie Loves Lois", where he starred in his own movie Robin: Boy Wonder.
Robin is voiced by Seth Green.
For the Superfriends opening for "Family Goy", Stewie Griffin assumes the role of Robin to Brian's Batman.
