From GTO we have the Batman 3D Black Belt Buckle Bat Symbol.

(A Little Batman Fact) In a retelling of the origin of Batman's sidekick, Robin: Bruce Wayne and Vicki Vale are at the circus watching "The Flying Graysons," an acrobat family consisting of twelve-year-old Dick Grayson and his parents. When Grayson's parents are shot to death by a hit man, he is escorted from the scene by several cops of the Gotham City Police Department in a threatening manner. Vicki and Alfred Pennyworth chase after them. Batman begins searching for the killer and then rescues Dick Grayson from the police, telling him that he has been drafted into a war. More police chase after the Batmobile with orders to kill Batman, during which Vicki is seriously injured. Dick is frightened by Batman's violently ramming the police vehicles during the chase. When Dick begins to cry, Batman smacks him, though he then catches himself, questioning these actions. He tells Dick he will find his parents' killer, and tells him not to trust the Gotham police.
