While Batman has grown an extensive collection of allies over the years, one of his closest is indisputably Dick Grayson, better known as Teen Titans. While there are many instances that illustrate just how much he changed since he abandoned the Robin persona, Nightwing mourning his parents shows exactly how the Teen Titans changed him forever.

Dick Grayson began his superhero career as Batman’s first sidekick, Robin. As a young boy, Nightwing’s parents were brutally murdered, which led to Bruce Wayne adopting the young orphan to raise and train him as a potential successor for the cape and cowl. As Grayson matured, he ed the Teen Titans team and eventually outgrew the Robin persona, adopting the Nightwing identity. Over the years, Nightwing has become a symbol for a kinder approach to Batman’s war on crime, with a large emphasis on empathy and more recently, urban renewal and charity.
