John Grayson is the brother of Alphonse Grayson and the fiancee of Mary Lloyd. He is a member of the Flying Graysons.


Having a romantic relationship with Mary Lloyd, it was hindered by the family feud between the Graysons and Lloyds. When Lila Valeska was murdered, and Alphonse Grayson and Owen Lloyd were arrested due to a fight between the two, John was examined by Dr. Leslie Thompkins, who John told that fight was caused by Mary's idiot uncle Owen. At the Gotham City Police Department headquarters, the two later argued over who had murdered Lila Valeska. John along with Mary later returned to thank Gordon for figuring out who had actually killed Lila, leading their two families to reconcile, and John and Mary getting together.[1]
