A YJA Moment - The Bat Family

Bruce Wayne was the first known wearer of the cowl, though rumors persist of his father donning a dark costume and fighting crime decades prior.  After the death of his parents, Bruce traveled the world, learning the skills that it would take to become the vigilante protector of Gotham known as The Batman.

Soon after becoming the Caped Crusader, Bruce would take in a young boy whose circus performing parents were murdered by the Gotham mob.  Dick Greyson would then train under Batman, becoming the first Robin.  After years as a side-kick, he would form the Young Justice team and eventually become his own hero Nightwing, acting as a protector of Bludhaven when he wasn't working for the Office of National Emergency as Agent 37.

The mantle of Robin would be taken by several individuals - Jason Todd would be killed by the Joker; resurrected by the League of Shadows to become the second Red Hood; Tim Drake would serve as Robin until he was framed along with Batman by Lex Luthor, forcing him to adopt the Red Robin mantle. Currently, Bruce's biological child Damien Wayne serves as Robin.

Barbara Gordon, daughter of the GCPD Commissioner Jim Gordon, would independently become the young hero Batgirl.  Though Batman was initially against her joining the Bat-family, she proved herself capable and joined Young Justice.  Barbara was gravely injured by the Joker and was confined to a wheelchair, becoming the expert hacker known as Oracle.

Much like Batgirl, Kate Kane was inspired by both her cousin Bruce (Batman) and her Aunt Kathy Webb (briefly the original Batwoman), to become the latest incarnation of Batwoman.  She had no intention of joining with Batman but developed mutual respect which made her an unofficial member of the family.

Stephanie Brown was the daughter of the minor villain Cluemaster and became the hero Spoiler in order to thwart his plans.  Eventually, she would become friends with Tim Drake and gained the confidence of Batman.  When Barabara was forced to retire, Stephanie was asked to pick up the mantle of Batgirl.

Helena Bertinelli lost her family to Mob violence.  Growing up with relatives, she trained hard in order to find and kill her parents, murderers.  Running up with the Bat-Family on numerous occasions, they eventually curbed her lethal intentions and honed her into the identity of the Huntress.

Luke Fox was the son of Lucius Fox, Wayne Enterprises CEO.  Idolizing Batman, Luke trained hard for the opportunity to be mentored by the Dark Knight.  During an emergency at one of Wayne's manufacturing facilities, he came across a prototype for the original Batwing armor utilized by David Zavimbe and used it to defeat the Penguin and his minions.  For this, Batman offered him a position within the Bat-Family as the American incarnation of Batwing.

In addition to his core group of "Gotham Knights" Batman effectively franchised out the Dark Knight methodology, forming Batman Incorporated.  The following are the known members operating around the world: Azrael in Montreal, The Bat-Man in Beijing, the original Batwing in Kinshasa, Daredevil in New York, The Dark Ranger in Sydney, El Gaucho in Buenos Aires, The Hood in London, The Knight in Edinburgh, The Midnighter in Chicago, Mister Unknown in Tokyo, Moon Knight in Detroit, a new Nighthawk in New Orleans, Nightrunner in Paris, Orphan in Hong Kong, The Signal in Los Angeles.
