Dick Grayson :
Dick Grayson was a 10-year-old acrobat, the youngest of a family act called the "Flying Graysons". A gangster named Boss Zucco who had been extorting money from the circus killed Grayson's parents, John and Mary, by sabotaging their trapeze equipment as a warning against defiance. Batman investigated the crime and, as his alter ego billionaire Bruce Wayne, had Dick put under his custody as a legal ward. Batman rigorously trained the boy, teaching him hand-to-hand combat, martial arts, and detective skills. During this time he came to love Batman as a second father. Together they investigated Zucco and collected the evidence needed to bring him to justice. He eventually left Batman's shadow entirely to assume the identity of Nightwing.
Recently, after Wayne's death, Grayson has taken over the mantle of Batman.
Jason todd :
He was a black-haired street orphan who first encountered Batman when he attempted to steal tires from the Batmobile. Batman saw to it that he was placed in a school for troubled youths. Weeks later, after Dick Grayson became Nightwing and Todd proved his crime-fighting worth by helping Batman catch a gang of robbers, Batman offered Todd the position as Robin. Jason todd was when the joker beat the youngster severely with a crowbar, and left him in a warehouse rigged with a bomb. Jason Todd later returned as the Anti-Hero Red Hood when he was brought back to life due to reality being altered.
Tim drake :
At the age of nine, Drake surmises their secret identities with his instinctive detective skills, after watching Batman and Robin battle against the Penguin on a security tape shown on TV. While the Penguin was attempting to catch Batman unaware, Robin pounced on the Penguin after executing a quadruple somersault, which Tim had witnessed Dick execute during the final performance of the Flying Graysons. Knowing that only Dick Grayson could execute such a feat, Tim makes the connection and follows Batman and Robin's careers closely
Years later, after Batman grows progressively more violent and reckless following Jason's death, Tim seeks out Dick Grayson to try to convince him to reprise his role as Robin. Reluctant to take a step back, Dick agrees to assist Batman again, but only as Nightwing. Tim, who is unsatisfied with Dick's decision, continues to argue that Batman needs a Robin. Finally, he coaxes Alfred Pennyworth to help him, and taking the Robin costume from the Batcave pursues the original Dynamic Duo where he proves to be an invaluable asset in the capture of Two-Face.
Both Dick and Alfred can see that Tim is well suited not only as Robin but also as a force to keep Batman grounded emotionally. Although Batman is very reluctant to have another partner, he grudgingly agrees that the boy has potential and then begins an extended training period in which Tim endures months of physical, mental and psychological tests.When Damian becomes the new robin Tim drake becomes the Red Robin
Damian Wayne :
Damian Wayne is the illegitimate child of Bruce Wayne and Talia al Ghul, thus the grandson of immortal terrorist Ra's al Ghul. Batman was unaware of his son's existence for years until Talia left Damian in his care. Damian is violent and lacking in discipline and morality, and was trained by the League of Assassins. Learning to kill at a young age, Damian's murderous behavior created a troubled relationship with his father, who vowed never to take a life. Originally conceived to become a host for his maternal grandfather's soul as well as a pawn against the Dark Knight, Batman saved his child from this fate which forced Ra's to inhabit his own son's body, and Damian is affectionate to his father. After Batman's death , Talia leaves her son under Dick Grayson and Alfred Pennyworth's care and Damian is deeply affected by his father's absence.
