Timothy Drake (Earth-1543)

"Tim Drake is not Bruce Wayne. He isn't Grayson, or even Jason. Drake is different. Look behind his eyes. I suspect he's already won."

History
Tim Drake is a vigilante and member of the Batman Family. He became the third Robin at a young age, succeeding Jason Todd as Batman's sidekick.

Origins
Timothy Drake, then a young boy, was in attendance at the circus on the night the Flying Graysons were murdered. Some years later, he saw footage of Batman and Robin apprehending the Penguin, and the lad was deeply impressed when Robin performed a quadruple somersault (a rare maneuver that only Dick Grayson and a few others could perform). When Tim eventually learned that Grayson was Bruce Wayne's ward, he (quite impressively) deduced that Wayne had to be Batman, and Grayson, Robin.

Tim followed the adventures of the Dynamic Duo over time, and when a new hero, Nightwing, appeared, Tim correctly deduced that he was Dick Grayson who had struck out on his own and assumed this new identity. As a result, Tim began to consider approaching Bruce Wayne in hopes of convincing him that Batman needed a Robin, and that it was him who should assume that mantle.

Batman, eaten up with grief after the death of Jason Todd at the hands of theJoker, became ever more reckless and dangerous, thus convincing Tim even more strongly that a "replacement" Robin was needed, finally driving him into action. But Tim (much like his soon-to-be mentor, Batman) does not act rashly nor impulsively, instead opting to wait for the optimum time to arrive.

His chance came when he learned that Nightwing had left the Young Ultimates for a short time in order to find himself. So Tim followed Dick and convinced him that Batman needed help. Grayson then took Tim to the Batcave and left, as Nightwing, to help Batman deal with the vile Two-Face. Alfred Pennyworth (always the helpful one) insinuated that Tim was brought to the Batcave to help Batman as the new Robin. But with Clayface on the loose, Tim and Alfred became worried about the safety of Batman and Nightwing, and went out to help them.

Tim donned the costume of Robin and, with the help of Alfred, managed to rescue them. Batman accepted Tim as the new Robin on a trial basis. He trained over several months, first with Alfred, then Batman, and, finally, Nightwing.

After assisting in the defeat of Scarecrow, Batman finally deemed Tim was ready to fulfill his role as the new Robin. He was given a new costume that set him apart from the previous Robins.
