Tim Drake is the son of Jack and Janet Drake. When he was a child, he visited the circus with his parents. The Drakes managed to get a photo with the Graysons before the show, the night Tim Drake met Dick Grayson for the first time was also the night when Dick Grayson's parents died.
Tim Drake had followed Batman and Robin's career ever since the murder of the Flying Graysons. He had excellent detective skills which helped him discover the identities of the dynamic duo. One day, he saw the original Robin on television performing a move Dick Grayson had executed the night he went to the circus with his parents. He quickly made the connection that Dick Grayson was Robin and after leaning that Dick Grayson was the ward of Bruce Wayne, he realized that Bruce Wayne was Batman.
After the death of Jason Todd, Batman grew more violent and reckless. Tim noticed that this wasn't in Batman’s true character, and he sought out the help of Dick Grayson. At this time, Dick had been going by the code-name Nightwing. Tim tried to convince Dick to retake the mantle of Robin, saying it was the only way to keep Batman sane. Dick agreed to this, but said that he would only help Batman as Nightwing. Tim did not like Dick’s decision and continued to argue that Batman needed Robin. Eventually, he was able to get Alfred to assist in altering the Robin costume so that he could help Batman himself. Alfred and Dick gave Tim their approval as the new Robin, but only so he could keep Batman sane. However, Batman protested that he did not want a new partner but also added “The boy has potential.” Eventually, Batman skeptically accepted Tim as Robin but under one condition: Tim had to endure physical and mental training from Bruce before he could become Robin so that he would not suffer the same fate as Jason Todd.
While Tim was still training, his parents Jack and Janet Drake were kidnapped by a mysterious stranger. Tim continued to focus on his work and foiled the plans of a hacker-thief. Meanwhile, Batman went to rescue Tim’s parents. However, Batman arrived too late. Tim's parents were poisoned. His mother had died, and his father fell into a deep coma. With the tragedy that Tim and his parents went through, Batman became worried that Tim might go down the road of vengeance, and it would cloud his judgment. However, Tim proved Batman wrong when he saved Batman and Vicki Vale from the Scarecrow. Afterwards, Batman allowed Tim to take on the mantle of the Boy Wonder and gave him a more modern version of the costume.
Tim Drake is the Robin that appears in the video game Batman: Arkham City. In the game he made a brief cameo in the main story, but was playable in the challenge rooms and story DLC.
