By the age of nine, Drake had deduced the identities of Batman and Robin as Bruce Wayne and Dick Grayson after witnessing a gymnastic move by Robin that he previously saw Grayson display in the Flying Graysons. Inspired by the heroes' exploits, Tim trained himself in martial arts, acrobatics, detective skills, and scholastics to better himself both physically and intellectually. When Tim reached the age of thirteen, he saw that Batman had grown reckless and violent following the second Robin (Jason Todd)'s murder by the Joker.
