Tim Drake
In The New Batman Adventures Tim Drake became the second person to brand the Robin costume. Tim was the son of a thug named Steven Drake. He worked for the crime lord Two-Face for quite some time. Tim's father was never really around so he spent most of his time idolizing Batman and even putting clippings of his actions on the wall. Tim's father began to have problems with Two-Face. When he doubled crossed him Steven fled the city, leaving his son a note and a key to a locker at a Gotham City airport. Two-Face found out about the key and went after Tim. This led to him kidnapping and almost executing him, but Batman was able to get there and rescue him from Two-Face. Later on, they found out that Steven was killed outside of Gotham. With no one else to take care of Tim, Bruce decided to adopt him and trained him in several martial arts, this led to Tim becoming Robin and taking over (for Dick Grayson, the original Robin) as Batman's sidekick.
