Robin (Tim Drake)

Tim Drake was the identity of the second Robin.

Biography
Tim Drake was the son of Gotham City criminal Steven "Shifty" Drake, who was often a thug for the crime lord Two-Face. He had very little respect for his father, and often had to fend for himself. Around the age of 10, Tim began to idolize Gotham City hero Batman and placed newspaper clippings on his wall. After Batman left a batarang behind at a crime scene, Tim found it and began using it himself.

When his father double crossed Two-Face, he left Tim a note and a key to a Gotham City airport locker. This key was discovered by Two-Face's henchmen when they briefly kidnapped young Tim. Two-Face flipped his coin, and decided to execute Tim, but Batman showed up and rescued him.

Soon after, they discovered that Tim's father was killed outside of Gotham. With no place to go, Bruce Wayne adopted Tim and began to put him under his tutelage as the next Robin.
