"I've been avoiding you. It's... your background. The assassin training and all that. It's just... my childhood's so normal.

It takes a special kind of person to put the fear of God into Robin, and Cassandra Cain is most definitely that kind of person.
The daughter of David Cain and Lady Shiva, she grew up without any form of human contact and wasn't allowed to speak as she was trained to become the world's greatest assassin - and oh boy, did it work.
She made her first kill at the age of eight, a bookmaker named Faizul, and this affected her so badly that she ran away and didn't resurface until No Man's Land.
After she managed to prove herself to Batman, he adopted her and trained her to become the new Batgirl. So, on top of all the training she received from her father and mother she also got to learn from the Dark Knight himself, which has made her one of the deadliest people on the face of the planet.
