@theantiheroeshero Yeah ofc! Sorry for the month late reply.
So Cass was basically bred to be the perfect warrior and raised by her blood father to be that way as well. She's top 3 greatest martial artists in DC because her father trained her in such a way that replaced her ability to communicate verbally (speak) with an ability to perfectly read people's body language. She can see what someone is planning on doing and pick out weaknesses this way. She went against her father with the help of Batman and was later adopted by him. She's had various titles that you can choose from.
Since joining the Batfamily, she's learned to speak, but she has problems reading and writing. She absolutely hates any sort of killing because she can literally read the pain and fear on a victim's body as they die. She's very kind and understanding, but will tease those she's close to, and would probably join a pranking scheme. She's quick-witted, even if she's not the genius some other members of the family are. Due to her strict morals and insane fighting ability, she is a top choice to pick up the Batman Mantle. She seems to enjoy dancing and is good at it due to her ability and the control she has over her body. Much like Damian, she had to learn a lot about normal life after escaping her assassin father, but she's come far. She is very emotionally passionate and loves deeply. She doesn't really HATE anyone, even if they deserve it, but sometimes people go too far for forgiveness.
