Need tattoo ideas for a character I'm developing?

I'm a screenwriter/filmmaker and I'm in the character development stage right now. The character is a girl who has been on a mission of vengeance for something terrible done to her years ago. she is gonna be tattooed from the neck down and I wanted them to reflect her need for vengeance. any suggestions or links would be helpful. preferably all B&W or color that could easily can be done in B&W as well.
