Bellatrix has the dark mark on her arm and her Azkaban number tattooed on her neck.
- Lust from FMA - Beatrice from Uminkeo - Medusa from Soul Eater - Regina from Once also has a tattoo (rather her actress does and sometimes they slip up and forget to cover it if that counts :P) Also have some neat tattoos
If I listed real people with kickass Татуировки that'd take too long. :P
Abby Sciuto from NCIS. She also has a tattoo under each shoulder, a spiderweb tattoo on the back of her neck, a smiley face on her middle finger I think and the infinity symbol on her right forearm. Sorry, this was the best picture I could find of her.
