Mortal Kombat, Kitana. I had a huge crush on her, and while I absolutely loathed seeing her lose and get fatalitied, it was also a rush. Used to watch matches at the local arcade and browse video game magazines / oldschool websites for pictures of her getting torn apart. Always felt bad when it happened - angry, even - but I couldn't get the thought of my favorite heroine dying out of my head afterwards. Fapped to relieve the stress.
