After the succesful inclusion of the female convict Maria "Princess" Alvanez, who scored in her 3 first tournament matches, the ward decided to add another woman to the team. Cassie "Kiss of Death" Kingston is about as tough as women come and spread fear around her in prison block. The small town girl was never known for good looks, but instead relied on her strength and determined nature to get the job done.

She earned money in bars by entering in arm wrestling fights, drinking contests etc. She currenltly serves 10 years in prison for killing a man by a single blow. According to witnesses the victim, a seasoned biker, couldn't handle losing to Kingston in arm wrestling and swung at her first.
