ShoNuff44 did a great job on my two Gold Digger setting OC cat girls.
Alex was born on Earth. Her mother is an American pilot stationed in Japan and her father is businessman whose company provides supplies the base that she was stationed on. Alex became a pilot herself and learned of her ability to change into a were-tigress when she piloted a experimental plane very close to the moon. Alex is a something of deadpan snarker. I played her in a pen and paper RPG and she was fun because she could always say the things I wanted to but wouldn't. She has a background story about her father having a curse that prevented him from transforming and the curse actually helped pass lycanthropy on to her because according to Fred males generally don't confirm lycanthropy on to their offspring. Last time I saw Fred at A-kon, I asked about it and he basically said that he thought that women generally pass lycanthropy on by there Aura, but it wasn't set in stone.
Crystal has a fairly detailed backstory. She's a were-lioness from Jade. In her youth she had dreams of being a hero and stopping the bad guys. As an adult she ended up being recruited into an organization on Jade that attempted to do just that. Imagine the CIA, but in a fantasy world like Jade, and you have a pretty good idea. The problem was that Crystal became something of an assassin, and increasingly her missions changed from "Stop X from doing evil plot" to "Take out X before he does something." On her last mission she nearly killed a child by mistake and this forced her to reevaluate her occupation. Because she belong to a secret shadowy organization without a real retirement plan, she ended up leaving Jade to hide out on Earth. She came to Earth during the 1960 and developed a hippy persona appropriate to the time period, and also discovered that she had a talent for enchanting crystals earning her the name that she goes by now. Also during this time she still continued to practice archery, and came to the attention of a retired silver age superhero. This hero who I tentatively call Bowman, was a Green Arrow type character. He convinced her to take his placed and fight crime. Crystal who was now a "do not kill" pacifist started making enchanted arrowheads out of crystal using them in a way similar to how Hawkeye and Green Arrow use their gimmick arrows. She managed to do this without ever using her were-lioness form. Dur ring a battle with a time-traveling villain, she was hurled forward into the 1990s where she retired again do to the violent kill or be kill nature of that time period. I always envision her a female Rurouni Kenshin, with a bow rather than a sword, and I based the goofy side of her personality on Phoebe from friends. You can't tell from this picture but she dies a lock of her hair in a rainbow pattern. I'm open to suggestions for her superhero code name and her mentor's. Oh, I almost forgot, when Crystal returned to Jade, she started acting as a ranger type and developed a healing talent that mostly works on animal. She healed an injured wabbit that had it's weapon tail cut off in a fight. With her skill the wabbit was able to regrow and even stronger weapon tail. The wabbit is named Nyssa. While Nyssa does care about Crystal, she doesn't admit it to herself and believes that she only hang around in case she needs more healing.
