Origin
Sandra Woosan was the goddaughter of the martial arts expert O-Sensei. When Sandra Woosan’s sister was killed, a mysterious man approached her and convinced her that Richard Dragon had killed her. Sandra became determined to avenge her sister's death, but knew that she had to train if she were to have any hope of defeating Richard Dragon. While training, Sandra discovered that she had a natural talent for the skills and movements required for martial arts.

She trained for years, eventually reaching a point in her martial arts training where she felt that she was ready to find Richard Dragon and avenge her sister. She decided to take up the code-name Shiva and eventually tracked Dragon down, luring him into a trap. However, Dragon revealed to Shiva that he did not kill her sister and the man that told her he had was someone that worked for him and wanted Dragon dead. He then explained who the real killer was and that he had already killed him in battle.

Shiva came to the devastating conclusion that she had no more purpose in life and that all her training had become a waste. She decided to aid Dragon with some of his missions because all she knew was how to fight. Dragon let her come along in hopes that she would decide to use her skills for good. After many years, Dragon decided to retire and Shiva left to find meaning in her life. Later, she again partnered with Richard Dragon and Ben Turner, The Bronze Tiger and went on numerous missions for the mysterious G.O.O.D.
