Very little info is given about Danielle's past, other than the fact that she grew up to be very close with her brothers, Joseph and Joshua. She excelled in both academic and physical pursuits, graduating from college with one of the highest GPAs that her university had ever seen. Shortly after her graduation, she would marry her long-time boyfriend, Brian, and would maintain their relationship. She would get a job working for the Game and Parks Commission studying indigenous birds of prey.
Unfortunately, Brian passed away less than two years later. This tragedy sent Danielle and Joseph, who saw Brian not only as a brother-in-law but as a surrogate father, into a time of grief, and galvanized Danielle's devotion to her younger brother. The siblings would decide to live together in their childhood home, where they would help each other cope with their loss. Eventually, her eldest brother, Joshua, would accompany the pair to comfort them while they mourned.
Danielle is described as being protective and nurturing by heart and acts as a motherly figure towards Joseph, although her caring personality would not stop her from becoming a fierce warrior.
Shadow of Oblivion was released in 2000 for the Nintendo 64 and Game Boy Color. The story takes place two years after Seeds of Evil and follows Joshua and his sister Danielle and brother Joseph as they battle a cosmic entity known as Oblivion. Both Joseph and Danielle are playable characters.
